Decide which corner is worth building around

An L-shaped vanity can connect two useful walls, provided the corner helps the room do something it needs. In Drumoak, the fitted furniture runs around the corner in a room with an angled wall and roof window. A large walk-in shower has a clear screen, so the furniture and the room’s roof shape remain visible from the washing area.

On a similar project, draw the corner as two elevations and check where you can comfortably stand to use each part of it. Work out what the return adds to the basin position, then test the same room with a straight run and see what would be lost. Include the roof angle and window position in the comparison. The value of a fitted return is the useful surface and storage it contributes at the right height. A room with unusual geometry benefits when those elements follow the space you can actually use.
