Clapham Loft Conversion Specialist

A loft conversion is one of the most efficient and affordable ways to add more living space to your home. It could increase your property’s value by up to 20% too, according to a recent report by the Nationwide Building Society. Whether you want to transform your loft in Clapham into an extra bedroom, a spacious bathroom, or a home office with a view, Basetop Specialist Builders can make the space of your dreams come true.

Get in touch with our team today, and we’ll help you expand your home without the time and price tag required of extensions.

A Variety of Conversion Options

We offer different loft conversions for your Clapham home. Each style has a unique benefit to your property and budget. Dormer and VELUX conversions are great if you want an affordable and fast way to add value to their property. With a hip-to-gable conversion, you get an extra room without drastically changing your roof’s appearance. A mansard conversion, on the other hand, gives you all the space you need to customise your loft.

Know Which Type is Right for You

Converting your loft in Clapham is a lot of work. As such, it’s important to know what type of space you want to have. Here’s a more in-depth look into each conversion style.

Dormer Loft

A dormer is simple, easily customizable, and affordable, which makes it a popular choice for homeowners everywhere.  It merely extends your roof to add more headspace and floor space to your loft. As such, a planning permit isn’t needed to get a dormer conversion done. The resulting room will have a horizontal ceiling and straight, vertical walls. You also have the choice to make the extension’s roof flat or pitched, depending on your home’s style.


A VELUX conversion is another straightforward and affordable way to make the most out of your space. This method attaches VELUX-brand windows to your roof while improving your loft’s interiors. No extension work is needed. As such, it’s an excellent choice for homeowners who want to utilise their loft without making significant changes to their home’s structure and look. And because this type of loft lets in a lot of natural light, it’s perfect as a home office or recreation room.

Hip-To-Gable Loft

A hip-to-gable conversion does precisely what its name suggests: it extends a portion of a hipped or sloping roof into a gable. This provides substantially more headroom and floor space than a dormer or VELUX conversion, as it takes up most of your roof’s slope. You may also get more space by utilising both of your roof’s slopes. While this method fits any home, it’s especially great for bungalows, as it essentially gives the property an additional level.

Mansard Loft

A brainchild of brilliant 17th century French architect Francois Mansart, a mansard conversion turns a whole plane or slope of a roof into a structure with a flat roof and an almost vertical wall. This provides the most floor and head space compared to all other options. Given the size of the work, a planning permit is needed to construct this type of loft. The resulting room is spacious enough to function as both a living room and bedroom. If you want extra space to turn into a rental property, a mansard loft is for you.
