Delivering your dream home in Wandsworth through loft conversions and extensions.

Choosing the right company to deliver your dream loft conversion or extension can be a daunting prospect. You want a team that has the expertise to build a space that delivers high quality workmanship to deadline and at the right price. Cube is the company of choice in the Wandsworth area, working with a number of clients since it was founded in 2010 to help turn their home improvement dreams into reality.

Reconfigure your existing space by converting your loft or create a whole new addition to your home with an extension - whatever your dream, Cube is on hand to make it come true.


How does it work?

Right from the outset Cube will work in partnership with you to design and build your perfect space.

The process begins with the initial no obligation, free quotation. This gives the Cube team the chance to see your home, discuss any ideas you have with you, make any recommendations from their vast experience and then marry it all up with what’s feasible - both from a design and budget perspective.

They’ll come back to you with a quote that’s completely bespoke, matching your budget, needs and ideas entirely. Once you accept the quote and instruct Cube to undertake the work, they’ll take the project management of the build entirely off your hands. All necessary legal requirements will be managed on your behalf (these include any planning permission, building control approval, Thames Water approval and Party Wall agreements where relevant).

Only once everything has been fully approved and the build T&Cs have been signed off does the build begin.

Payment is on a stage by stage basis, with the client only paying for each stage of the build if they’re completely satisfied with it.

On completion of the build, Cube offer a 3 month retention period during which the final stage of payment is withheld. Once the retention period has passed Cube will make a final visit to the property to deal with any problems that may have arisen since the build was completed. Only when the client is totally satisfied that issues have been dealt with and the build is fully signed off does the final payment take place.



Extending your home - either through making the most of your existing space with a loft or garage conversion or adding a brand new extension to it - can be a wise investment. It’s a great way to not only increase the space available for your family to use on a daily basis but can ultimately increase the overall value of your home. Whether you’re after a full design and build service or you’re already working with an architect so need a build-only service, Cube can do it all.

Converting your loft

Going up rather than out when it comes to home improvements can be the most cost effective way to create more space. With as little disruption to your family life as possible, the team will create a new living space that truly enhances the existing footprint of your home. Whether you’re looking for a new master bedroom with an en suite, a games room for the children or a workspace from which you can run your business, the Cube team will consult with you to bring together all your ideas, and offer any suggestions that could further improve your initial design.

Building an extension

Sometimes a loft conversion isn’t possible or won’t achieve the amount of new living space you’d need, so you may find you need to build an extension. Cube have worked with a number of different extension designs - from kitchen extensions to wrap around extensions, single storey to double storey - they’ve seen and built it all! They can make recommendations on design, will project manage the build, make sure all the right tradesmen on are site when needed and leave no stone unturned when it comes to a quality finish.


Overhauling your home can breathe life into it, and help you fall in love with it all over again. The way in which we use the common living areas of our homes has changed over the decades and refurbishing your home to embrace the modern open plan style of living we see today can completely open up your home and help capitalise on the existing footprint.



Hearing directly from happy customers is the best way to showcase the success of the Cube team. Delivering a 5 star service is a must - the passion and drive within every member of the Cube team is what sets them apart. Here is just one glowing testimonial from a recently completed project:

We recently engaged Cube Lofts to undertake a complete refurbishment of the ground floor of our period property in Dulwich. The layout was changed, and the major task of having underfloor heating installed carried out. We are very pleased that we used this company.
Throughout the process from scoping to contract to completion we were kept well informed and we found the company easy to deal with. The guys who did the actual work were very polite with a positive attitude . This was very important for us as we were living upstairs in the house during the 5 months project.
The quality of the work and finish is high, it was completed on budget and we have no hesitation in recommending them.
