Really impressed with Cube from start to finish. Project management for our loft conversion by Sally was excellent, and Michal was the most professional and thorough builder we’ve ever experienced. They took care of everything from plans and planning permission right through to final finishes and handover. Nothing was too much and they were super flexible - I wouldn’t hesitate to reccomend and would use them again in a heartbeat.

CUBE assisted us with a two-storey-side and loft extension, all the way from the design to the final product and we could not have been happier. As a first time “builder” we benefited from their wealth of experience, were guided through the million of decisions, advised on timelines all throughout the project and kept up to speed with any developments of the built. Our builders were fantastic, not only did they do a fabulous job, they also finished the entire build in 7 months while we were still living in the house. They worked around us at all stages and displayed patience and problem solving thinking with any challenge that came up. We really could not have had a better experience and I have recommend Cube and our builders on several occasions already. We love the look of our extension, the clever ways that space was maximised and the overall finish. Our house in fact looks like it was never extended… which is more than we could hope for.

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!

Following a recommendation from someone-else on our street who had used Cube a few years earlier, Cube’s quote was the only one we got for our loft conversion in 2022. And now, well over a year since the main work was completed, we are absolutely delighted with the end result and can whole-heartedly recommend Cube to others. A key reason we chose Cube is that their builders, plumbers, electricians and decorators are contracted exclusively with them. Consequently, by the end of the project design phase, Cube are able to provide detailed schedules for the build work and for the payments as each stage is completed. Therefore, from the outset of the build phase, we knew what we’d be paying at each step, and when. Our project, to convert the loft space into a large bedroom with eves storage and a separate shower room, involved replacing the entire first floor ceiling. This necessitated that we move everything from the first floor down to the ground floor or into storage, and live elsewhere (close by) for three months. Remarkably, we were able to move back in on the intended day, and the rest of the work was then completed with minimal disruption for us. But it’s not that everything went exactly to plan! For example, the shared chimney stack turned out to be frighteningly unsupported on our side, tight space on a party wall required a change in construction of the junction, and there was a significant leak of mains water from an existing toilet. However, every time there was an unforeseen problem, our expert builder, Sebastian, came up with a solution. And anything that went wrong was swiftly put right. The final stage of the project was very protracted, mostly due to supplier delays outside Cube’s control. But ultimately, the snagging and every last little thing was finished to a very high standard. Our great thanks go to Sebastian, and to our fantastic Project Manager, Ann, for their expertise and professionalism and, not least, for their truly impressive negotiation skills in dealing with an awkward neighbour. 10 out of 10 for our Cube experience!

We used Cube for a loft conversion and general remodel within our house. They were very efficient and professional from quoting, scoping and inception meetings, right the way until the end of the project and getting Building Control sign off. Michał and his team of builders were exceptional, with Sally overseeing and managing the scope. It went surprisingly smoothly for a project of this size and this was down to the excellent communication and management from Sally and Michał’s responsiveness to problem solving and his generally high standards of work and the pride he takes in it. We are very pleased with the result and would recommend.
