Cullompton - Extra Bedroom Garage Conversion

Cullompton Garage Conversion: Creating a Beautiful New Bedroom

When a growing family in Cullompton, Devon needed more space without the cost of moving house, Devon Garage Conversions stepped in with the perfect solution — a stylish and practical garage-to-bedroom conversion. What was once an unused single garage is now a bright, comfortable double bedroom with en-suite potential, seamlessly integrated with the main home.

Project Overview

Location: Cullompton, Devon
Original Space: Single attached garage (approx. 18m²)
Converted To: Spacious double bedroom with built-in storage
Duration: 4 weeks
Client Brief: Transform the cold, cluttered garage into a warm, fully insulated bedroom for a teenager — matching the interior design and comfort of the main house.

Design & Planning

Our process began with a detailed consultation to understand the family’s needs. The clients wanted a space that felt like a natural extension of their home, not a converted garage. Working closely with Building Control, our team designed a plan that delivered:

Full insulation upgrade (walls, floor, and ceiling) to exceed thermal standards

A new window and brick-infill frontage to match the existing property façade

Recessed LED lighting and contemporary sockets with USB charging

A custom built-in wardrobe and storage alcove to maximise usable space


Every Cullompton garage conversion we complete starts with ensuring the structure is sound, watertight, and energy-efficient. This one was no exception — we upgraded the foundations and added a damp-proof membrane and vapour barrier before laying insulated screed flooring.

Construction Highlights

Removal of the existing garage door and installation of a matching brickwork wall with an energy-efficient uPVC window

New stud walls and ceilings lined with 100mm insulation

Complete electrical rewire to suit the new layout and lighting plan

Plastering, skirting, and paint finish to mirror the main house interior

Acoustic insulation to maintain quietness between the new bedroom and adjoining living areas

Installation of electric radiator with smart control, allowing independent temperature adjustment


Throughout the build, the Devon Garage Conversions team ensured minimal disruption, maintaining access to the property and keeping the site tidy each day.

The Result

The transformation is remarkable. The once draughty garage is now a cosy, modern bedroom with soft lighting, a comfortable layout, and a warm, homely feel. The family gained an essential extra room without extending outward — adding both practical space and value to their home.

The clients shared their feedback:

> “We’re delighted with the result. It’s impossible to tell it was ever a garage — it feels like it’s always been part of the house. Devon Garage Conversions made everything effortless.”



Why a Cullompton Garage Conversion Makes Sense

Instant extra living space without losing garden area

Lower cost than a full extension or loft conversion
