Title: Increasing the height of a planned new build house
Post by buildynovice on Oct 3rd, 2017, 12:12pm

I have permission for a new Chalet style house (bedrooms in the roof with Velux windows).

I've been advised that if I lower the foundations by digging down, it will gain me more height in the roof and therefore more space upstairs. I've heard this from a number of sources, but am not sure (technically) how to go about this.

I am aiming to complete as much of the work myself and would appreciate any advice regarding digging down to lower the foundations.

I assume you mean lower the ground floor to below ground level.

If you are thinking of lowering the floor below ground level I would advise against it. It's very costly and can be problematic in the future. A good architect should be able to advise you how to get the most useable space from a loft room.

You need to be aware that the building regulations require a level entry which usually means no stairs up/down to the front door.

The proposal to lower the foundations/ground floor might work but a lot depends on the terrain. If it's sloping then partly digging into the slope can achieve what you want to do. As could lowering the whole site or a large part of it.

Building a full basement would also get you more floor area but at considerable cost

Another option would be to change from a hipped roof to a gable.

Can you post a link to your plans?
