Case Studies

Loft conversions are a truly incredible addition to any home. Not only do they add vital square footage to your liveable space but they do so without having to sacrifice any of your outdoor garden areas. They can add up to 20% to your property’s value making them not just a great addition in terms of your lifestyle but a great investment. 

Here at Clapham Construction Services, we provide a free consultation for anyone looking to add a loft conversion to their home. During these consultations, we inspect your property to establish whether it’s suitable for a loft conversion while finding out more about your style and what you’re hoping to achieve. It’s also incredibly important, however, that during this time we introduce ourselves to you as a company. The fastest way to get an idea of what we can help you achieve is through looking at our previous work. We’re proud to boast an extensive portfolio and while this used to consist of a portfolio of images, we’re now proud to boast a selection of virtual tours.
