What makes Durham Special?


Durham is a local government district as well as a historic county in the North East of England and located along the North Sea coastline with a combination of picturesque landscape and cultural significance. Though the unitary authority and the historic county are not congruent, the boundaries of the latter span the northeast Tyne and Wear, as well as the North Sea; though close neighbours are Hartlepool, Stockton-on-Tees, and Darlington.

 

The area of the county is nowadays made up of such districts as Chester-le-Street, the city of Durham, Darlington, Hartlepool, and a part of the Borough of Stockton-on-Tees. Durham is a perfect mix of history, friendly people, and beautiful countryside. Durham is one of these cities that have a perfect combination of tradition and modernity, thanks to its charming cathedral, student life.

More about us

Basement Conversion Durham

At Extension Architecture, our team of expert Durham architects is dedicated to transforming your vision into reality. Specialising in a range of projects—from house and basement extensions to loft and garage conversions—we guide you through every stage, from initial design concepts to planning, building control, and final realisation. A Durham basement conversion is a fantastic way to enhance your home’s space without expanding outward. It can provide a new bedroom, office, or even a home cinema, adding significant value and functionality. Often, these projects don’t require planning permission, unless you’re making major structural changes or altering the exterior.

 

We handle everything from meticulous site assessments to ensuring compliance with local regulations, especially considering conservation and heritage aspects. With a near 100% success rate, our team ensures that every project aligns perfectly with Durham county’s unique planning regulations and the historical context of your property. We stay updated on local planning changes and learn from neighbouring approvals and refusals, ensuring our approach is always informed and effective.

In-house Structural Engineer

In-house Structural Engineer

Our in-house structural engineer—an advantage that only 1 in 20 firms can offer. This is crucial, as significant time is often lost consulting multiple specialists, which can lead to additional costs. With a structural engineer on our team, we ensure a fully collaborative and seamless design-build process, minimizing contingencies and preventing design inaccuracies.

Turnkey Approach

Turnkey Approach

We provide support throughout the entire building process, embracing a ‘turnkey approach’ to ensure a smooth and efficient project from start to finish.
