Cube Lofts did an excellent job for us and we would highly recommend them if considering home redevelopment and/or extension in SW London / Surrey. We rate them 4.5 out of 5 with the only negative being lengthy delays in completing snagging works but otherwise the quality of delivery was top drawer.
The project was delivered broadly on time despite Covid, with the original scope coming in on budget (unexpected costs the job progressed). We have subsequently recommended CUBE to two separate friends who appointed them and had similar positive experiences.
Working with a small but professional business like Cube meant dealing with skilled and genuine people who care about quality and were aligned to the project's success, working with us through inevitable build issues, but offering solutions rather than simply problems.
Below is a more detailed summary for those interested:
Our project comprised a new dormer loft and outrigger, first floor & ground floor remodelling, with a rear wrap-around side extension. We tendered the work as two packages to multiple contractors. Cube were ultimately appointed to undertake design, build and project management services, our rationale being as follows:
- Competitive on price for both packages / Proven local track record
- Directly contract with build crew (rather than subcontracted)
- Continuity from scope and design, through to mobilisation, build and exit.
- Incentivised contract with c40 stage payments aligned to scope and payable once each completed. Further retainer upon PC for 3 months in case of defects.
- Members of Federation of Master Builders
- Insurance backed guarantee
- Willing to demonstrate not over stretched in terms of live projects
- Not a reincarnation of a previous business that have been in administration, unlike competitors.
CUBE patiently worked through our design brief through to planning submissions. Tristan (sales & design lead) clearly articulated the scope of works and impact of certain decisions. We received regular updates throughout and secured planning with no conditions. Tristan then handed over to Sally (PM) and Piotr (Master Builder) with Mariusz (owner) providing oversight.
Works started March 2020 before the first lockdown. CUBE were prepared and continued uninterrupted. Sally, Piotr and his team were superb during this period, with an exceptional work ethic (6 days a week and full days 8am-6pm), being polite and patient, courteous to neighbours and tidying up. They were highly proactive, regularly forward purchasing materials as supply shortages kicked in.
Various unexpected costs materialised during the build including insufficient power supply, defective roof tiles, drains and joists. Sally/Piotr came up with credible cost effective solutions and were fair/ transparent with on costs breakdowns rather than generic bills with hidden margins.
As we were expecting our first child in late October, it was essential we stuck to programme. Sally kept a firm hand of the project with weekly detailed progress briefings. Ultimately, we lost a few weeks due to material supply delays (kitchens, white goods etc) and although some subcontractors were unreliable, Piotr kept his team focused and came up with workarounds to recoup lost time without compromising on quality.
Main works PC'd as our daughter arrived in early November. This left the snagging list and although CUBE left us in peace for a couple of weeks, the team moved onto different projects and it proved challenging to get them to return, taking several months to clear the list off. In hindsight had a full crew been made available for 2/3 days then most would have been resolved. Cube acknowledged the snagging works went on unnecessarily long.
Overall, however, we would definitely use CUBE again and continue to refer them to others. A big thankyou to Mariusz, Sally & Tristan and likewise Piotr, Andrew, Josef and all the build team. We are delighted with our new home and should we decide to do another project we will be in touch!

Even at the quote stage, Cube stood out for us by considering the individual nature of a project rather than a ‘one size fits all’ approach. The level of thought and diligence in the planning and execution demonstrated their wealth of expertise and diligence. Communication and project management were excellent throughout. We recommend them wholeheartedly and are using them again on a second project.

Cube did a great job managing and building the refurbishment of our house and ground and first floor extension. They had a great work ethic and nothing was too much trouble for them. We are very pleased with the final result and I’d be happy to recommend them for similar projects.

The renovation of a complete house is a daunting prospect but Cube Lofts gave us confidence and reassurance from the start. They came up with clever ideas for the new layout and design of the house suggesting things we would never have thought of.

Obviously the budget was an issue and Cube Lofts kept within this and even suggested some savings. The project was completed on time and the team worked extremely hard to make this happen and were always polite and considerate. The project manager was always contactable and regularly visited the site and dealt with any issues that arose immediately.

We would be more than happy to recommend Cube to prospective clients.

We are very happy to recommend Cube. They were friendly, courteous extremely efficient and completed a fantastic extension to our house which we are thoroughly enjoying using. The work they did was carried out to a high standard and was completed on time!

We would like to say that Cube Lofts have done an excellent job in making our house a beautiful place to live, we are so pleased with our new kitchen and bedroom, they are stunning. The whole project ran smoothly and we were delighted with the building team who always worked hard and were on the job first thing in the morning to late in the day. The project manager was always available and we were impressed with the quality of workmanship. Cube tried to keep disruption to a minimum and kept the site clean and tidy.

We would have no problem in recommending Cube to anyone thinking of having work done to their house.
Very good experience with thoroughly professional team. The whole experience was a positive one - I would highly recommend them.
Great firm - will be flexible and helpful in achieving your dream conversion. I would strongly recommend them.
Many thanks again - we look forward to also gradually sorting out with you all the other decidedly dodgy plumbing in the house. The previous builder’s plumber was a nightmare and you have no idea how great it now feels to have found someone we trust!
