Tiny extension!

[ThisMustBeMyDream]

My kitchen is tiny. I need a new kitchen as it has fallen apart. So I now need to decide if I should extend given the need to replace the kitchen. I've always wanted to. But the cost and the practicality of the extension has put me off. The house is a typical 30's small semi. The original kitchen has had a small 1m x 3m extension. I want to extend it by 1.5m. So it will be a 4.5 sqm extension.

What kind of cost am I looking at for just the extension? I've been told the rsj is in place from the previous extension. Do I really need an architect for such a small extension?!

Help! See pic of stupidly small kitchen for a family of 5! (Pic a few years ago before several of the cupboard doors fell off, and 2 more kids were added to the household. It is far more cluttered now!!).

Ooops, forgot to add. I'm in NW England. Not an expensive area.

Normally they say £1-2k per metre. However, my friends have all found recent quotes never below £2k when everything added in. In addition, a small extension like this will be higher just because of the standing cost of getting kit on site etc.

Oh...just because here is an existing RSJ, don't assume it is fit for purpose. Our house had a lot of work and needed new steels....we found one of the existing steels was in fact a wooden post which had been wet when out in so had swollen and when dried out had left a huge gap....the blocks were virtually self supporting!!!. Friends have found existing steels undersized so then had to have them replaced.

Frankly if you have the space you might be advised to look at the options to go bigger and get more value out of it

Our existing steel was undersized....replaced one with 3....

Building expensive and long lead in time everywhere.

We got plans drawn up as the drainage was difficult, conservation area, old house and we ended up going bigger. But for something like you are thinking we were being quoted around £70 k not including kitchen. Expensive area though and having 2 sets of sliding doors and a roof lantern.

Think about light and windows and how to get light into the rest of the house.

Also might be worth going a bit bigger if it means you could have utility or downstairs loo. I put a floor pan on here and got some good ideas.

There isn't the space to go bigger. The garden is small. The room to the side starts at 1.5m at the front door but narrows to 1.10m by the kitchen. Iooked at planning applications and our neighbour 3 doors down was refused planning permission to go to 0.1m to boundary. It stated it had to be 0.8m away because they don't want our road to look like terraces 🤣🤣🤣🤣🤣🙄🙄🙄🙄🙄.
I'll be having 2 chimney breasts taken down and driveway and garden done at the same time, so might soften the blow to a builder perhaps?!

That is the planning application that was rejected. Looks like they built it anyway as they never had one passed and it is definitely built like their plans are!
