We’re delighted to share the transformation of Trenans, a once modest bungalow in the popular area of St Agnes, into a light-filled, contemporary and energy-efficient family home.

Before
The original property offered two bedrooms and a study, sitting on a generous plot with ample parking and three garages. While clearly well loved, the house was in need of updating throughout. The layout felt constrained, with small kitchen and living areas that did not make the most of the available space or the connection to the garden. Heating was provided by a basic electric system, and the building envelope offered limited insulation.

After
A rear extension and full eco-retrofit have transformed Trenans into a spacious and future-ready three-bedroom home. The reconfigured layout now features a bright open-plan kitchen and living space, where a large picture window frames views of the garden and fills the room with natural light. Bifold doors open out from both the kitchen and living room, creating a seamless connection to the outdoor terrace and turning the heart of the home into a versatile indoor-outdoor family space.

The rear extension and existing back elevation have been clad in black timber to create a crisp, contemporary appearance. The rest of the house has been externally insulated and re-rendered, significantly improving thermal performance.

A new air source heat pump now provides low-carbon heating and hot water, and the existing garage has also been reclad to sit comfortably within the updated context. The surrounding garden has been re-landscaped to provide a welcoming and functional outdoor area for family life.

What was once a compact bungalow is now a generous and energy-conscious home, carefully updated to meet the needs of modern living.
