On top of our excellent craftsmanship, we pride ourselves on providing you with complete convenience and ease throughout the entire process and we do this by offering a fully inclusive service. From the initial design stage, through to planning and subsequent construction, we take on every aspect of the process ourselves.

We ensure complete transparency and do our best to make the process as smooth as possible.

We understand that every loft conversion will be messy at some stage but we’ll do our utmost to ensure you can continue to enjoy your home space for as long as possible throughout. 


In the heart of Balham, Clapham Construction brings a fresh perspective to loft conversions. We recognise that Balham, steeped in history and bustling with modern charm, isn’t just a place—it’s a lifestyle. Our design ethos mirrors this, capturing the elegance of landmarks like the Victorian-era Balham Station or the Art Deco Du Cane Court, and integrating it into our loft conversions. We aim to create spaces that respect history, relish the present, and look towards the future, much like Balham itself. As your neighbours, we strive to ensure your loft conversion complements both your needs and Balham’s unique character.

Loft conversions in London are one of the most popular methods of home renovation for the simple fact that they require no extra floor space and they make use of what is essentially dead space you already have in your home. 

Add to this the fact that they can add on a fantastic amount of value to your home and it’s clear to see why so many choose to extend their home with the help of a loft conversion.

From additional bedrooms with ensuites to games rooms and more, a loft conversion can be put to so much use and what’s more there are so many different ways to do them too.

With the help of our incredible team here at Clapham Construction, we can help you achieve the loft conversion of your dreams.
