DAUGHTER’S FAMILY
This is a typical medium size of apartment in Seoul, where a parent lives with three grown up son and daughters. The years passed by, they became 8 people after the eldest daughter’s marriage with two newborn babies and husband.
The apartment soon became very busy and uncomfortable, especially for elderly parents who recently retired then spend more time in the house and children who started to running around at home. They started to think about having quiet and relaxing living where elder parents can enjoy spare time, also children can play around the yard away from a busy urban apartment lifestyle.

The site is one of the residential town, 15 minutes away from the city center Seoul. Unlike a rural suburb there are fully equipped infrastructures, good educational environments and amenities. In one word this site is a popular place where one could pursue not only a comfortable suburban lifestyle but also having the full convenience the city has. However it is a pity this area has lack of public space such as a promenade and park because of dense buildings and monotonous street scape.
6
The new place for the family is located in the spot for the far northeast hem of the Guemto Mountain. 17 by 13 meter site facing road directly surrounded by built or to be built neighboring houses. Only 2 stories below 220m2 allowed for the new house.

The first idea was to make one big space where they can share their life all together without any boundary. So we imagined to make a huge room in a yard where all the family member communicate, eat and sleep together.

However, as time goes by, various demands about house began to come out.
Grandfather wanted to have a his study and a kitchen garden. The wish of grandmother was to have a large kitchen and storage room. Uncle and aunt wanted their own private space. Mother needed plenty of storage space and secondary kitchen and father needed separated family room and his study. Bedroom and playground for two children as well. Additionally including bathrooms, living room and dining room, finally the total number of rooms became 17.
Usually for similar size of apartments, there are about 10 rooms. Then how can we make this many rooms to be happening?

How it is possible that all family members stay together, meanwhile keeping privacy at the same time? Some ideas came up as follows.
-How about a house with a large front yard? -How about a house having a small garden overlooking living room and rooms? -Isn’t it attractive to devide the house as per each generation like duplex? -How about making a garden more useful by separating front yard and back yard? -How about a house having a large living room enclosed with a yard? -What if the living room is on the second floor with a large terrace?

An idea emerged throughout these studies. The idea is to make courtyard at the heart of each floor so that diverse living spaces are continuously unfolded around it. Thus the house is completely open-up and each space is interconnected through the patio which embraces abundant daylights and nature deep into the inner spaces. Every single room is configured to have a terrace which can link another room as spatial extension. And the large roof garden evoke diverse programs of living with nature as an alternative solution for small site which is hard to maintain privacy.

Squarish land is divided into two compartments with a void in the middle to allow better daylight condition for the rear side. Two southern aspect houses, courtyards and services (IE. stair and kitchen) link spatially and physically those two compartments. Basically it’s two story house, but actually looks like three floor with its carefully designed stair case with skipping floor.

The house facing the main streets looks taller than other two storied houses around it due to the roof terrace. Facade shows innocently the outline of the roomâ&#x20AC;&#x2122;s configuration with minimum openings for daylight and ventilation made of transparent or opaque glasses protecting the privacy from the street.
29
Fruit trees and flowers will be planted in the side garden in the spring after this winter. View from the dining room and roof garden will be full of colorful landscape.
30
Here is the main entrance. Some inner spaces are slightly visible through windows and gaps. Letâ&#x20AC;&#x2122;s walk into it.
31
32
There is a living room with a sofa and dining table as you pass the entrance. Through the double height window facing with courtyard, you can see the terrace of the second floor in the courtyard with abundant sunshine. Small window on one side of the living room is connected with playroom. When the window is opened children can communicate with other families in the living room.
33
When youâ&#x20AC;&#x2122;re sitting on a sofa in the living room, you can resonate with the nature through the patio which doesnâ&#x20AC;&#x2122;t have clear boundaries between inside and outside has a different attraction with the front yard.
34

36
Patio surrounded with hardwood which has a warm and cozy atmosphere with the blue sky is another micro cosmos differ from the outside world. Staying outside of noisy urban life, you can find peace through meditation and contemplation in there. Also this is the place where all the family can be united and communicate with.
37
Here is the bedroom for grandmother and grandfather facing the living room through the patio. Space changes dramatically as you open the window on a fine weather. Grandmother enjoys the courtyard with the diverse scene of life such as planting or drying crops.
38
The Study is next to the bedroom for grandfather where usually writes. It is very silent and cozy room which is hard to believe that the road is very next to the noisy road.

Wide steps are extension of the living room where children can read, play and also family can watch the film with screening wall. Then letâ&#x20AC;&#x2122;s go to the second floor.
41
42
Room for aunt which has study and bedroom area has scenic views on both side. She can enjoy the scenery of distant mountains, also play with children on the terrace. Extended inner space with terraces make small room boundlessly.
43
44
There is a balcony which connects the auntâ&#x20AC;&#x2122;s room and uncleâ&#x20AC;&#x2122;s room. It is unique there is no corridor in this house. Instead every room has each exterior platform so that rooms are connected through it.
45
46
A childrenâ&#x20AC;&#x2122;s room facing the second floor terrace is a duplex. The upper part is the study room connected to family room and below is play area which has a window to the living room. Children love to play with their friend on the terrace. It is hard to imagine from outside such large terraces are superimposed in a simple box shaped house. These abundant multi-functional terrace can be used by both independently and unitedly.
47
48
When you are going up another half story there is family zone for children and parents. Because of the double height of the below living room, this zone became a half floor higher than the opposite side which makes whole interior spaces continuously flow. Terrace and roof garden can be visually connected at one sight through mini kitchen over the half story below from the family room.
49
Parents wanted to have a large bookshelf to fill rooms with many books and a big table to read, write and draw with their kids.
50
Master bedroom with traditional Korean paper screen doors makes the flexible conversion of a family room into a bedroom. Itâ&#x20AC;&#x2122;s so beautiful when warm and soft light is infiltrated through the screen.
51
Additionally, two lofts are used in each as studycum-hobby for father and storage. There is full with a natural light from the translucent roof.

54
A panorama picturesque opening on the roof terrace frames the beautiful scenery of Geumto Mountain. Changing of seasonal scenery like spring blossom, flesh verdure, autumn leaves or winter snowing makes life in this house more so colorful.
55
This is the story of the Pangyo house. At a small site surrounded by neighboring dense urban houses in the middle of suburb housing town, the house contains 17 rooms for a three generation 8 person family with various outdoor platforms which are configured/organized carefully for mutual connection, spatial extension and day lighting. Just like so many town squares, multi layered terraces in the heart of the house used for common gatherings or as for a stage which can be filled with various living scenes as per constantly changing nature. At the same time as if the streets, it connects the rooms for diverse spatial extensions and defines altering the relationship of dweller as well Very simple yet strong attraction of a patio house has been, different from defining and limiting way of composition, it endlessly enables, embracing and extending beyond its physical boundaries. The emptiness in-between is not absent, but a potential field which is dynamic and responsive to accommodate a broad range of fixed and changing activities of creative life of the dwellers.

7. ECONOMIC FACADE MATERIALS
As a building material, stucco was traditionally used as both an interior and exterior finish applied directly over a solid masonry or stone surface.Durability and breathablity are the major sustainability benefits of cement stucco. Stucco is a water-shedding, hard, impact-resistant, fire-resistant, and color-retentive, exterior finish material. 64
Inner facade wood cladding material is made from bundle of leftover SPF wood which have moderate strength, are worked easily, take paint readily, and hold nails well. Itâ&#x20AC;&#x2122;s left over material thus extremely cheap and natural irregularity makes quite an interesting pattern and shadow.
