We recently had our 3-bedroom house renovated, along with a new rear extension build and a garage conversion, and I couldn't be happier with the results. The team demonstrated exceptional craftsmanship and attention to detail throughout the project. From the initial consultation to the final handover, they were professional, reliable, and transparent about costs and timelines. The renovation completely transformed our home, enhancing both its functionality and aesthetics. The rear extension seamlessly integrates with the existing structure, creating a spacious and light-filled living area, while the garage conversion provides a versatile space we can now use as an office. The team was approachable, accommodating any changes we requested during the build, and always left the site clean and organized at the end of each day. I was particularly impressed with their ability to stay on schedule despite some challenging weather conditions. If you're looking for a dependable team that delivers quality work, I highly recommend Blueprint.

Alex and his team did an amazing job. We hired them for a simple garden renovation project, but then as the job was going ahead and as they were extremely knowledgable, we decided to redesign the whole garden. They made the foundation for the rear extension, they disposed the old shed and decking, laid the new patio at the end of the garden and built a garden house with a toilet and kitchen. They also laid the rear patio (attached to the property) and built a covered outdoor area with a bbq and wood fired oven. It was a very big project and we are very happy with the outcome. Such an amazing transformation and we couldn’t have been more lucky in choosing A.V Structures. Very highly recommended.

I Hired Em to do my ground floor reno, which included a garage conversion and remodel of my kitchen where 2 internal walls were removed. Very glad I found Em to do the job. Him and his team was efficient, friendly, tidy and hard working. We encountered obstacles along the process (which is normal for any renovation) but Em gave his opinion, listened and we came to the best solutions. Very happy with the result. Em is a reliable, punctual, knowledgeable, fair, down to earth guy and one of the best if not the best contractor I have hired. Highly recommend. Some before and after pictures.

Bathroom Fitting- 25 Nov 2020
Alex provided a great service. He came round on time to view the job, gave a detailed and competitive quote and built the bathroom exactly to spec. He was keen to ensure I was happy with all aspects of the installation with regard to both materials and workmanship and even carried out some small additional activities not included in the original quote. He was polite, hard working and very experienced. He also cleaned up the house at the end of each day. I am really pleased with my bathroom and would thoroughly recommend him to anyone.
