Extensions- 23 Feb 2020
We hired Arra brickwork to complete what looked like a straight forward side extension, this soon became very complex due to the angle of the build and the roofing. Whilst we had our own expectations, Aushra was very helpful in presenting more ideas and suggestions in line with what we wanted. She even went as far as building sample model to show us what the build would look like. We found Arra brickwork - Aushra and Authur to be genuinely nice people, they are very polite and very tidy workers and put in so much effort to complete the build, even when we didnt expect them they were there working hard. We had full visibility of spend as Aushra was prompt at letting us know how much materials would cost including the initial quote for the build which was reasonably compared to what we had previously been quoted. We could not ask for a more trustworthy team of builders who cares about what they do and I will not hesitate to hire Arra Brickwork again for any more projects.

Loft Conversion- 20 Jan 2026
I have chosen Byron and his company to complete my loft conversion. Job was completed within given time frame. Byron and the team were polite and hard working. During the building time, any issues found by myself were addressed and rectified as much as possible. At the closing weeks of my project, I have asked Byron to complete additional carpentry tasks. He found the time to accommodate my requests. Job had some messy stages but Byron was always trying to leave site clean as much as it was reasonably possible. Thank you for your work and I would be happy to hire you again in the future.

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.

Do you offer a guarantee for your work? Most Ongar extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
