1) Concept:It is our main theme to establish a fine connection between the exterior space andthe interior space when we design plan spaces and comfortable places for the house.It is our first priority to create a new environment where the building and theexterior space of the site have a kind of togetherness in the local environment.
Wecreate an environment that is designed especially for the house. Our design thatestablishes very smooth life styles between the exterior and the interior spaces,will offer a living environment where windows can always be kept open, withoutshutting the curtains all the time.
This will make the house that is energyconscious yet comfortable enough to maintain the fine thermal environment for theresidents of the house.However, this environment and energy consciousness may bringup the issues about the security and the privacy of the residents.To achieve the idea of making a house that has a good connection with the exteriorspaces, there are two ways of designing a house.We can design the `space` (eg; openings, secondary parts such as paper screens orshutters) or, we can design a house which includes private `outer space` such ascourtyard.,To choosing which one of the above two ways, depends on the conditions of the site,environments of the area, budgets and so on.
This particular `House in Kamogawa` wasdesigned in the later method that has a private courtyard made especially for theresidents of the house.This site of 250 tubo (approx 825 square meters) once was a bowling alley and thenit had been kept like an `open land` or `idle land` where we used to play around inmy childhood.
There is a shrine connected with children`s park in the southern sideof the site. Thus the area gets busy with lots of families visiting the park onweekends and holidays. Also, the site faces residential houses and apartments allaround. The client is a family of 4 members: husband, wife and two children.
As theyare used to live in a quiet apartment before moving in to this house, they firstpriority was to have a very privacy conscious and very security conscious house.To realize client`s needs – high consciousness for privacy – we designed with astructure of a one-storied, 40 tubo (132 square meters) house which is built aroundthe square shaped courtyard.
The design presents closed exterior and the interiorspaces opens towards the courtyard only.By this circuit floor plan around the centrecourtyard, the wall that is inclined inwards and slopped ceilings along the gableroof, the interior creates `opening space` even though the plan is made `inwards` tothe courtyard.To create smooth and continuous movement of the residents beyond the border of thecourtyard and the interior spaces, we designed the opening that is fully open to thecourtyard.
And to achieve that, the house has no structural wall. We usedsteel-frames around the centre-courtyard and wooden column-frames.The house is surrounded by wall looks like `a closed clam shell` and that is tosecure privacy of the residents and to maximize the security of the house.Theexterior of the house presents different shapes from different angles, however, itis quite a simple structure with gabled roof with ridges used diagonally against thesquare shaped land.
By doing this, we believe that the design had achieved to offerthe very efficient interior spaces with descent workability and cost performance.Even though this house is open only towards the courtyard, the courtyard is notworking as an amenity `in the house`. This house has achieved to have a very richrelationship between the interior and the exterior spaces.2) Structure of the house:Around the courtyard ? we used iron-flames.
We plan the overall structure with the up beam across the scaffold. Scaffold is set up with 76φround columns and 200mm×90mmC shaped steel.We used 60mm×210mm timbers for both sides of FB19mm×200mm corner block considering the weight pressure and to settle the corner blocks in the same style as the up beam..
