Garage conversion

[Twospaniels]

I know this is probably a ‘how long is a piece of string’ question, but thos of you who have converted a garage i to a usuable room, approx how much did it cost.

Our study is next to our integral double garage. I would like to use half the double garage and knock through making the back end of the garage into a wet room and the front part of the half garage combined with the study to make a bedroom.

I converted my internal garage 18 months ago.
Made a semi self contained annex. The bedroom is 5x4 metres. At the side their is a small lobby with front door and space for coats, shoes and bags approx 1.5 x 1.5 metres..
Big window at the front matching the other house windows. Back of the room is another small lobby with door to small shower room with sink and toilet and heated towel rail.Access door to the utility room and the main house.
I had a raised floor, dropped ceiling, 2 radiators added to the house boiler, shower added to the water system ( more expensive than putting in a power shower but better water pressure). A new ring main with 2 ceiling lights in the room, and a light in each lobby plus a total of 6 double electric sockets plus outside lighting.
All completed ready to decorate came in at £18k and that included the building regulations. I am in the south east and the work took just over 6 weeks.

We converted nearly all of our double garage into a games room and had our hallway/front of house entrance extended to allow for the internal door. Around 25k with electrics. East of England.

Watching with interest! It sounds very expensive Has anyone did it themselves and got it signed off by a Building Regs inspector? How much did this roughly cost?

Watching with interest as we’re hoping to do that this year. Double garage to double storey conversion.

We had a single garage that we converted. It has a room above it so we soundproofed and fire retarded the ceiling, added a small toilet room, radiator and spotlights and got rid of the garage door to make a window and external door. It already had plumbing and electric as the washing machine used to be in there. Cost about £8000 using a garage conversion company who did everything. The only thing we didn't add was an internal door as there is nowhere in the house it could have gone due to layout. We are in Midlands

We have a similar sounding set up to you - study then double garage. We had half the garage converted and a doorway knocked through to the study. No plumbing or anything, our new room is a dining room.

Had this done just before Christmas. Cost us £13.5 including having laminate flooring fitted in new room, study and dining room. Had the back door of the garage moved as part of the conversion, it was moved to the back of what is now the single garage.

We absolutely love our new room, so glad we had it done. This was the middle quote we had, cheapest was about £12k but was going to take 4-5 weeks. Ours took 2, and was a specialist garage conversion company.

It's currently being decorated, along with the rest of the house, and is looking gorgeous!

We converted our integral garage into 2 rooms (study and utility room) last year and it cost us £13k excluding the kitchen units. We’re in the South East.

Has anyone converted an external garage? We are thinking about doing a part-conversion of one to office space and leaving the other half for storage. Wondering if anyone has tried that and how much this has cost them roughly xx

[PolarnOPirate]

I'm amazed at some of these costs. £8k?? I'm guessing that involved a proper roof, walls, insulation, heating etc? I would have expected much higher!

[PolarnOPirate]

Ah sorry re-read, there was already a room above that £8k garage so no roof needed ?

We were pleasantly surprised with the cost too! Yes, we just needed some sound and fire boards put on the ceiling as there is a bedroom above. I think they added a bit of insulation to the external wall and did something to the floor to prevent damp. The toilet was an easy job too as there is an on suite above the garage so they were able to plumb the toilet into that waste pipe as well (or something like that!) they added a radiator and extra lights and plug sockets. I'd budgeted in my head £14 thousand so I was very happy. They even laid the lino flooring for us.

Hi, I hope I am not repeating something already said. I am planning to convert my single garage into the dining room and joining it to the kitchen via an opening of around 1.4m or so. My doubt here is if this new space would be too narrow and look like a corridor... I'll see if I can attach a basic drawing but roughly one end is 2.7 m wide and the other is 3.5 m wide. Length is just over 7 m. :-)
