Project Overview

A cramped, dark kitchen was the heart of this Penarth home — and the part the family used least. A single-storey rear extension gave them space to cook, eat and relax together.

A glazed roof lantern floods the room with light while large sliding doors connect the interior directly to the garden, making the room feel twice its true size.

The Brief

Create an open-plan kitchen and dining area that feels connected to the garden, with materials that match the existing house so the extension looks original.

The Challenge

Opening up the back of an existing home means careful structural work. Steel beams, temporary support, foundations and drainage all had to be coordinated while the family kept living in the house.

How We Built It

What We Did, Step By Step

1. Design & approvals

Drawings, structural calculations and the necessary approvals were prepared before work began.

2. Groundworks & structure

Foundations, drainage, masonry and steelwork completed, with the roof lantern installed and weathertight.

3. Services & first-fix

Electrics, underfloor heating pipework and plumbing installed ahead of plastering.

4. Kitchen & finishes

Flooring, kitchen installation, decoration and final snagging with the homeowners.

Project Highlights

  • Glazed roof lantern for natural light
  • Wide sliding doors to the garden
  • Underfloor heating throughout
  • Brickwork matched to the original house
  • Structural steelwork fully certified
  • Building control sign-off

The Result

The family gained a large, light-filled kitchen-diner and a direct link to the garden. The extension adds value, living space and a room everyone wants to spend time in.
