Fencing- 8 Nov 2026
We are extremely happy with the work carried out by Stonehaven Building and Landscapes. What started as replacing our old boundary walls and fencing turned into a much bigger project, including new fencing and gates, a block paved driveway, patios, garden levelling and new turf. Henry and his team have done a fantastic job transforming our outdoor space. From the initial visit, we felt confident choosing Stonehaven, and we're really pleased we did. The team worked hard throughout the project, and Henry was helpful and accommodating, especially as we decided to add more work along the way. The transformation is amazing, and we're absolutely delighted with the finished result. It's made such a difference to our home. A big thank you to Henry and the whole team. We would happily recommend Stonehaven to anyone considering similar work.

Extensions- 18 Feb 2016
I strongly recommend Richard (Ren Construction). The work was performed according to the agreed budget and scheduled time. Richard weekly informed me regarding each stage of the building, and its progression. Richard took control and plan a solution for any general issues related to the project, and also promptly responded after the completion of the work. On a personal level Richard is very easy to approach and to discuss the project with, and these are important qualities when you are dealing with quite a stressful time caused by the disruption of your day life; we kept living in the house during the building.

Based on my experience I have no hesitation recommending BCB Building Services who came recommended to me prior to this work by word of mouth. I needed to carry out modest renovation and remediation works on a newly purchased period property requiring many trades; general builder, scaffolder, plumber, plasterer, roofer, landscaper and damp specialist, etc. Brad and BCB team promptly provided a quote and, essential for me, agreed to source and project manage the diverse trades required to complete the work. They are busy but worth the patience and short wait necessary to get the work done by them. The workforce were professional, tidy, courteous and organised minimising disruption during the works and leaving the house clean and undamaged in their wake. The works were delivered per schedule and to a high standard and whilst not the cheapest, the pricing is fair and I believe the outcome represents tremendous value. Brad and the team remained pro-active beyond works completion and engaged actively in addressing the small amount of trivial snagging. They are now my go to for building works.

Conversions - General- 25 Apr 2023
This was work to a commercial unit. Jason and his team were absolutely excellent. Sensible pricing and started and completed the work as he'd promised. Removed all rubbish and left it clear and tidy. He organised an electrician and plumber and found a sensible solution for a damp problem that was uncovered during the works. Highly recommended...and nice people to deal with too.

Latest review:
Kevin from K7 renovations has done 2 jobs for me in the last few years, the first being an annex in my garden, the second was a full extension with high vaulted ceilings. Both jobs ran smoothly from the time I handed him my architects drawings. The things that stood out for me were Kevin's knowledge and understanding of what I required, the timekeeping of everyone on site and last but not least the site was left tidy at the end of every day. I would highly recommend K7 to anyone. I would be happy to share photos of these projects with anyone.

RMD Replaced three bathrooms, cloak, en-suite and family. The work was planned so that disruption was kept to a minimum and we were give practical advice throughout as we made the detailed decisions during fitting. The work, including cabinet making, was excellent and carried out with an eye for detail. Alex has a 'belt and braces' approach so everything was fitted to last even if it required additional work and preparation. It was all done to budget too and the pricing was fair, open and honest. RMD proved to be great quality, trustworthy, a pleasure to work with and we wouldn't hesitate to recommend them.
