A floor contains several layers. Its finished height affects doors, stairs, kitchen units and transitions.
What the drawing needs to explain
Draw sightlines from two seats and show shading positions. Review the same layout in daylight and with interior lights on; privacy works differently in those situations.
Agree a reference level
Use one datum for everyone and record existing and proposed finished heights. Rough construction dimensions are not necessarily ordering dimensions.
How to review the result
Check the view at seated height and operate all opening elements. Review whether shading and lighting provide the intended shelter without obstructing everyday circulation.
Which trade-off matters?
More glazing does not automatically make a better room. Compare continuous glass with a combination of glazed and solid wall areas so views, furniture and shelter each have a place.
Questions for your own property
- Are finishes included in heights?
- Do doors and stairs still work?
- Are all floor layers known?
