Bricklaying- 12 Feb 2026
I hired JA Landscaping and Brickwork to build a garden retaining wall and complete patio tiling. Unfortunately, my experience with John (Jay) was very disappointing. The work was left unfinished, and the site was left in a very poor condition; even my front driveway is fully messed up with 8-10tons of waste. Despite claiming over 25–30 years of experience, the work was not properly assessed or managed, even though he was already working on a retaining wall next to the patio project at the same property and location. Although John refunded the waste removal charges £450, even that didnt covering full waste removal, the remaining unfinished and corrective work is costing me approximately 40% more than originally planned. This has made the overall project financially difficult and stressful. Based on my experience, I would not recommend this company, particularly for medium to large projects over £1k, as I do not feel they are capable of handling larger jobs professionally.

Extension Builder in Bletchley
I am a builder with 20+ years of experience, which has allowed me to specialise in pretty much every field of the sector; from tiling to fitting kitchens and bathrooms to painting etc... I am very meticulous in every job I do and always try my very best to please costumers. What I believe makes me stand out from other tradespeople is that I acquired most of my experience in Italy which is where I lived before moving here 4 years ago. This has helped me achieve different techniques and skills.

Bathroom Fitting- 7 Oct 2022
Initially did a good job but then rushed the silcon round the bath/ shower that then leaked. Kept telling us he would fix it but after more than a month I gave up and fixed it myself. Shame really, another tradesman that is fine until things go wrong!

I highly recommend Archway Building MK for their outstanding work removing our main structural wall and installing a supporting beam. Wayne delivered exactly what was promised—on time and at a fair price. His team was professional, kept me informed throughout the process, and made sure the job was done safely and to a high standard. What stood out was their reliability and easy communication. He was always responsive and easy to reach. He assisted until I got my completion certificate. I highly recommend Wayne for his services. Thank you, Wayne.

Extensions- 1 Mar 2017
From day 1 Peter has been a true professional. He was always there when he said he would to give the estimate & the quote. His quote broke down to every single item, no matter how small! this allowed me to plan & manage my finances. That was 1 of the reasons for choosing him. Throughout the job Peter was flexible & when things developed & needed to be changed, he came up with solutions before asking me. Peter & the lads (Ashley & Martin) were reliable & sometimes worked long days/Saturdays, which allowed the job to be finished a week early. The quality of the work is spot on, including mixing in the reclaim bricks & reusing bricks (to keep down costs). 4 steels needed to be put in for this job & Pete's measurements were spot on to the mm (so i've been told), plus the house never fell down while he was doing it!!! The extension has been finished & its just what we wanted. As of yet there have been no after care issues, & to be honest i'm not expecting any, so i can't give feedback on that. Would i recommend him -Definitely. The reasons- always on time, clear quote, good building skills, adaptable, came up with answers when needed, nothing to much trouble. He did what i asked for to a very good & professional standard, what better feedback could i give.

Extensions- 20 Apr 2023
We employed Phil (and Dave) to build a porch extension for us. Phil coverered all aspects of the work, from the initial chat to find out what we were after (there were no plans), to foundation digging, brick-laying, a bit of knocking through with insertion of the required lintels etc, to basic electrical and right through to plastering. All completed to a high standard and desigtned to fall within the remit of permitted development. I wouldn't hesitate to recommend Phil, and would put him top of our list of local builders if we required any further work completing, big or small. He is obviously a very experienced builder.

Conversions - General- 10 Jul 2026
Brickwork & Lintel Installation Excellence Michael delivered outstanding workmanship on the brickwork above the patio door — clean lines, solid alignment, and a finish that blends seamlessly with the existing structure. He also installed a new supporting lintel, giving the doorway the strength and stability it needed for the long term. The whole job feels very professional - both precise and reassuringly robust.

James gave us a competitive quote for our front of property new wall and arrived on the day promptly and from the word go was professional organised and obviously knows his trade. He with Byron ( my apologies if I have your name wrong ) worked very hard to complete the wall which has given our property much more kerb appeal. Excellent job James it was a pleasure having you both working at our property on our wall and I would have no hesitation in highly recommending you. Thanks again for a brill job!
