Extensions- 1 Feb 2023
We are in the last week or so of the extensive remodelling of the kitchen, utility room beyond plus bedroom upstairs. Mark Lomas and his team have been truly amazing, not just in exercising real building skills to blend the extension harmoniously with the existing Edwardian home but also in some imaginative problem solving as well. Costs have been spot on budget, save where I have caused additional work and fitting out, other than some unusual costs arising from some specialist joinery work which enabled the timber windows and doors to be exact replicas for others built 120 years ago. Honestly, I could not speak higher of the care and attention we have been given. I could get cross about the driving rain and the gruesome frosts and miserable cold, but that's a British Winter for you; Mark and his team certainly did not grizzle, and have stayed professional throughout. Circa £100k budget, so a reasonably size job and quite a risk for the builder - for my next project, I shall certainly use again in a heartbeat.
