Handyman- 7 Mar 2021
It was a pleasure to have Sam fit a new 2-level heavy-duty shelf exactly to my specifications. He carefully went over the details, produced some drawings for me to choose from and then made and painted a solid shelf with supports to match the handles of the cupboards below. I am delighted with the result. It is really splendid. Thank you, Sam!

Carpentry- 11 May 2026
Adam did a fabulous job replacing all the internal doors and the floors in my kitchen and hallway. It has transformed my home. He is friendly and professional and scrupulously honest, always letting us know when additional work would affect the estimate (which he absolutely stuck to otherwise). He worked round supply problems brilliantly and always kept us informed about when he would be working. He was a pleasure to have around and I will definitely be using him again.

Extensions- 1 Dec 2016
Can only say good things about Will and his team. They were polite, considerate and friendly, timely and tidy. Will project managed the whole first floor dormer extension which he did better than we could hope for, taking all the worry out of the work. He had great attention to detail and took on board everything we said or asked for. Will was thorough in his preparation of the estimate and we were really only over because our old house threw up extras and we opted for additional work. He kept us informed of what the extras were likely to be at all times and always checked with us first. We felt he was approachable and it was easy to discuss any queries with him. We are extremely pleased with the quality of finish and the end result. I would not hesitate to recommend Milne Construction.

Extensions- 20 Jul 2024
Andy has just completed a large extension and renovation of my house and I can't recommend him highly enough. His original quote was very fair, and he kept me abreast of any changes that occurred as we went along. Andy (and his colleague Darren) worked very hard to make our ideas a reality. He offered creative solutions to issues as they came up, and was even happy to visit during the weekends to get the last bits of snagging done. His tiling in particular is exceptional (3 bathrooms done), and he even turned his hand to building us some built-in wardrobes and a huge bookcase. He's honest, reliable, hardworking, knowledgeable, and fun to have around. If you've got a building job I'd seriously consider adding him to your shortlist. You won't regret it.

What to ask a Penryn extension builder before hiring?

Before hiring an extension builder in Penryn or extension building company in Penryn, 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 Penryn?

An extension builder in Penryn 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 Penryn 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 Penryn?

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 Penryn 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 Penryn 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
