Getting building work done - don't know where to start!

[ADuckNamedSplash]

We live in a 3 storey house. The top floor has a small landing, off of which is a small cupboard and a large room that runs the full length of the house. We want to divide the room in two.

As well as putting in the dividing wall, we’ll need to add a skylight, move the loft hatch, change the ceiling lighting and switches, replace the carpet, etc. There’s a few things that will be affected by buildings regulations (e.g. doorways) and though I’ve done a bit of reading up on this, I’m by no means an expert and not certain how feasible our plans are.

My question is: where do I go from here? I’ve never done anything like this and am a bit clueless! For instance:

• I assume the first step is to draw up plans - will a builder do this, or do I need an architect? Will they just draw up whatever I ask for, or will they ensure everything will be compliant with building regs?

• When it comes to getting the work done, will I need to find and co-ordinate multiple tradespeople for the different types of jobs?

• Do I need to source things like the skylight and carpets myself, or would I do this through the builders?

...etc. Also, if anyone has done something similar and can give me an idea of the cost I’m looking at, that would be very useful!

Buy things like carpet yourself as builders will have no upper hand than yourself.
We had Isence from off line and save loads compared to the shop that was selling it.
If you find the right person they will have a team to do all so you wouldnt need to find multiple to do so

It doesn't sound like it needs plans or an architect. A competent builder should be able to walk through this level of job with you. In your example builder would get the skylight but not the carpets and if you go for a building firm they would get their trades in - chippy to do new door, electrician for lights etc. This may work out more costly. Or not. Building Regs. Usually clients instruct the BCO (can be either private - Google will throw up a few) or via your council. You have to pay a fee and they inspect, usually liaising with your builder. Have you any neighbours or local friends you could get recommendations from as your first step would be getting quotes from local building companies. Also, make sure the quote is crystal clear in what it includes - for instance light switches (usually cheaper to source yourself) and if so, exactly which ones (finish etc).

Thank you both - a bit clearer now, and some things I hadn't yet considered!

A builder can walk you through this, but expect it to be around 10% cheaper if you project manage and use your own tradespeople (if you can find non-VAT registered people, you may save as much as 30%).

I would get advice on things like rooflights. They can vary wildly in price.
