As above. Ideas welcome how to achieve it. I only assembled a garage on a foundation so zero experience in building. The planning permission has been approved. The extension should be around 4m by 5m. The quotes I received are in 40k. Location is West Midlands.

Cheers biggrin

Do as muc donkey work as you can.
Watch YouTube vids and dig your own footings , anyone can use a shovel and spade , even laying concrete foundations and sub floors are easy .
I’m in the middle of one myself .

Get someone to do the structure and you do the finishing.

Finishing is where the time is and if you are handy and have time yourself its possible to do most things.

Cheers. I will look into it. Thank you for the heads up. My garage is a bit of a flop so don't want the extension to be in a similar state. I will see where I can save a little.

Make sure you know what BC will want in terms of insulation etc as this often catches people out.

Make sure they come and see it before you cover it all up!

Very true, but finishing ialso needs the most skills if you want it to look decent, for example plastering, there is only so much rough plastering you can hide with paint.

We recently finished an extension and I got involved as much as I could with the build, more out of interest than anything.

One tip, set up an account with you local builders merchant and allow the builder to order materials, that way you get the discount on materials and don’t pay any (possible) mark up if the builder suppliers. This worked really well for me and as it happens I still have the account and get a good discount on stuff I continue to buy.

As another poster said, beware of extras! Make sure you are very clear on what you want them to quote for - for example for mine I had to pay 3rd party inspector not the builder. You haven't said if single level - if it is, consider a roof lantern, best thing we did. I had them build the structure (foundations/walls, windows, roof + doors and level floor) then I did the internal ceiling (insulation/plasterboard), all electrics and plumbing, walls (plasterboard) and floor (tiled). Also consider UFH at this point (we decided not too as a lot of glass in the space).

Similar size to yours, price was 23k for the builders work, prob 6k of my work (inc BC). Surprising how the little finish bits add up but it does depend on finish.

As above, buy materials yourself via a trade account at the local builders merchants.

We did our extension with a local builder who charged a day rate, and I bought all the materials myself and paid subcontractors direct (scaffolding, electrician, plumber and plasterer - all the builders contacts).

Did doors, skirting, decorating and floor myself, as well as making sure all materials were moved to where they needed to be before the builders turned up, which due to our access issues was a mission in itself!

Managed to get a 5m x 5m double-storey extension done for about £50k all in (apart from my time). That includes carpets, furniture and the retaining wall/patio, which was a big job in itself.

Re-used windows where possible (repositioned them and painted).

From this...

Looks very good. It is a single storey, we wanted a longer than 4m, but were refused.
What does BC stand for?
How would one find a builder? Those builder websites seems to be a waste of time to say the least.

This looks great. I assume this is a detached house.

And why are the radiator pipes on the surface in a new extension?
From what I can see it looks a right bodge.

BC building control

We found our builder by local word of mouth recommendation.

Um because it is my extension and I wanted it done like that?? I like the look when the copper is polished. May not be to your standard but nothing was a bodge. To add, this is a thread on extensions on a shoe string, not powerfully built PH director style constructions. Not that I bit at all biggrin. Its also not the full picture, the other half being more industrial look with exposed metal beams, upright rad, glass panels and wooden walls but I've decided you are too rude to see that biggrin. Only this part of build applies to OP though.

To OP, I found a builder by asking work colleagues for recommendations, was able to view the work a builder had done for one of them. BC...building control.

Cheers for the replies. I did have a few builders come, but they did not look very reliable and/or experienced. Maybe, I am too picky. biggrin

I’m curious o know what a reliable and experienced builder looks like ?
A guy in a van and dressed in scruffy work clothes but who can read a set of plans is usually your best option .
You said your looking to do it cheaply , don’t get fixated on the financial side if your not willing to get stuck in yourself .
There’s an old saying in the building trade , it’s about monkeys and peanuts .

Someone who can turn up to an appointment on time. There were folk asking if they should get a quote for foundation made as that wasn't part of the quote. Also there are lots of "managers" who give a quote and then get contractors to do the work. I don't think good builders are short of jobs.
It was similar to roof tile replacement quotes until I saw a work done at nearby street and enquired the owner of whom he used.
