Extension - how?

[dfen5]

Thinking of getting an extension on the rear of the house. It's a chalet style house (steep pointy roof) so I want a single story extension, about 4' deep x 16' across. One wall on the left is there already (garage/rear door/out buildings) and I want the roof to follow the existing roof and then drop down to the existing wall.

Fantastic drawing below, planned extension in yellow..

What's the first step? Gat a drawing, go for planning, get a quote or quote, plan, planning, build?

Any ideas what the stages will cost and care to take a guess at the overall?

Is it worth it for only 4 feet?

Surely that's a pointless extension? If that's 4 foot overall length you're going to have about 3' space max allowing for the cavity wall. That can't be worth it?

Assuming you have no other extensions on the house you may be able to complete that under Permitted Development (ie. without planning permission). Check the rules (Google is your friend).

You'd need plans and to comply with building regs. Once you have plans you can get quotes, then you need detailed drawings for the builders to follow. Also what's to the left of your property? You may have a Party Wall notice to serve on your neighbour.

Best course of action is to chat with an architect. PHer campfreddie (Haus Design) is your man.
