An extension is often the best solution to a need for more space at home. Although less of an upheaval than moving house, an extension can still be a stressful process. We have over 10 years of experience of planning and implementing extensions so we know what makes the process run smoothly.

We aim to complete your extension with as little disruption to your day to day lives as possible. We follow the architect plans or can source an architect for you to help you achieve your vision. From sourcing the right materials from our network of trusted suppliers to organising the removal of leftover materials on completion, you can leave it all in our capable hands.

We provide home extensions services in Swansea, Llanelli and the surrounding areas.

Why we’re different

We pride ourselves on our positive feedback from previous clients, who have enjoyed working with us because our approach to:

  • Consultation – we will follow the plans of the architect and we’ll give our input on our areas of expertise e.g. materials and specification.
  • Communication – there’s no two ways about it – extensions are stressful. We try to reduce as much stress as we can by keeping clients informed about timescales and costs the whole time.
  • Project management – we work within a network of tradespeople that we know and trust. We always choose the best people for the job who are as reliable and cost effective as we are.
