Height changes more than atmosphere.

Floor height changes the feeling of a room, but it also changes walls, stairs, windows, services and the volume you need to cool.

Higher is not automatically better. A tall room works best when its width, windows and furniture also suit that height.

02 Options

Choose a proportion, not just a number.

The height should make sense with the room's width, openings, lighting, furniture and purpose.

10 ft

Efficient

Comfortable in normal-sized rooms, with lower wall area and enclosed volume.

11 ft

Balanced openness

Noticeably airier, with flexibility for taller windows and lighting.

12 ft

Strong presence

Spacious and dramatic, but adds wall area, stair rise and cooling volume.

13 ft+

Grand scale

Best in deliberately tall architecture; it can feel excessive in narrow rooms.

03 Clear

The quoted number may not be the height you see.

A quoted floor-to-floor number is not always the height you finally see.

Floor-to-floor height compared with finished clear height after slab, beam and false ceiling
Ask before approval
Is this floor-to-floor height or finished clear height?
  • How much remains after the slab and beams?
  • Does a false ceiling reduce it further?
  • Does the staircase already account for this rise?
  • Do the window sizes still suit the final room proportion?

04 Lab

Move from 10 ft to 13 ft.

Watch how the sense of openness arrives with more wall, stair rise and enclosed volume.

Principle

Taller can be betterβ€”when the whole room is designed for it.
