Excellent service provided by EGM Property Services. Elliott and his team were reliable, trustworthy and produced a top quality finish on the house. He provided new fascias and cladding plus repointed the house and chimney stack. He added detail to the facias to keep in character of the age of the house - above and beyond what was expected. I would definitely recommend EGM property services.

Extension Builder in Derby
I operate my business with a small team of experienced men. We produce quality work efficiently, and at affordable prices. We are reliable, trustworthy and turn up when expected. We only take on one job at a time, and attend site every day until completion. We have a dedicated engineer, gas plumber and electrician to call on when needed. Much of my work comes from word of mouth recommendations. We give an extended warrant and have many good references.

Extensions- 15 Jul 2025
Home extension completed by Mick, & we are absolutely thrilled with the results. From the very beginning, Mick was professional, approachable, & incredibly knowledgeable. He took the time to understand exactly what we wanted and offered brilliant advice along the way. One of the things that really stood out was Mick’s practical and creative ideas some of his suggestions actually saved us money without compromising on quality or design, which we really appreciated. The quality of the work is excellent everything was completed to a high standard, & the attention to detail really shows. Mick & his team were reliable, punctual, & kept the site tidy throughout the project, which made the whole experience so much easier for us. He kept us informed at every stage & delivered exactly what he promised, on time & within budget. The extension has transformed our home, & we honestly couldn’t be happier. We wouldn’t hesitate to recommend Mick to anyone looking for a trustworthy and skilled builder.

I can recommend Jake and 3Sixty Property Solutions without hesitation. From start to finish Jake and his team completed the project in a very professional manner. Having taken the brief he designed and built the side extension around and existing structure to give a modern addition to our bungalow. It wasn’t without its problems but Jake found the solutions. His philosophy of completing a job to the customers satisfaction was most welcome. I will certainly use 3Sixty Property Solutions again.

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

An extension builder in Derby 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 Derby 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 Derby?

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 Derby 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 Derby 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.
