Rear Extensions in Surrey & Hampshire

Open your home to the garden with a beautifully crafted rear extension, designed around your lifestyle.

Rear Extensions

Seamless Indoor-Outdoor Living

A rear extension is the single most popular type of home extension in the UK, and it is easy to see why. Extending into the garden creates an instant connection between your interior living space and the outdoors, flooding your home with natural light and dramatically increasing the usable floor area.

Whether you are dreaming of a stunning open-plan kitchen-diner, a family living room that opens onto a patio, or a dedicated home office with garden views, Hogs Back Builders can design and build the perfect rear extension for your Surrey or Hampshire property.

Design Features We Specialise In

  • Full-width bi-fold and sliding doors opening to the garden
  • Roof lanterns and skylights to maximise natural light
  • Open-plan kitchen, dining and living arrangements
  • Underfloor heating throughout the new space
  • Frameless glazing for a contemporary finish
  • Matching brickwork and external finishes to blend seamlessly

Popular Features

Design Options for Your Rear Extension

  • Bi-Fold & Sliding Doors

    Full-width aluminium bi-folds or sliders that open your living space directly onto the garden.

  • Roof Lanterns

    Structural glass roof lanterns flooding the centre of deep-plan extensions with daylight.

  • Underfloor Heating

    Wet or electric UFH systems installed beneath tile, stone, or engineered-wood floors.

  • Vaulted Ceilings

    Open rafter or vaulted ceiling designs that add drama and a sense of volume.

  • Integrated Lighting

    Recessed downlights, feature pendants, and external soffit lights planned from the start.

  • Garden Integration

    Matching patio, decking, or landscaping so the extension and garden work as one space.

Single-Storey vs. Two-Storey Rear Extensions

  • Single-Storey Rear Extensions

    Single-storey rear extensions are the most common choice, offering a relatively quick build process, significant living space gains and the opportunity to incorporate large glazed doors and skylights. Many fall within Permitted Development rights, meaning no planning application is required.

  • Two-Storey Rear Extensions

    Two-storey rear extensions provide even greater space at both ground and first-floor levels, ideal for adding a bedroom and bathroom above the new ground-floor room. These generally require planning permission but offer an excellent return on investment.
