The Eungam Hana Public Kindergarten is a project that proposes a new spatial concept for childcare facilities that respond to the underdeveloped surrounding environment in high-density urban areas.

It is the first childcare facility of Hana Financial Group to be built in Seoul. The site is an isolated area surrounded by old commercial and residential buildings on three sides except for a narrow one-lane road. Although it is a place where a childcare facility is located, where lighting and ventilation are of the utmost importance, it was difficult to establish a pleasant living environment due to the adjacent buildings that were built very close together.

We put a lot of effort into resolving the irrationality of the old residential area and designing an efficient spatial layout. The context of the site was too poor to experiment with abstract architectural vocabulary and theoretical architectural discourse. Therefore, we tried to approach the site from a thoroughly empirical perspective. We tried to show a typical example of Korean Sustainable Adaptive Architecture in a high-density urban area based on a methodology that can be verified through data and simulation.

Specifically, the high-ceilinged stairwell atrium was placed on the south side to solve the problem of lack of lighting due to the adjacent buildings. Cross ventilation was made possible through the facade that was open to the east and west, thereby responding to the changes in the microclimate around the building. In addition, slender vertical louvers were applied as a device to protect children from the surrounding gaze in the dense land, and many parts, such as the Movable Louver Frame that helps firefighters respond in emergencies, actively reflect innovative architectural methodologies.

The key to high-end architecture in the public sector is how wisely it overcomes realistic constraints with realistic materials and realistic details rather than expensive materials and complex details. Ultimately, these attempts are concerned with creating a comfortable living environment for children using the space exclusively. These efforts have made the results of numerous studies and fierce debates over the past two years a reality.

Our children are beings to be protected without any discrimination and are a mirror to see the future. In that sense, the national and public daycare center project hosted by Hana Financial Group, which has already created a home for children through Suchae's daycare center project, is more meaningful than any other project. This daycare center, which will be built in Goesan, Chungcheongbuk-do, is an important social asset that will meet the demand for daycare centers in existing apartment complexes and new housing districts, and has value beyond a simple daycare center. Its purpose is to realize a daycare center as a sound fence where safety, security, and play can coexist beyond the existing daycare center. In addition, this project reflects the identity of Hana Financial Group and has a strong character of differentiated space branding. In other words, the purpose is to create a space where a variety of interactive indoor and outdoor activities can occur while safety and security are basically guaranteed beyond the location conditions and physical context of the site. Therefore, based on Hana Financial Group's branding, efforts were made to realize a passive and sustainable architecture that combines innovative external space with warm internal space. In accordance with the goal of the HNSS design guidelines, we tried to solve the space around four keywords: Hybrid, Nature, Smart, and Storytelling. Specifically, hybrid play activities were made possible through the spatial composition of the extended outdoor living organically intertwined without distinction between indoor and outdoor floors. Through physical external spaces such as the playground courtyard, sand playground, and terrace playground, communion with nature was possible, and smart education was intended to be possible through the planting room and nursery room where ecological farm experiences are possible.

Since the site is adjacent to conflicting urban contexts, both characteristics of shielding and openness had to be reflected in the architecture. After thinking about overcoming these physical limitations, I was able to come up with an alternative at Hana Financial Group’s daycare BI ‘Hana Green’. Through the design concept of a shape that embraces and protects children derived from BI, it was possible to overcome the physical limitations of the site and at the same time reflect the concept of an emotional space called a daycare center. The initial design direction was set by developing the existing BI motif with the image symbolizing the mother's healthy fetus growing and being protected in the mother's belly. Intuitive mass was embodied in the derived design concept. We maintained the design concept of a shape that wraps around and protects children from the unorganized surroundings. Free activities of children were made centered in the courtyard, and these autonomous activities were intended to be protected from the periphery. At the same time, I thought about how to incorporate conditions with great potential in the existing context, such as connectivity with the surrounding landscape and views, into the architecture. Openness was emphasized with a transparent façade in the direction with good lighting on the south side, and shielding was emphasized with solid materials for the part facing Munmu Apartment and the pedestrian road. The entire building was designed to secure sufficient sunlight coming from the south, and through the courtyard, it was able to receive enough solar radiation even in winter, so that it could become a warm daycare center in all four seasons. Basically, it was intended that outside activities be carried out around the courtyard of the playground, but these activities were inevitably limited to the first floor. Regardless of the number of floors, the deck on the second floor and the roof floor were actively utilized to allow for free movement in and out of the building and various autonomous activities. In addition, the front glass wall with strong openness was applied to the facade of the internal connection bridge connecting the buildings, so that the sunlight received from the south could penetrate into the inner courtyard without being blocked by the building. The first floor was designed to be offset by 1.5m from the outside of the building to function as an outdoor passage in case of rain and as an awning to prevent excessive solar radiation in summer. The entire building was intended to be an organic space that can be integrated and maintained as one system space.

