Plastering- 29 Aug 2025
I asked Daniel to check and price some pebble dashing job. Daniel was fair in his pricing. He was on time in commencing the work as we had agreed. He never left the site until the job was completed within a few days, hence causing least interruptions. I do recommend him and I intend to ask him to carry out works in future.
HEXAFORM CONSTRUCTION LIMITED
Rating: 5 out of 5
Extension Builder in Erith, Greater London
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.

Akash made sure the job was complete exactly how he said it would be, he provided reliability during the installation of our kitchen and answered all questions very professionally. The builders were well aware of the conversations my mother and I had with Akash and so put our mind at ease. The installation itself was very quick (the tear down was very much completed in a few hours) and installed over the weekend. They were very hygiene aware and set up a cover between the kitchen and the rest of our house and didn’t disrupt our home living. They cleaned up before they were gone to very high standards without us even asking them too, all I’m sure is due to Akash’s excellent organisation skills.
