Design Build Versus Builders: Which Fits Your Home?
September 24, 2026Planning an extension is a major investment. While most projects go smoothly, there are common pitfalls that can derail your budget and your timeline. Learning from these mistakes early on can save you thousands.

Avoiding the Pitfalls
- Underestimating Structural Costs: Don’t focus only on the finish. Structural elements like foundations and steel beams are the most critical—and costly—part of the build.
- Ignoring Party Wall Agreements: Failing to notify your neighbours early can stop your project dead in its tracks.
- Focusing Only on Price: The cheapest quote is rarely the best. Always evaluate based on the builder’s experience, communication, and project management skills.
A successful extension is a marathon, not a sprint. By working with a specialist team like MBT Group, you ensure that every detail—from planning to plumbing—is managed with professional care.
