Hoping someone can help give me an idea of costs involved. We are in a London Victorian brick built terrace. We would like to open up the rear exterior wall of the kitchen to install bi-folding doors which would approximately make the new opening 3100 X 2280. There is currently a single back door and window. In the past previous occupants have bricked up a door which would have led to a outside access toilet.

We know approximately what the doors will cost but are clueless as to the building cost and process. Any help gratefully appreciated.

Probably at least a couple of grand on top of the cost of the doors?

You need to factor in the labour cost, building regs and structural calls.

Thanks BennyTheBall, that gives me a ballpark figure. Do you start with a structural engineer or a builder?

I'd go for structural engineer as they will identify any issues, such as the size of the brickwork returns which can be an issue if they will be small.
