Timber frame extensions: 5 tips for choosing the right builder
Architectural Design Insights | Alistair Crerar
How to find a trusted timber frame extension builder for your North East home and avoid costly mistakes.
A well-built timber frame extension can transform the way you live, adding light, space, and value to your home. But the quality of the result depends heavily on the builder you choose.
If you live in Newcastle upon Tyne, Northumberland, or North Tyneside — and are planning a significant investment in your property — here are five expert tips to help you select a builder who can deliver to the highest standards.
1. Research Beyond the Basics
Don’t just pick the first name from a search result. Start by looking at local timber frame specialists who have a proven track record with projects of a similar size and complexity to yours. Ask trusted friends or neighbours for recommendations, then review online feedback carefully — paying attention to consistency over time. Membership of recognised trade associations such as the Federation of Master Builders or National Federation of Builders is a good sign of professionalism.
2. Review Their Portfolio with a Critical Eye
A strong portfolio should show not just attractive finishes, but evidence of sound construction, attention to detail, and consistent quality across multiple projects. Ask to see examples of timber frame extensions similar to yours in scale and style — ideally in person, not just in photos. Look for work that integrates seamlessly with existing homes, especially in older or character properties.
3. Ask About Their Quality Assurance Process
A reputable builder will be able to explain how they maintain standards throughout the build. This should include staged inspections, documented checks, and a clear process for resolving issues. Ask whether they offer a written warranty on workmanship — a sign that they stand behind the quality of their build long after completion.
4. Read Every Detail of the Quotation
High-quality timber frame extensions require premium materials and skilled labour — and this should be reflected in a clear, detailed quotation. Beware of vague or incomplete quotes that leave too much open to “extras.” Clarify exactly what is and isn’t included, and confirm that materials meet the specifications your design calls for.
5. Check Qualifications and Insurance
Every contractor and subcontractor on site should hold up-to-date trade qualifications, with evidence available for you to review. Insurance cover — including public liability — is essential for protecting you and your investment. Don’t be afraid to ask for proof before work begins.
