House Extension Design

  • We can offer you ideas for your house extension project, how to get the best use out of the existing building and how to extend in a way that compliments the overall building, maximises natural light, and works in a functional manner.

Home Refurbishment



  • Many older houses (and not-so-old!) have been poorly insulated and inadequately ventilated, leading to problems with damp, mould, smells, cold spots and high energy costs. We specialise in safely improving your building’s comfort and performance, eliminating mould risk, damp and making your house weather-proof.
