Many of the enquiries we receive relate to the cost of building a garage. What if you already have an unused garage and want to convert it into accommodation and useable living space? A garage conversion is a cost-effective way of providing more family bedroom space. A standard single garage will give you around 14m2 extra room. You could put that to very good use as another bedroom, a multipurpose room, a new kitchen, child's playroom, home office space, home gym…there are lots of options. Garage conversions tend to be much cheaper than a loft  conversion or building an extension, especially if you’re currently only using your garage to store junk (guilty!).

Consider having your conservatory converted......this will add an instant room to your home, usually at the side or rear of your lounge area...........call 321conversions for a quotation.

HOW MUCH DOES A CONVERSION COST?

As ever, the final cost will depend on where you are in the country, the exact specification of your existing garage and the space you want to create. However, as a guide, a standard single 321 garage conversion will cost between £10k and £15k. If you add a kitchen or bathroom to your project, the costs are likely to go up, depending on your tastes and feasibility of the drainage work involved. Also check your roof covering outside to ensure its sound and waterproof before work starts.

Compare that to a 3 x 4m extension which could cost upwards of £24k, and a 321 garage conversion begins to look like a very good option.

321 Conservatory conversions are also an excellent way to increase the re-sale value of your property and could cost you from £12k up to £25k depending on whether you just want your roof upgraded or a full conservatory removal and re-build.
