had an excellent experience working with Cristian on my bathroom project. From start to finish, his work exceeded all expectations. Cristian was professional, attentive to my needs, and incredibly detail-oriented. His craftsmanship and commitment to quality were evident in every aspect of the project, and he transformed the space beautifully. He kept communication clear and made sure everything was completed on time and according to my vision. I am thrilled with the results and highly recommend his services.

Extensions- 15 Aug 2018
100% RECOMMENDED Michelle and her partner measured up and competitively quoted within a short space of time. She was then very patient and supportive when unforeseen planning issues popped up and set the start date back by quite some time. Once building started, all questions were promptly answered by either the site manager or Michelle, both being available at all times. I was away for the duration of most of the job and it was very reassuring to know that I was leaving it all in capable and honest hands. The workers were very proficient and tidied up after themselves at end of each day. They also put in some very long hours at times to hasten the work. I was also impressed by the handling of unexpected problems during the building (mainly invasive tree stumps!). I am absolutely thrilled with the end result. High quality workmanship and a beautiful building which I am sure will last many years. I would certainly recommend them without a doubt.

Bricklaying- 1 May 2026
I needed a shed done and Ranjit and the team provided a competitive quote and explained everything they would do. They arrived on time for all meetings and when the work started, worked solid every day, completing the work in good time. Shed was built to a good standard and the quality of work was very good. They tried to keep things clean and tidy and once finished left the garden clean of rubble. I would definitely recommend them to anyone looking to build a shed or similar.

What to ask a Ongar extension builder before hiring?

Before hiring an extension builder in Ongar or extension building company in Ongar, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Ongar?

An extension builder in Ongar should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Ongar extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Ongar?

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 Ongar extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.
