EXCELLENT Based on 10 reviews Posted on JC Building Design LtdTrustindex verifies that the original source of the review is Google. We have worked along side Josh & Ash from the initial design enquiry to build completion. Josh is very proactive and reactive to all customer questions from the initial enquiry, ensuring the client is updated on every stage of the design even before the build commences. During the build correspondence is a must for clients, and Josh is 100% there for every question and minor details the client asks, reassuring for the client who is having their dream built. The quality and detail of their work is excellent, a "builder" who can actually read drawings and comfortably communicate with other professionals involved behind the scenes. It is a pleasure to work with Off Market Developments, and I have no hesitation in working along side them or recommending them to my customers.Posted on Dom WilmoreTrustindex verifies that the original source of the review is Google. We used Off-Market Developments for a wraparound double-storey extension. As most people know there is always apprehension and anxiety with building work which is why I chose Off-Market due to the recommendations I had in person. Ashley and his team were professional and kept communication clear from start to finish. The most important part of the job the workmanship was immaculate. Every target set was hit on time with great attention to detail in every aspect of the build, the lads were a pleasure to have at my property and I cannot fault them at all, I will happily recommend them to anyone for a job thankyou for such a great experiencePosted on Kelly PhillipsTrustindex verifies that the original source of the review is Google. We recently had a single-storey house extension completed, and I couldn’t be happier with the entire experience. From the initial consultation through to the final finish, everything was handled with professionalism, attention to detail, and clear communication. The team really took the time to understand what we wanted and offered helpful suggestions to make the most of the space. The build quality is outstanding — the new extension blends seamlessly with the existing house .It’s brighter, more spacious, and far more functional. The project was completed on time and within budget, which made the whole process stress-free. The builders were punctual, tidy, and respectful throughout, always keeping disruption to a minimum. I would highly recommend this service to anyone considering a home extension. It’s added real value to our property and genuinely improved our quality of life. A five-star experience from start to finish!Posted on Tina McguireTrustindex verifies that the original source of the review is Google. Ashley, Josh and Billy have been absolutely brilliant, they have done a fantastic job of our extension and garden! Highly recommendedPosted on Sheryl SmedleyTrustindex verifies that the original source of the review is Google. Absolutely outstanding workmanship. From the first meeting to the end result, these guys were so professional and polite. Very clean and tidy. Would highly recommend and would definitely use again. Good job guys and thank you very muchPosted on Simon Rourke (the_sawdust_room)Trustindex verifies that the original source of the review is Google. Ash was very professional and hard working. He came to have a look and assess what was needed. He then gave me a quote and a date and time of when the job could be done. He arranged for all of the stock to be delivered before the job start date. He turned up early in the morning, and didn't stop until the job was completed. 100% happy with the work ethic, price and quality of work. Will definitely use again.Posted on Mike RobinsonTrustindex verifies that the original source of the review is Google. I was recommended Ashleys services by another builder quoting “the best brickie he knows.” I used Ashleys services to build my dream pond. He was on time and his communication was great. He non stoped grafted and blew all my expectations out of the water with how fast it went up. Great skills, great price! Will recommend and use again.Posted on Victoria MasonTrustindex verifies that the original source of the review is Google. Excellent service all round. Brilliant experienced team that really go the extra mile. Highly recommended, you can be confident all work will be carried out correctly and efficiently. Thank you to Ash and teamPosted on olivia muncasterTrustindex verifies that the original source of the review is Google. Ash and his team are brilliant, they did a fabulous job of our extension, glad to see he has finally gone for himself full time! Thank you and all the best 🩷Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
