Double storey wraparound extension
We couldn’t be happier with the work carried out on our home. Focus Builders completed a two-storey wraparound extension including two new bathrooms and a large open-plan kitchen, and the entire experience was excellent. From the outset, they reviewed our plans, discussed our vision, and offered valuable advice, which built trust immediately. Communication was clear, honest, and consistent throughout. Any questions or changes were handled professionally and with ease, giving us confidence at every stage. The quality of workmanship is exceptional. The extension blends seamlessly with the existing property, and the attention to detail, particularly in the bathrooms and kitchen, is outstanding. The team were reliable, respectful, and kept everything tidy. The project was completed on time and within budget. THANK YOU :) Focus Builders.
