Bricklaying- 6 Jan 2023
Dan and his team were an absolute pleasure to work with: everyone was really friendly and polite, they kept us informed about what was happening and what would come next through the whole process, they were at work anytime the weather allowed - including Christmas Eve and New Year's Day in order to make sure the job was completed in time, and they always kept the site really tidy. The job itself was quite straightforward, but access to the site was more complicated and the team did everything they could to make sure it went smoothly and came in on budget. Will definitely be getting in touch when we need more work doing and will be recommending them to friends and colleagues.

Bricklaying- 27 Apr 2026
Absolutely disgusting, said i was a FXXKING nit picker, garage not squared, layed block to the outside of one corner and inner at the other corner, joke. Used the bricks for the final wall plate to fill gaps in wall instead of cutting blocks. Wall leaning, even admits this. To many pictures to put on here, this is just one. I only realised this after I let him go, at a cost of 300 for the day. If he replies to this I will post all of the photos for him to see.

Bricklaying- 17 Jul 2020
I posted a job on MyBuilder and received a quote from Gary @ Giraffe design & build, the quote was a fair price for the work I required and a date was set. Gary and his team arrived on time and set to work after we reconfirmed what was being done, they were left to work and made a cracking start to the job, so by the time I returned home all the prep work was done ready to start building the wall the next day, when they left, they left the site in a tidy condition, that was safe and secure. Over the next two days they preformed in a professional manor and finished a day ahead of schedule. On completion of the job I was asked if I was happy with the work carried out and the service they provided, to this I can confirm that I was happy with the work and service and would recommend them to anyone requiring their services. I've even asked to quote for other jobs I have in the pipeline. Well recommended company.

The first job Leo did for me was a new kitchen, which he helped me with the design and gave me suggestions to help it function better, all of the work carried out was to a very high standard and I was so impressed that he has also built a log store and refitted my bathroom. I was very happy hence why we got him back and will use him for any future renovations.

Byron has done an excellent job. He dealt with the demolition and the replacement with expertise and care. He removed all rubble and left the place spotlessly clean and tidy. When adjustments needed to be made he did them willingly and well. We can highly recommend By Design.

Bathroom Fitting- 20 Sep 2025
I am absolutely delighted with the refurbishment of my bathroom. From start to finish, the standard of work and the level of communication were outstanding. Piotr kept me updated at every stage, making the whole process smooth and stress-free. The transformation is incredible—thinking back to what my bathroom used to be and seeing how it looks now is almost unbelievable. The quality of the finish is exceptional, and the attention to detail really shows. It honestly feels like I’m stepping into a luxury hotel every time I walk in. I couldn’t be happier and would highly recommend this team to anyone considering a bathroom renovation.

Kitchen Fitting- 16 May 2024
Mark did a great job fitting our kitchen. He was very organised and with the timings of the job. He also did a good job of handling any issues as and when they arose (for example, altering the plans slightly to better suit the space we had). Would highly recommend if you’re looking for good quality work at a fair price.

Extensions- 1 Feb 2020
Marcus & Co were really easy to work with, dealing with issues with underground pipes and other unexpected problems professionally and efficiently. Very reasonably priced but most importantly we were able to trust him and his employees to work in out home unsupervised. If Marcus wasn’t able to complete an aspect of the job, he was able to sub-contract other tradesmen, who also worked at a high standard. We had a rear kitchen extension, utility, downstairs W/C and rendering completed in just under 3 months. I don’t think the work could have been completed any quicker. I have already recommended Marcus to friends and will continue to use him in future for other work.

What experience do you have with similar extensions in Bristol?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Bristol extension builder’s ability to deliver a result that meets your expectations.
