Building your ideal extension, without the stress
When you want to add space and value to your home, Oak House Design & Build Ltd in St Albans brings over 20 years’ experience to every house extension project. We work with single-storey builds, larger domestic extensions, and multi-room plans, always using local tradespeople who know the area. Our approach is straightforward: we handle project coordination so you can focus on how you want to use your new space. Many customers come to us with planning permission already sorted, and we’re happy to support you through the next steps. By working closely with you, we make sure your extension feels like a natural part of your home. With us, you get a flexible and honest team who keep your priorities at the heart of the build.
How we manage your extension project
We take on larger domestic works, including projects valued around £100,000, ensuring you have the right expertise for significant changes. Our team coordinates every detail, from groundwork to finishing touches, staying in touch with you throughout. We’re used to working from approved permissions, so you avoid costly setbacks or delays. Every member of our trades team lives locally, meaning quick responses and reliable support. We adapt our process to what your project actually needs, rather than sticking to a rigid template.