The site is surrounded by surrounding buildings and has somewhat isolated location characteristics. Moreover, due to the narrow site characteristics due to the 3m step difference with the green area on the south side, if the floor area on the lower floors increases, adequate sunlight cannot be secured. The sanatorium is a facility where sunlight and ventilation are very important. In order to overcome these limitations of the site, it was necessary to reduce the area as much as possible on the lower floors, but this was impossible due to the design guidelines. Accordingly, by processing the mass itself slimly, a building shape in the form of a linear garden rather than a courtyard type was derived.

Through the transition space leading to the Curtainwall-Arcade, it was intended to maximize the sense of openness indoors and to give users comfort by allowing them to view the Pocket Garden from the outside. In general, in the case of a flat roof, internal circulation is not performed well due to stagnant air on the upper part. Therefore, the buoyancy of air increases as it goes from the center to the façade, which is intended to promote smooth internal circulation. General curtain wall façades are difficult to adjust according to the season because it is difficult to adjust the sunlight. The arcade-type eaves serve as awnings with an extended roof, which is advantageous for forming indoor shade spaces in stadiums where sunlight is essential. Building Respiration is a methodology that maximizes circulation through breathable construction devices. Light and natural ventilation are provided through the permeable façade. The purpose is to maintain a pleasant indoor climate with a design that considers the direction and degree of sunlight, not just a simple ceiling. In sustainable design, the physical properties of floor materials are an important factor in determining the indoor temperature. In particular, the infrared rays reflected from the outside and entering the room are mainly caused by the increase in the indoor temperature, so a wooden deck with low reflectivity was used for the floor in front of the facade. In the case of a space with a high floor height, excessive illumination is introduced into the interior. Exposure to sunlight can interfere with indoor activities. In addition, in summer, the temperature rises, resulting in an excessive cooling load. It was intended to control excessive sunlight in the winter by placing an awning and to lower the indoor temperature by blocking sunlight in the summer.

With the announcement of the expansion of public housing supply and OSC-based smart construction (incentive), it is necessary to prepare modular-based business conditions for SH Corporation. In order to review modularity in the public housing innovation plan in the future, it is necessary to review the design specialization for small lots and complex-type housing. This study aims at design-specific design of small-scale modular housing and mid-rise modular multi-unit housing to be supplied to parcel-type multi-family and multi-family housing in low-rise residential areas.

The loss of production competitiveness in the traditional construction industry is accelerating due to the limitations of the existing site-centered, skilled technician-centered construction method. Due to changes in labor standards, a decrease in the quantity and quality of technical manpower, and an increase in labor costs, off-site construction (OSC) is being promoted as a policy. Due to the development of construction technology and smart design, the future construction environment, working environment, and technological environment are gradually becoming de-sited and de-managed. In the case of OSC-based PC structure apartment housing, the domestic case is only one case of LH Asan Tangjeong, and since most of them are wall-type PC structures, the need for architectural planning review for the beam-column PC structure demonstration project is emerging. This project was designed as the first OSC-based beam-column PC structure in Korea.

The Heygate estate was designed as a low income social housing located at the South London borough of Southwark. It housed over 1200 families for more than three decade. Prior to the 1930s the area consisted of a suburb of victorian tenements which were considerably damaged during the German bombings in World War II. The council there upon decided to demolish and rebuild in the area rather than repair the extensive damages, leading to a major post war regeneration project designed by architect Tim Tinkers which started in the 1960s and was completed in 1974. Due to economic crisis during its construction it had been constructed quickly with limited funds. In the context of the city in the 1970's the estate had been designed in a manner that separated it from the dirty and polluted surroundings and created a safe and green haven inside. But the rise in unemployment in 1980's there was in increase in crimes and other anti-social activities and there were social and other issues that arose in the estate from this.

Southern facade required extensive environmental research for developing design strategies. This is due to the duration of direct solar incidence upon this facade which vary from 8-12 hours. The orientation makes its necessary to design a facade which utilise the large solar gains successfully during the cool period and negates scenarios of overheating during the warm period. The design strategy at every step has been tested on the Ecotect and TAS for the best combination of daylight. 

