Loft Conversion / Lowering Ceiling

[TheJammyOne]

Hi all,

I need a bit of help or advice regarding my predicament with our loft please. After a very long while being in the market, we have finally purchased a property in the Mitcham/Streatham area.

It is a terraced property that we would like to have a dormer loft conversion done.
The issue we have is that currently there isn’t a lot of room in the loft space. We had an architect come round and take some measurements. The architect has informed us that if we were to proceed with a loft conversion, the first floor ceiling will have to be lowered.

Currently the ceiling in the first floor measures at 2600mm. To achieve a finished ceiling height of 2000mm in the loft, the ceiling will have to be lowered by 300mm. This will lower the ceiling in the downstairs bedrooms (2 double, 1 single) and bathroom to 2300mm.

The plan would be to have a master bedroom with an ensuite in the loft.

My partner and I aren’t very tall. I am 165cm and he is 175cm.

Would it be an unwise decision to go ahead with that level of work?
Not that we have any plans to but would it be difficult to sell in the future if we made those changes to the property?
Has anyone lowered the ceiling to 2300mm or similar, is it something you’d recommend or avoid?

We would be grateful for any help and guidance on this please.

Thanks in advance!

I wouldn't. Can't you get to at least 2400mm in the middle floor? That's a modern standard. Personally I hate ceilings lower than 2.5m, but I'm fairly tall.

Thanks for your reply. Unfortunately no. In order to achieve the 2000mm head height in the loft, the ceiling would need to come down to 2300mm.

Are you sure you wouldn't be able to raise the ridge height? I'm in Wandsworth and we raised the ridge height in our planning application which gained us a decent amount of head height in our loft conversion

Doesn't sound worth it, likely cheaper to move.
