First Time Builder here

[BrainNotYetDead]

Hello from Surrey, UK.  

First time builder here, keen to explore the most efficient and cost effective way of converting my garage.

what is the construction, is it detached / attached to the main house.

 

What are the internal dimensions.

 

one of the biggest hurdles you might have is getting enough insulation in the floor and still having a decent floor to ceiling height.

Hi and welcome.

First off, you’ll need to make a building control application, and that will then mandate the minimum levels ( thickness ) of the insulation you will be required to install.

You’ll need that from your BCO before anyone can advise much further tbh.