Stage1 - The window sizes for units have been derived from the glazing to floor ratios deemed suitable from the Energy index calculation and these are positioned in the facade keeping views and interior spatial quality in context. 

Stage2 - There were shading diagrams calculated from Ecotect and strategies has been developed such that each aperture was shaded from direct solar incidence during the warm period when the sun was at the pear azimuth position. This could be achieved by tilting the facade by an angle of 15degree toward the South along with having a horizontal shading device. The applied also served the purpose of creating a private terrance space which added to the living quality of the flat. The tilt was integrated inward into the structure instead of an extension keeping in context the complication of adding cantilevered extensions to the existing structure as well the thermal problems of cold bridge this would lead to. 

Stage3 - The facade was finally modified by redistributing window sizes and placing windows vertical to further improve daylight performance in living space.

The average annual wind velocity on the north side is 1.15m/s, addition of projected masses shows a reduction of this wind speed to 0.23m/s. But to create more space for outdoor activities these projected masses have been reduced in number and interspersed with lighter structure which functioned in the same manner as wind breaks. The principle that has been used in deciding the position of these projected masses is that if the height of the mass is ‘H’ then the distance between two masses is ‘20H’.

Site simulations conducted on Winair showed that the wind condition on the south of the building was not as poor as the north; this was due to the protection provided by the existing trees on the site. However the wind velocity of 1.15~2.0m/s in the south can be further optimised as according to the Beaufort scale the most pleasant wind for outdoors is less than 1.5m/s. Also according to spot measurments, the actual maximum wind velocity on south side was 4.5~5.0m/s. To attain this condition there can be additional trees planted to function as windbreaks. However the outdoor spaces on the north which have more drastic wind conditions can not be controlled by plantation as the space on the north is insufficient from adequate trees. Thus temporary light structures that create doldrums like spaces within them can act as windbreaks on the northern side.

The strategy on the south is to increase the number of trees which show a reduction of the average annual wind velocity from 1.15m/s to 0.46m/s. In the outdoor spaces on the north side the addition of projected mass and lighter structures function as windbreaks and reduce the wind velocity in the wind channel from 1.15m/s to 0.23m/s. These conditions are satisfactory for optimal outdoor comfort.

The landscape of the site has been planned integrating the surroundings of the site. The outdoors have been planned around three focal nodes, two to the northern side (Node 1 & 2) and one to the southern side. Node 1 is an conjunction of all pedestrian paths connecting the site to the Elephant & castle and Node 2 is where all traffic flowing in from the rest of the master plan reaches the site, both of these nodes are aimed towards use by the public. Node 3 is planned as a more private buffer zone, which can be used by resident, and people from the residential neighborhood to the south. The outdoor has been zoned (Fig 16) guided by the strategic placements of the public and private nodes. The spaces to the north of the building have been designed as commercial spaces for use by the public who visits the site, whereas the region on the south is a quitter and more private space for the residents of the building as well as for access to the residential floors.The trees existing on the site comprise of only deciduous trees, 15 trees to the northern side and 13 trees on the south. These deciduous trees act as good windbreaks in the warm period but in the cool period they have no foliage and hence their impact as windbreaks reduces. The addition of evergreen trees and low shrubs can make these windbreaks effective even in the cool period and create comfortable outdoor spaces. Outdoor design and Facade has been treated at the same time. The facade design was intended to attract the flow from outdoor into the inside. To do this motive of design, at first solar ray has been tested regarding the incidence angle to secure view to outside. All the circulation from ground level can be reached to the void space through the sloping passage securing accessibility for disabled people. Environmentally, the balcony was projected depending on how much it could provide shading areas.

The motive of the Suseo-dong Community Center is the restoration of Suseo-gyeong. The Suseo-dong Community Service Center faces Gwangpyeong-ro in front, and is located in a position corresponding to the face of Gwangpyeong-ro seen from the end of the street. Accordingly, the existing blocked façade was organized and removed to restore the open view toward Gwangpyeong-ro from the Suseo-dong community center, Suseo-gyeong. Through this, we wanted to create a garden where residents can feel the four seasons. Considering the fact that the proportion of residents with mobility difficulties is higher than other dongs, a convenient circulation line was induced considering the turning radius of wheelchairs. If the façade of the community center is open toward Gwangpyeong-ro, the interior is intended to be a more spacious interior and organized community center by arranging ceiling lights and louver lines parallel to the city axis. For a calm and simple atmosphere, the overall color scheme is gray and white, and furniture in primary colors is placed here and there to induce a lively atmosphere. Considering the possibility of expansion in the future, it was designed by emphasizing the scalability of the front part. By giving the identity of Suseo-gyeong to the existing façade and creating a new garden, it is hoped that the Suseo-dong Community Center will become a comfortable resting place for the residents.

