This box-shaped steel house, hidden in shady green woods, has a cool, peaceful resort atmosphere. – hard to believe it’s right in the middle of a congested city!

Designing architect Boonlert Hemvijitraphan of Boon Design took up the challenge set by the owner: create a home on the limited plot that is neither cramped nor stuffy.

Boonlert said, “The challenge was to make that work within the urban context. Fortunately, the owner gave us a completely free hand; our job was simply to design a comfortable residence on a 360-square-meter (90-square-wah) property. The starting point was what we saw in the original landscaping here.”

The property was not large, and its location right in the center of a capital city was seriously limiting

How to build a comfortable residence here? The garden/orchard greenery was used as a tool to create a sense of spaciousness.

Instead of the house spreading outwards toward the fence, it rose vertically as a 2½-storey home with open space beneath the house used as a carport and multipurpose area, the rest of the property becoming a relaxing, park-like space.

High-ceilinged living room, naturally bright and airy, with a great view of outside greenery.

The large garden was set up to the south to get the best breeze and the best shade from plants and trees.

The garden is planted on soil raised 1.2 meters higher than before to be level with the 3-meter height of the living room.

The living room connects with the dining area beneath the mezzanine, with the kitchen behind the glass door
The metal bookshelf reaching almost to the mezzanine also acts as weight-bearing support for the staircase behind it.

The first floor has a high “double volume” ceiling for more natural light and ventilation. A steel staircase rises from the living room to the mezzanine, which holds a workroom and guest bedroom, and up to the second floor, the owner’s private space.

The single staircase up from the carport connects everything from the ground to the top floor.

Mezzanine walkway with banister and protective grating steel is the primary building material, but natural materials such as bamboo are also important.

Bamboo shades cover the house façade, filtering sunlight, protecting against rain, giving privacy from outside view, yet still allowing good ventilation.

“We used steel not because we especially wanted to use steel, but because it was light, and we wanted that quality,” explained Boonlert.

“Each material has its own particular value. Coming up with a principle means coming up with the quality we want. Design is a value in itself.”

The architecture of this house reflects modern times. It’s surrounded by the natural environment people long for, so no matter chaotic and confused the outside world, in this home there’s a mood of relaxation and contentment: it’s just a great place to live.
