Extensions- 19 Oct 2022
Great building company! Arrived each day normally by 8am, kept to schedule despite me including a new bathroom remodel and some garden landscaping! Came in on budget, with regular biweekly payments throughout the project. Very well managed, a complete solution, rear ground floor extension, new kitchen, internal decorations, create new snug and refit family bathroom. Would highly recommend and have done so already with 2 large projects currently underway.

All the trades are managed extremely well by Steve and nothing is too much trouble when requests are made.

Extensions- 29 Jul 2020
Paul at Rizer Developments was the first company to reply to my request for a builder. Paul was very quick to give us a very competitive quote and was happy to finish off the part built extension to the front of our property after a poor performance by another builder who was discharged. Rizer Developments started the kitchen extension in February as they said they would, we then had a global pandemic and shut down, not a good time to start any building project! Paul and his men somehow managed to get hold of the materials when they could. Throughout the project Paul and his men were very respectful of us still living in the house. Paul was always available if there was any questions we needed to be answered and also kept us informed throughout the build. The standard of their workmanship is a major credit to him and his workforce. We will have no problems ever asking Rizer Developments to come and do any future projects. Rizer Developments are 100% trustworthy which is so nice to see and can still exist in our modern day world. Many thanks for all you have done to make our house now a home. Peter and Carol Lewis.

Bricklaying- 29 Mar 2024
Ash repaired brickwork on the front of our 1930s semi. Replacement bricks for bay window corners couldn't be sourced like for like, so he made them himself. It all looks great. He communicates well, giving reassurance and information as needed. (He gave us useful advice about the job when other builders quoted for unnecessary additional work). Work was carried out promptly, efficiently and to a high standard.

Extensions- 17 Jul 2019
My original job of utility and porch actually grew into a bigger job, with a garden room and a completely new garden and I am absolutely thrilled with the results. Ash and his team were great, very friendly, trustworthy and respectful, nothing was too much trouble and at the end of the day things were left tidy. It was Ash that suggested we build a garden room and if we hadn’t done this we would have ended up with a rather useless corridor, instead we have a lovely building with doors that open up fully and over look our beautiful new garden. The garden was designed by Vicky Jilka and built by Ash’s team, Vicky listened to my wish list and designed a truly stunning garden. I have some more work that I would like done in the new year and will not hesitate in contacting Ash to do this. I can highly recommend Ash and his team.

Loft Conversion- 26 Jun 2019
We hired Lee at Inspire Construction for a loft conversion in Milton. It was clear within a few minutes of meeting Lee that he was right for the job. He gave sensible and reliable answers to questions from the outset through to completion and was always reassuring about any concerns no matter how big or small. He always responded promptly when contacted. Lee’s experience showed throughout, managing to take a fairly basic set of architect’s drawings and transform them in to a quality product whilst obviously still meeting all building control requirements. He used his experience making tweaks and adding attention to detail which has given a great finish to the job. He provided a schedule of the works up front and continually kept us informed of what would be happening next. The fact that our loft was completed on time, on budget, in winter and while we lived in the house must be a sign of someone that knows what they are doing. Lee is professional whilst always managing to maintain a friendly approach. He even gave our neighbour £10 to get her car washed after it got dusty one day. We were very impressed with the professionalism of all the tradespeople he worked with. They were also all courteous and considerate. It is clear he only hires people he can trust to do a top job. Overall Lee has been great value for the quality of the service we received and we 100% recommend him. In fact we already have… he has been taken on by some of our friends already.
