Extensions- 19 Feb 2020
TCB took on a large extension / remodelling for me, starting in autumn and going through the winter. Despite the bad time of year, the project was completed on time, in budget and with a high-quality finish (plenty of neighbours have commented on the quality, speed and friendliness of the team). Trustworthy, very accommodating when things didn’t go to plan and kept me updated with progress while I was working away. Would want to use again and can highly recommend.

Architecture- 5 May 2018
Contracted to provide options for a new garage office and storage solution. They turned up promptly and were very polite and professional. Through many discussions they ultimately offered up a very good bespoke solution for our situation and once planning is approved we will have no issue with looking to them to complete the actual build. We have had a lot of issues in the past finding reliable trades but with ArhiTERRA design and build we felt confident in their ability to both visualise and implement the build as well as follow through on their promises. I would say that for anyone considering discussing a project with them that it is worth your time to at least have a meeting with them and judge for yourself.

Latest review:
This was a whole house refurbishment involving a garage conversion to an office and a utility room and a doorway through to the main room. The whole of the downstairs was opened up removing walls and replacing with steel girders. This required further footings to be installed and vertical and cross beams to support the structure. Also removed a door and windows to install bi-folding doors. All then plastered and made good. Cavell employs a team of very friendly, happy and accommodating tradesmen and his overall aim is to make sure the customer is happy with the end result. He was also very accommodating and helpful when problems arose. I have since employed Cavell to do a whole refurbishment of a rental flat and several other minor works and repairs. We are now embarking on another whole house refurbishment which will involve a two storey extension and walls to be removed and steels installed. I would have no hesitation in recommending Orange Tree Construction.

What to ask a Ongar extension builder before hiring?

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.
