We're very happy with our new garden office which was designed & constructed by Richee Carpentry. The construction was quick & efficient and communication was clear and timely throughout, last minute changes were accommodated on the fly such as us finding a skylight and asking for it to be installed. The trades involved were polite and professional and the living roof is just fabulous!

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!

What to ask a Penzance extension builder before hiring?

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

An extension builder in Penzance 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 Penzance 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 Penzance?

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 Penzance 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 Penzance 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.
