The story

Down to the garden.

The family had a dark, low garden level they never used. We lowered the floor, extended the rear wall and opened it to the yard with a wide run of glass.

Underpinning and drainage were designed first. Once the structure and the waterproofing were in, the room went up quickly.

Materials

Glazing: thermally broken steel-look aluminum doors

Floor: wide-plank white oak over radiant heat

Ceiling: exposed original beams, cleaned and sealed
