Typical extensions to Victorian dwellings create a narrow, elongated ground floor that makes it difficult to light the space. To avoid this problem, the Allison House has a double-height ceiling.
The lower part of the ceiling corresponds to the level of the floor above, whose floor slab is suspended, while the upper part of the ceiling corresponds to the height of the railing of the terrace above.
The result is a living room with a friendlier proportion that allows a large window to open onto the rear courtyard, allowing sunlight to flood into the back of the room.
