House Extension Plans in Cardiff
Planning a house extension in Cardiff requires a balance between good design and a clear understanding of local planning requirements.
Properties across the city vary from traditional terraced houses to suburban homes, often with constraints such as conservation areas or neighbouring context to consider.
At Dennis Hellyar Architects, we design house extensions and prepare professional plans for homeowners across Cardiff, helping you move from initial idea through to planning with clarity and confidence.
We also work with homeowners in Swansea, across the Vale of Glamorgan, wider South Wales, Bristol and the South West.
