Cost of side return extension

[SurreyisSunny]

I’ve just had my first quote through for a side return extension. I live in a small mid terrace house in Surrey. The extension will not be big but will make a huge difference to the house.

First quote excluding a kitchen, doors, flooring and windows is £60k. Another £11k to move the bathroom upstairs and remove chimney breasts (again excluding bathroom fittings). I also need to pay to rewire the house. If I spent this much i would have spent more than the house will be worth after the works are done.

Does this sound reasonable?

It’s hard to know without knowing the details (size of steels, whether you are moving drains, amount of new roof, etc) but it sounds pretty punchy - like London prices. Have you worked out the price per square foot? You’ll find useful rules of thumb about it online, often by area of the U.K. Do get a few more quotes!

Side returns are horrifically expensive for the amount of space you get - but they can make a big difference to how useful the space is.

I’ve got 3 more quotes to come so I’ll have to see.

It’s not a huge job but a lot of steels (4) and one drain to move,

I’d budgeted £50k all in. My neighbour did full house incl side return for £60k but this was 4 years ago. She had problems with her builder so can’t use the same

£50k all in sounds on the very low side.

I had my side return done 3.5 years ago. It cost £80k including the building work, underfloor heating, bifold door, windows, tiles (cost of tiles + labour to lay them), kitchen units, painting & fitting everything.

I think we paid around £60k just for the shell (construction; bifold + 3x Velux windows).

It’s about right but obviously not cheap. If you’re planning to stay there and not move, don’t worry about what it adds in value providing you can afford it: it’s your house and enjoying it is so important

Our fairly small extension including a downstairs shower room, utility cupboard and new kitchen (with a lot of cupboards!) Cost £70k. That was everything including bifold doors, flooring, and 4 new internal doors. And a 20% discount from a DIY store for kitchen, shower doors, sockets etc

Thanks all

Had 2 more builders around yesterday so will await their quotes. One gave me a ballpark of £90k. That plus kitchen, flooring and bi folds seems huge. I have decided to scale back the project now as realise can’t afford to do it all.
