He started the job but went away without finishing it just because he couldn't fix the hinges, which wasn't a rocket science. I would never hire him again.

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.

Very happy with the extension. Eddie and his team were best priced which was the reason we went with them, and he brought in a crack team of brickies, roofers and notable mention to the tilers.

Extensions- 29 Jan 2015
PM Building epitomise what a modern day, professional building firm should aspire to be. Transparent pricing, a friendly team working 6, sometimes 7 days a week to get the job done quickly, an eye for detail and very high standard of final finish. All comms and the overall work is run through Bart, who answers to phone, text or email quickly and frequently outside normal working hours. This is ideal if you work during the day and cannot be around to oversee things directly. We also got PM Building to make us a bespoke kitchen, again very high quality and millimetre perfect. If I had to find some negatives, they are not the cheapest company you could find, but there again you get what you pay for; also, we developed a few issues with some retaining walls in the garden, however, they returned when I contacted them long after the work had finished and fixed them! All in all, an excellent, honest and professional company to deal with. I would, and have, recommended them to friends...nuff said.
