Why CS Lofts
Most loft conversion companies in London sub-contract work to smaller companies. At CS Lofts we take full responsibility for your project, with a dedicated project manager overseeing every stage to completion. We only employ the best craftsmen, by choosing CS Lofts you can potentially save thousands while receiving a higher quality of care and service on your loft conversion.
Once we issue your quote the price is fixed, we sign a contract upfront guaranteeing the cost of the job and this will only change if you request additional work or in the unfortunate event that a pre-existing issue needs resolving. We pride ourselves on transparency and this shows through every step of our process.
We keep you informed throughout the project, ensuring we understand your requirements so that we always exceed your expectations.

Design and build
CS Lofts recently built my loft conversion. Richard and Sam managed the project exceptionally well. I could not have asked for a smoother experience. The company is professional but also very approachable and took all my considerations into account. All workers were polite and very experienced. They also finished in record time to the highest of standards. I would, without hesitation, highly recommend CS Lofts to anyone thinking of converting their loft.

CS Lofts’ quote was all inclusive and very comprehensive”, “I found the builders really friendly and they just got on with their work really quickly”, “The team were really friendly, easy to get on with, there were no additional extras and nothing was too much trouble

Design and build
Design and build contracts are used where the design and construction are contracted to a single entity, allowing the overlap of these phases and shortening the overall project delivery time. By using our own architect and structural engineer, everything is taken care of in house so you can sit back and let us take care of everything.
All our quotes include architectural drawings and structural calculations as standard. By doing everything in house we can reduce costs and pass on these savings to you in one fixed price. In addition, our architect and structural engineer specialise in the design of loft conversions which helps avoid delays from designs that might work on paper but don’t factor in the unique details of your loft.
Fully insured
unique penalty clause
no subcontractors
Unique penalty clause
Every contract issued by CS Lofts specifies the length of time the build will take in weeks, if the build exceeds this time we will deduct £500 per week from the price of the work.
This is a promise that we will complete the build in the agreed time. This protects you from companies that start work but then leave scaffolding up for a year before they complete.
Many companies say you are protected by stage payments but once they have secured the work they no longer have an incentive to complete as they know they can finish and get the final payment when it suits them.

No need to move
Moving home comes with a significant number of costs including stamp duty, agents’ fees, surveyors, and removal fees, not to mention a considerable amount of time and stress!
If you are looking for more space for a growing family, visiting relatives or to work from home a loft conversion can meet all of your needs and more. A loft conversion typically adds 50 cubic meters to your home, enough space for two bedrooms and an ensuite, or perhaps that grand master suite you have been dreaming of?
Whether you are looking to create your forever home or add value before a sale a loft conversion makes great financial sense, adding as much as 20% to the value of your property.
Why go through the upheaval of moving children’s schools and leaving your local community when the extra space you need is there waiting to be converted by CS Lofts. Before deciding to move home, make sure you check out the types of loft conversions offered by CS Lofts including Hip to Gable Conversions, Velux Roof Conversions and Mansard Conversion to name just a few.
