Single-Storey Extensions

Functional, visually stunning, built to last.

Single-storey extensions are a practical way to increase living or operational space without compromising on flow or design. Whether you’re expanding a kitchen, lounge, or office, our builds are designed to fit your property’s architecture and improve day-to-day functionality.

• Maximise Internal Space and Natural Light

  Our team works with you to design layouts that improves flow of the space to enhance daily use. We'll use clever storage techniques and strategic window placement to make the most of every square metre.

• Structural Integrity

  We construct robust foundations tailored to ground conditions and load requirements. Every build includes comprehensive damp-proofing to protect against water ingress and structural degradation.

• Premium Insulation, Glazing, and Weather Protection

  Our extensions meet high performance standards for thermal efficiency. We install insulation, glazing, and cladding materials that keep interiors comfortable while reducing long-term energy costs.

• Integration With Existing Services Including Electrics, Heating, and Plumbing

  We ensure seamless integration with your home’s utilities. Our in-house specialists manage all required connections and upgrades to maintain full functionality.

• Clean Transition Between New and Existing Structures

  We match materials, floor levels, and finishes to create a visually smooth and cohesive extension. The result is a space that looks and feels like it has always been part of the property.
