Increasing height of dormer first floor

GoneShootin · 21-05-2009 3:31pm #1

At the stage now where I'm trying to maximise the height of my dormer build for upstairs. I'm thinking of an extra course of blockwork post concrete slab but this will increase the height of the soffits from the ground - so might not be as nice to look at as keeping the roof in line with downstairs wall height.

Any other options I should be looking at?

Assuming A is what you got . B - you don't want .

C. Extend the overhang

D. Crank the roof pitch

Raising the wall plate level to create more usable space in the roof will increase your ridge height. This will be a breach in your planning permission!!

Thanks for that sinnerboy - puts it into perspective.

I'm just going to gloss over that comment pseudo-tech

Attached is one example of where it was done, but in my case it would be 12 to 18 inches over the soffit of the porch, so perhaps bringing the overhang down to at least meet half way might do the job.

Just a point GoneShootin, I would make sure your supervising architect/AT/engineer is ok with this for signing off on. I have come across a lot of cases where the client took it upon themselves to alter building designs and then can not get them signed off.

That's fine but I hope you don't have to alter it later!!

Best not "gloss over" it GS . They guys are correct . Get the ok from your signing off professional .
