Extension Builder in Waltham Abbey
We specialise in all types of brickwork and undertake projects of all sizes, with a strong focus on quality rather than quantity. Much of our work is delivered on major construction projects, and we also have a dedicated team available for private residential work, including weekends. We specialise in substructure waterproofing, which is essential for any new extension. Spending a few hundred pounds on proper waterproofing now can prevent costly damp and water damage in the future. We also have experience in Passivhaus construction and Passive Purple airtightness systems, helping clients achieve improved U-values, better energy efficiency and reduced condensation.

We are extremely happy we chose to use Phil for our loft and extension design. Phil is professional, extremely accommodating and a pleasure to work with. He was always contactable, punctual and happy to spend a lot of time with us to discuss designs and the planning process. His design ideas were smart and he presented us with a number of workable options. We wouldn’t hesitate recommend Phil and would certainly use again for any architectural works.
