We were so impressed with Beacon from beginning to end of our project. They did our loft conversion (lowering ceilings and removing chimneys), remodelled our middle floor and totally changed the layout on the ground floor. They were responsive, professional and helpful throughout the build. Sebastian was our team leader on site and was amazing - so thorough and efficient and brilliant quality of work. The project came in on time and on budget (other than optional extras we decided to add). We wouldn't hesitate to recommend Beacon.

I had an excellent experience with Beacon who were recommended by my son. They renovated a ground floor flat for me, transforming it from a hovel untouched for 50 years, into an elegant and lovely property. The project manager, Gus, could not have been more helpful, everything was well organised and moved seamlessly, and the workmanship is to a high standard. Contact with the office was also quick and efficient. Highly recommended!

Beacon provided an excellent service. Their quote was very reasonable and the loft conversion was completed in good time and to an excellent standard. Their were some issues that came up (our fault not Beacon's!) which they resolved brilliantly. The lovely Gus managed the build and was incredibly helpful and resourceful. Beacon were recommended to me by friends and I have recommended them to others in turn.

Incredibly happy with every stage of our ground floor and loft extension. The whole team were fantastic and so helpful + professional from start to finish (especially Alice and Noni). Great build quality and speed so we have already recommended Beacon to our Neighbours. Everything is still looking great 1.5 years post PC - Thanks again Beacon Team!

We would highly recommend Beacon, and have nothing but positive feedback from our recent loft conversion works (Spring-Summer 2020). Communication, administration and the standard of work completed has been excellent. Beacon also managed the lockdown situation well when this happened mid-way through our building work, and we were able to re-start safely and despite the increased complexity of supply chain issues and social distancing measures.
