House Extension Plans in Bristol

Planning a house extension in Bristol often involves working within a well-established urban context, with many properties located in conservation areas or forming part of historic streetscapes.

Careful design and clear planning drawings are essential to achieve approval while respecting the character of the surrounding area.

At Dennis Hellyar Architects, we prepare professional house extension plans for homeowners across Bristol, helping you move from initial idea through to planning approval with clarity and confidence.

We work with homeowners across the South West as well as in Cardiff, Swansea, across the Vale of Glamorgan and wider South Wales.
