A garage conversion can add up to 10 per cent to the value of your home and give you valuable extra living space that's less prone to planning complications. We can convert a garage into a variety of rooms including living rooms, bedrooms, bathrooms and kitchens. Garage conversion costs are significantly lower than those associated with an extension because you will save money on laying new foundations and building new walls; your garage may also have power and perhaps even plumbing already, both of which will reduce your garage conversion’s cost.
