Extension roof advice

[JonHeath]

Hi all,

I'm planning a 2 storey extension on the back of my house. If you see the attached picture then the extension I'm planning will replace the lean to conservatory. My intention is to pull this down and replace it with a slightly deeper extension which will measure approximately 5m wide and 3.5m deep.

I'm at the planning stage at the moment. My question relates to the roof. As you can see I have a few different roofing segments at the moment. If I build this 2 storey extension then what is the best way to make this merge with the current roof?

I want to make it fit in with the existing roof, but want to keep the effort to a minimal as I'll be on a tight budget. I'm not bothered about using the void for storage as I have plenty of that in the existing roof.

As the existing roof won't span the new width of the back of the house at a two storey level I just can't picture how it would look. What would be the suggested roof design?

Cheers
Jon

It would be a hipped roof on the extension, the same as the main house.

Thanks Woody. Would that be a hipped roof in it's own right though or would the roof on the main house need modifying too?

If the sizes work out just right, you could possibly join the two

Thanks Woody for the pics, I appreciate the your efforts. Out of interest which software are you using to generate them?

I'm not sure I can join them as you've suggested as they'll still be part of the house which is on a single storey. I probably didn't explain that very well in the first place.

The bit I've circled in red I'm planning on leaving as it is. I've toyed with the idea of bringing the bit I've highlighted in red up to two storey as well but think the foundations won't be up to standard to support a second storey so it would send me over the edge budget wise.

So if I was leaving that bit single storey how would the roof look?

You can leave that single story bit there, and just adapt the roof to the new extended walls

The software is sketchup pro

I've just realised that your drawing was spot on and it just didn't include the front bit of the house which is irrelevant anyway (probably because I haven't included a picture of the front).

How much roughly do you think the roof on the extension would cost?

Cheers
