Cherrywood Design & Build Ltd
No reviews yet
Extension Builder in Merton
Cherrywood was born from a deep passion for building things that last not just in form, but in feeling. From the earliest days, our work has never been about simply putting up walls or laying down foundations. It has always been about creating spaces that breathe, carry meaning, and quietly stand the test of time. What began as a small practice rooted in hands-on work and honest craftsmanship has gradually evolved into a collective of designers, builders, and visionaries, each bringing their own touch of precision, creativity, and care. Together, we believe that the details matter. That every corner holds intention, every line speaks of thought, and every finish carries a sense of pride.

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

Worked with Phil within a number of public sector projects all of which had to be delivered in a highly pressurized time frame with a focus on quality and sustainability. Would recommend Phil as a skillful tradesman who can work positively with his clients in a professional way whist retaining the highest integrity and drive to achieve best value and product for his customers. v. I have worked with Phil on projects valued between £2000 and £400,000 and have found his skill set, person-ability and communication skills to be of enormous value.

HEXAFORM CONSTRUCTION LIMITED
Rating: 5 out of 5
Extension Builder in Merton
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.
