Conversions - General- 3 Apr 2026
Where do I start. I’ve had more communication with Stuart in the last few months than I have had with anyone else. Our house has rare coloured bricks and I was absolutely shocked that Stuart managed to match the bricks perfectly. Stuart completed the work to such a high standard, we have arranged for him to come back to complete the inside of the extension also. Stuart quoted a really good price, turning up on time everyday. Honestly couldn’t recommend him enough and we will be using Stuart for all future work we intend to have done.

Latest review:
We initially hired Michael to convert a bathroom into an office. After meeting him and discussing our longer-term plans, we quickly felt confident moving forward with him on much wider renovation works across the property. Michael worked closely with us throughout the entire process—from early ideas and structural planning through to execution. He consistently provided insightful, practical advice that added real value. His ability to anticipate issues early not only prevented problems but also helped us save money by refining the plans to maximise our goals and avoid unnecessary costs. Michael’s broad knowledge and skill set were hugely beneficial on a project of this size and within a tight budget. He made the process far less stressful and, at times, genuinely enjoyable. He kept me informed and involved at every stage, which gave me a great deal of confidence in both the quality of the work and the decisions being made throughout. Michael helped us renovate every corner of our four-bedroom maisonette in West London—from bathrooms and structural opening-up works to a full kitchen renovation, hard landscaping, flooring, and carpentry. The list goes on. His wide skill set and depth of knowledge were truly impressive and exactly what we needed, particularly as we chose to stay closely involved in the renovation rather than hiring a larger construction and project management company. We genuinely don’t feel we could have made a better choice. It’s not always easy to find a builder who is reliable, honest, and trustworthy, so I feel very fortunate to have worked with Michael. I would recommend him without hesitation and will absolutely continue to work with him on future projects, big or small.

Conservatories- 14 Jun 2026
Wow, Xavia and his crew have done an amazing job replacing old polycarbonate conservatory roof with a solid tiled, insulated warm roof. I couldn't recommend these people enough, clean, curious, and experts in my opinion at all that they do. They went over and above when the weather changed to unforeseen heavy rain, and made sure we were watertight throughout. Lovely people, wonderful job, the best tradesmen I've met on my 64 years on this planet. Thank you.

Gas Work- 7 May 2019
Jason was a breath of fresh air. He is highly professional, totally ethical and has great integrity. Unlike many engineers who took no time in quoting me for a brand new boiler,Jason checked the boiler to accurately ascertain what precisely was wrong with it in order to determine whether a new boiler was necessary at all. He identified the problem to an external loose valve above the boiler which was leaking. He kindly tightened the valve and stopped the leak. My sincere thanks to Jason for saving me in excess of £3000.00!

Restoration & Refurbishment- 26 Jun 2022
Tommy was a wonderful perfectionist and has done beautiful work in our stairway and hallway which had needed refurbishment for a very long time. It feels brand new. The flooring is perfect both in the hall and staircase, and the walls are now perfectly smooth and painted immaculately. Friendly and accommodating, we will be hiring again for more jobs in the future, undoubtedly. Thank you.

HEXAFORM CONSTRUCTION LIMITED
Rating: 5 out of 5
Extension Builder in Whetstone
HEXAFORM is a London based multi-disciplinary design and build company that has the experience, work ethic, communication tools, and systems in place needed to bring any scale project from a virtual blueprint to reality. Historically the architect-contractor relationship has been one of an ‘us versus them’ mentality. But we’re 'both'. Having a design team under the same roof as a construction company means that the eccentricities of each project are rendered opportunities, rather than obstacles.

Extensions- 17 Jul 2020
Orgert Myrta and his highly skilled team did an exceptional job renovating our Victorian terrace house in under 8 weeks. On meeting Orgert, his warm, friendly and professional manner was reassuring. I immediately thought he was someone I could work with. His initial assessment of our house, he advised on best possible solutions to achieve our aims within budget. He invited me to visit the homes of his recent previous clients & obtain their feedback, which I did. Visiting two clients, they both spoke highly of Orgert & his team, sharing their positive experience and how Orgert has since completed work on their neighbours homes & family members homes too. Judging by the quality of work completed in both client's properties, I knew Orgert was the right builder for me. Responsive & prompt throughout, good communication, providing weekly status updates, even advising on where to source great deals on second fitting items saving us money. To say we are pleased with how well the project has gone & level of workmanship is an understatement! Without hesitation we highly recommend Orgert & his team, who since finishing our house are now doing work on my relatives house. Orgert & his team completed in our home: - Rewiring & new plumbing - Plastering walls & ceiling - Replace old ceilings - Painting & Decorating - Painted exterior front & back - Replaced & repointed brickwork - Installed new kitchen & bathroom - New flooring throughout
