Bricklaying- 28 Feb 2021
Brilliant job by Craig - he had to correct poor work done by my previous builder, and i wish i had hired Craig straightaway........ work was done to a superb standard, and all finished very neatly, and measured properly so windows and doors fitted as they should. All mess was cleared up and left tidy, and they even left my mixer cleaner than when they arrived. Would certainly recommend, and will get them back if i need anymore brickwork, groundwork, patio, drive etc doing. Keep up the good work!!

Kitchen Fitting- 26 May 2021
Obtained a few quotes for two jobs - install new kitchen and new bathroom. Steve was not the cheapest but it’s not all about price. He was the most thorough whilst quoting and had a genuine interest in the job and made some extremely useful suggestions. The work is now in progress and I am so pleased we went with Steve. Really couldn’t ask for more - constant updates and work being carried out efficiently. I have several properties that are rented out and in future I look forward to working with Steve. Thank you.

Extensions- 26 May 2025
Thomas and his team were excellent to work with, through from the planning stages to completion. We had a garage extension built and Tom was able to perfectly match the existing bricks. The work schedule was stuck to along with a few changes added along the way. I would use Tom’s construction company again and recommend him for anyone who requires a first class service.

Conversions - General- 25 Oct 2025
Steve and his crew (credits to Lionel, Iain, Ayden and his brother) are both professional and efficient. As the team leader, Steve has proven to be exceptionally reliable and always willing to explore different possibilities to ensure the work is done perfectly, within our budget. They helped us knock down three walls, lay new flooring, replaster every wall and some more. We’re grateful to have had his team with us throughout the tight renovation period. They’ve been trustworthy, supportive and clean from start to finish so it has been a real pleasure working with them. To us, their pricing isn’t cheap, but it’s worth what you pay for. Highly recommended!

Conversions - General- 4 Jun 2024
I've been dealing with builders for the last 2.5 years and saw everything, I met so many dodgy people out there who say they know how to do things and eventually screw it up and disappear, that I lost trust in this industry, once I started to work with BBA Developments Ltd I noticed the difference straight away. Adam was professional and kind and explained everything to me. once BBA Developments Ltd began to work, I immediately noticed the difference: everything was done in a top professional way and everything was on time as promised and done to my satisfaction. There were no surprises during the project, there was a very kind contact who was always available to answer my questions quickly. I would recommend hiring BBA Developments Ltd without blinking.

Decking- 14 Jun 2022
James Hynes of JCH Home Improvements have just refurbished our decking area. We thought it was a straight forward job, just to renew the decking and a tidy up BUT the original wood was so rotted the whole area had to be renewed. Joists, upright timbers etc We are thrilled with what James has done, so much more work than anticipated but the end result is fantastic. Would thoroughly recommend JCH Home Improvements and we will be using the again.

What to ask a Saffron Walden extension builder before hiring?

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

An extension builder in Saffron Walden 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 Saffron Walden 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 Saffron Walden?

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 Saffron Walden 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 Saffron Walden 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.
