Project Overview

This integral garage in Cardiff had spent years as storage for bikes, boxes and half-finished DIY. The homeowners wanted a bright, warm room that felt like a natural part of the house rather than an add-on.

We converted the whole garage footprint into a light-filled living space with a herringbone-style floor, full-height glazing to the garden side and a clean, modern finish that flows from the existing hallway.

The Brief

Create usable everyday living space without moving home. The room needed to be warm in winter, quiet, and flexible enough to become a playroom now and a home office or guest room later.

The Challenge

Garage floors sit lower than the house and are rarely insulated. Raising and insulating the floor, replacing the garage door with a proper wall and window, and matching the new level to the hallway were the key technical points.

How We Built It

What We Did, Step By Step

1. Survey & design

A site visit to measure up, check drainage, services and permitted development, followed by a clear itemised quote.

2. Strip-out & structure

Garage door removed, new insulated cavity wall built, openings formed and the floor level prepared.

3. Insulation, electrics & heating

Floor, walls and ceiling insulated to Building Regulations, with new lighting, sockets and heating installed and tested.

4. Finishes & handover

Plastering, flooring, skirting, decoration and a walk-through snagging session before building control sign-off.

Project Highlights

  • Insulated floor, walls and ceiling
  • New double-glazed window and sliding doors
  • Re-wired with LED lighting and plenty of sockets
  • Underfloor-style comfort with radiator heating
  • Matching skirting and architraves
  • Building control certificate included

The Result

The family now has a calm, bright room they use every day. The conversion was finished in under five weeks, passed building control first time and adds genuine, usable floor area to the property.
