Single and two-storey extensions in Cornwall and Devon

A single-storey extension can create space for a kitchen and dining area, a living room, a bedroom or somewhere to work. It can also bring more daylight into your home and improve the connection with your garden.

We consider the new space alongside the existing rooms, looking carefully at layout, roof design, glazing and how you will move through the house.

A two-storey extension can provide additional space on both floors, perhaps combining a larger kitchen or living area downstairs with bedrooms and a bathroom above.

We explore how the extension could sit comfortably alongside your existing home, considering its proportions, roofline, materials and relationship with neighbouring properties. Inside, we look at how the new rooms connect with the existing layout, including stairs, landings and circulation.

Sometimes the best solution combines an extension with changes inside the house. Moving a doorway, rethinking a hallway or changing how rooms connect can make a significant difference to the result.

We help you consider how much additional space you need and where alterations could make better use of what is already there. This allows the design and budget to focus on the changes that will be most valuable to you.

An extension needs to work with the building you already have. We consider structure, drainage, insulation, heating and daylight as the design develops, alongside the finishes and details that help the spaces feel connected.

Our in-house skills cover design, planning, energy assessment, technical detailing and interiors. We work collaboratively and can coordinate with structural engineers and other trusted specialists where their input is needed.

Throughout the process, we help you understand the options and balance your priorities with your budget, whether you are planning a modest addition or a more substantial transformation.
