Garage conversion costing

[traumaqueen]

Has anyone converted their garage and how much did it cost?

I've had a quote from a garage conversion company and know it is expensive but paying the price for convenience. I am just trying to work out how much of a premium. So any information helpful.

gosh, it really depends on what you want done when your planing on putting in a window or wall etc and what level of finsish you want what have they quoted and for what?

just trying to get benchmark for basic conversion - window at garage door end, insulation/plastering etc.

I had a look at this website. It would seem that garage conversion companies do charge a premium.

I am having mine done but it is a double garage which already has a steel lintel in the middle so that reduces the cost for mine. Mine is being done by a builder (I have seen his work and know him really well) So I will have 2 windows, a store room created at the back of the garages, door knocked through from house, window bricked up in garage, insulation on 2 walls as they are single skin, insulated floor, laminate flooring, lighting, alarm sensor moved and new one in etc etc, (I am having new laminate laid in my hall & dining with new skirting at the same time) £12k

For a single garage conversion my builder had said to budget £8k, that is for everything done except decoration. (I am in West Yorkshire)

Thanks Fizzy, that's what I thought was reasonable for the basics.

Our job includes getting planning consent and doing drawings and building regs, taking out a loadbearing wall and putting in a new RSJ, putting in a dividing wall, and plumbing. BUT the quote is £17,500. Which I think is pretty steep even for Surrey. I know I'd be paying for the convenience and the guy who runs the local franchise has an excellent reputation but TBH i'm perfectly capable of managing this with a builder and don't think I can justify the luxury of a package supplier.

ous cost about £12k to convert into a downstairs tiolet and utility room including planning app and structural calcs/ drawings

We need planning but that is because our permitted development rights have been removed by the council (our house is 10 yrs old) so planning is free! Normally £150.

Building regs is about £350 here and then the architect is about £500 I think. All in all I budgeted £1k for architect, planning fees and building regs fees.

Looking at your costing I think it is a bit steep but then unless you know a builder you can trust what else are you meant to do?

Are they willing to break the cost down for you? I know my windows if plain upvc white 1700 wide, 3 pane with 2 openers would be £250, so you see I know how much my component parts break down into. See if they will give you an idea of what costs what. I know that if I come in under budget the builder adjusts his costs so if it costs £11k I'll pay £11k.

The RSJ or UB (universal beam) will cost a fair whack and you will have to have a structural engineer to calculate that.

stoppingattwo did you already have drains there to connect into or did they have to dig new ones?