The Suseo-dong Community Service Center was completed in 1993 and is in a state of severe deterioration, which is 23 years old this year. Power outage due to cooling load in summer due to lack of electricity capacity, water leaks in the civil service room and the ceiling of the 2nd floor, malfunction and odor due to aging septic tank, dew condensation in winter due to aging windows, etc. There were safety issues all over the place. Accordingly, the scope of the most urgent correction was calculated within the scope of the allocated project cost.

The first-floor civil affairs office underwent a general renewal, including the replacement of front windows, total replacement of the ceiling and floor, and partial replacement of the civil affairs desk and furniture, and partial renewal of the staff space on the second floor. Nevertheless, partial expansion of the first floor was reviewed to cover the proportion of visits by residents from low-income families and the disabled, which is significantly higher than other buildings, and the increased number of employees, but it was not promoted due to difficulties in securing budget.

Afterwards, in the design process, at the request of the community center, several design changes were made, such as the design of the counseling room on the 1st floor and the entire design of the 2nd floor. It was derived as an optimized plan within the range of not missing.

Under the motif of restoring Suseo-gyeong, a new void was created in the community center by opening a view towards Gwangpyeong-ro, reflecting the characteristics of the community center with an outstanding view to the outside compared to other buildings. Considering the characteristics of residents who visit without a bit of peace of mind, it is intended to function as a spatially calm and open resting place.

Patriotism and veterans begin with not forgetting the past. And the development of the nation is achieved when we do not forget the incidents created by those martyrdoms and work hard. events they made. And the stacking of those events over time. The Seodaemun Veterans Hall was motivated by the desire to become a space that contains the layers of such events. Just like stone stacking, in which the upper stone does not collapse only when there is a solid lower stone, we tried to solve the flow of the spirit of veterans who overcome the pain of the past and go beyond the present to the future with the keyword of stacking events. I tried to implement it in the form.

A city is a vessel that holds buildings, and a building is a vessel that holds people and events. Numerous stories are piled up in the space we live in. As an architecture, this building should be able to become a new vitality in the town of Yeonhui-dong. It should contain new stories and become a space where the future can be stacked beyond the stacking of the past. It should be a space that contains nature, villages, and stories. The motivation for designing this building started from the stacking of the space as well as the stacking of events.

In the case of the southeast side, direct solar radiation (summer 26.5°, winter solstice 73.5°) was applied, and in the case of the northwest side of the main building, where a double skin is currently installed, indirect solar radiation was considered. Normally, horizontal louvers are used on the south side, but in the case of this building, vertical louvers were used overall to adjust the amount of sunlight, considering the characteristics of facing the southeast side and indirect solar radiation from the north side. A double skin was applied to the front of the north side of the office space floors except for the rooftop floor. A thermal mass flowmeter was formed to maintain the indoor microclimate from outside air in winter.

Ventilation in-lets were installed at the upper and lower ends of the facade. Fresh outdoor air introduced into the in-let at the bottom circulates inside and turns into polluted indoor air, which is discharged to the outside through the exhaust in-let at the top of the facade. These ventilation in-lets are applied not only to the front of the building, but also to the entire façade in a ‘U’ shape, so that fresh outside air can circulate from the side.

BIPV was installed on the upper part of the rooftop floor to cover a significant portion of the energy required for building maintenance by utilizing renewable energy. In order to actively respond to future demand, a railing system was introduced to facilitate the expansion of BIPV facilities.

This building is located in a relatively low-density residential area in downtown Seoul. Most of the surrounding buildings consist of low-rise buildings with 3-5 floors, so consideration and consideration for the surrounding landscape are required when the main building is built in the future. Accordingly, an observation deck using a level difference was installed on the rooftop floor for a view of the surrounding landscape. Considering the context with the surrounding environment, a roof garden on the third floor and a rooftop garden were installed on the rooftop to emphasize the character of the green building. To this end, a soil depth of 850 mm was secured, and planting of tall trees was made possible. The plantings planted on the roof garden and the rooftop floor will not only shield the cooling tower and water tank, but also provide a healthy sunny environment indoors.
