Recent Client Testimonials

In recent years, Alan has installed a new kitchen and added a conservatory to our 1960s property, again involving the removal of a supporting wall; refurbished a family bathroom to maximize the available space and created a downstairs shower room. Due to his professional approach, Alan enjoys a good relationship with Local Authority Building Control officers and ensures all his work is compliant with current Building Regulations. We have recommended Alan to several of our friends and would not hesitate to do so in the future.
Over the past 15 years Alan has carried out a number of building projects for us on two different properties.
On our terraced period property, he completed a loft conversion and the removal of a supporting wall and chimney breast to create a large kitchen/dining area. Both these projects involved co-operation with the adjacent properties which shared a party wall. Alan’s attention to detail meant that all the new woodwork and staircases were in sympathy with the original building.

The most important thing was obviously the quality of the build and the interior and exterior finishes. Alan and his men had all this covered and we were very impressed with what we had seen so much so that we appointed him as our builder on the extensive enlargement and refurbishment of our house. Alan and his men completed the work on our house in a timely fashion.

We first met Alan and his men when we went to look at a new build house he had almost completed. We were very impressed with the quality and finish of his workmanship and that of his employees. Also we hadn’t realised that his contract with his then customer, extended to helping unload the shopping and removal boxes.

Alan and his men had all this covered and we were very impressed with what we had seen so much so that we appointed him as our builder on the extensive enlargement and refurbishment of our house. Alan and his men completed the work on our house in a timely fashion. He project managed the build so that there was a constant flow of activity and called on other specialist professionals from his broad spectrum of connections. He incorporated managing the site and sourcing materials whilst being hands on and on site everyday, working side by side with his men. He made us aware of things we might not have thought of and we incorporated many of his ideas. Nothing was ever too much or inconvenient for him and his men, even when we changed our minds, our happiness was paramount. Very reliable and easy to get on with and they kept the site clean and tidy so much so that we never experienced the layers of dust, many people refer to, that  normally keep settling weeks after their project is completed. A very personable man with a lovely team behind him.

Mr. & Mrs. G. Erol

I would have absolutely no hesitation in recommending Alan – in fact, I already did, to my best friend! I was delighted with the both the quality of the work and the manner in which it was undertaken. Alan and his colleagues were a pleasure to deal with, and Alan was always honest about the progress of the work, any issues arising and the costs. He’s so good that I don’t really want to write this as it might mean that he’s too busy next time I have a building project!

Mrs. C. Walden

The building operations were carried out in an efficient manner, with Alan controlling his workforce and material suppliers from start to finish in a very professional manner. I particularly liked his attention to detail with the construction, and would not hesitate to use him for future work, or in recommending his company to others.
Last year I required a building job to be carried out at my residence. Alan’s company was recommended to me, so I asked him and two other builders to supply an estimate for the works.
The quotation received from Alan was competitive and I sent his company the order.
Alan visited my house and together we formulated a programme for the works.

Alan and his team completed a loft conversion for us last year. From the moment we met to discuss our requirements through to completion, Alan has been professional, reliable and a complete perfectionist. He and every member of his team take such pride in their work and the attention to detail shown by every single one of them is amazing. Our standards are very exacting (which Alan himself will attest to) but they even exceeded our expectations and were always thinking ahead, considering things that would never have crossed our minds.

Our standards are very exacting (which Alan himself will attest to) but they even exceeded our expectations and were always thinking ahead, considering things that would never have crossed our minds. Not only is their work of the highest quality, the team are all incredibly neat and tidy. We can honestly say that we didn’t encounter any of the residual building dust that is so often referred to.  We have two small children and not only did they make sure the house was kept clean and free of any danger at all times, Alan and all of his team were wonderful with them. Our daughters were very upset when I told them the building work had finished and that they would have to say goodbye to them all! Even our neighbours commented on how polite and professional the team were throughout the build.
Alan was always accommodating and patient(!) with us, even when we slowly but surely expanded the remit (the price you pay for being so good!). The job was completed on time and to budget and we couldn’t be more thrilled with the result.  We couldn’t imagine using anyone else and would highly recommend Alan and his team to anyone (and we have to everyone who has visited us, seen our lovely loft, and invariably asked for his number) but not before they come back to start on our other rooms!

Our Process

    Initial Consultation

    We begin by listening. In your initial consultation, we take time to understand your goals, budget, and vision for the project. Whether you have detailed plans or just an idea, this stage sets the foundation for everything that follows.

    Design Concept

    Our team develops a design concept tailored to your needs. We consider layout, functionality, and aesthetics — presenting you with a clear vision for your project. We’ll collaborate with you to refine every detail until the concept feels just right.

    Building Regulations Package

    Once the design is approved, we prepare a comprehensive package for building regulations approval. This includes detailed technical drawings and specifications, ensuring the project meets all required standards and passes smoothly through local authority checks.

    Quotation

    With the approved design and specification in hand, we provide a detailed, transparent quotation. This gives you a clear breakdown of costs, timelines, and scope — no hidden surprises, just a professional proposal you can trust.

    Construction & Sign-off

    From groundworks to final finishes, we handle every stage of the build. Our team manages the entire construction process with precision, keeping you updated and the site running smoothly. Quality, safety, and efficiency guide everything we do.

    When the work is complete, we walk you through the finished project to ensure every detail meets your expectations. Once you’re fully satisfied, we formally sign off — and leave you with a space that’s ready to enjoy.
