Advice on approx cost of garage conversion and conservatory

KitKatKate

Hi there,

We want to increase our downstairs living space and are thinking of converting our garage and replacing the very old single pane glass conservatory.

The garage is 17sqm and is currently single brick with concrete floor and flat room, we would want maximum insulation so what do we need to ask for? We would also like a pitched roof with 1 or 2 skylights. Garage door bricked up and window to front, rear to replace window with french doors. How much do you think this will cost?

Adjoining the garage we would then like to have a dwarf wall conservatory 5m x 3m, with pitched glass roof too. We would like to use this room all year round so if you have any advice it would be greatly welcomed.

What sort of price do you think we will be looking at for both of these?

Sorry if there are a lot of questions but we would like to do our research before we have companies come out and baffle us.!!

Many thanks & Happy New Year

We've just had a conservatory like that 5.5m x 3m and it cost around 17K (the price included french doors for the kitchen). We've got no blinds so is a bit chilly (have a very small radiator out there at the moment) but with an oil filled radiator it gets nice and toasty very quickly

Thank Kte, thats pretty much bang on our dimensions so handy to know.
Have you gone for a dwarf wall? Did you use a national company or a smaller independent? I'm thinking of having 2 rads in there. Did you have any special glass for the roof? there are so many choices about

Can't comment on the cost of the garage conversion, as mine was converted to a kitchen so I had additional costs.

However, you will need to comply with building regs and mine wouldn't allow a single skin. I had to have a DPM put in the floor, so that had to be dug up. I also needed foundations digging for the wall which replaced the garage door. Do you know if your foundations will be able to take the weight of your new roof?

Thanks jellie,

I am assuming that foundations are good enough as house opposite has a 2 story extention on their original garage.
Yes the cost of a kitchen can be very costly so understand.
I think we will need another layer of brick inside to form more insulation unless there are alternatives.
Thanks

Yes a dwarf wall and our right hand wall is brick and plaster as it is the adjoining house. We went with a small independent but have to say they have been the worst company imaginable to deal with and it's been a nightmare build - to the point where they put the walls up then called me that night to say they'd forgotten to order the roof, when the roof did arrive it didn't fit so they've had to patch a hole where they measured the brickwork wrong and so it couldn't be made to fit...and the list goes on! :mad:. But the result is amazing (apart from the leaking door lol)...having a glass roof is truly amazing.
I'm not sure which we have but it's the neutral glass (not the blue tint) and I think is supposed to be a self-cleaning one.
I'm guessing it will get very hot in the summer so we have lots of windows with openers to keep a draft moving. Two radiators should help a lot. Ours got warmer once we put down a laminate floor and I'd recommend an oil filled radiator as a back up. Good luck!

There are alternatives. Or rather, there are better solutions for an already built house.

How old is the house?

Hi Doozergirl,

It was built in the early 70's.
