Sidmouth - Home Office & Guest Bedroom

Sidmouth Garage Conversion: Detached Garage Transformed into Modern Home Office & Guest Bedroom

This recent Sidmouth garage conversion perfectly demonstrates how a detached outbuilding can be turned into a high-quality, multi-use living space. The clients wanted to make better use of their large detached garage — converting it into a comfortable home office and guest bedroom while keeping the exterior in harmony with their beautiful Sidmouth garden setting.

Project Overview

Location: Sidmouth, Devon
Original Space: Detached double garage (approx. 30m²)
Converted To: Dual-purpose home office and guest bedroom
Duration: 6 weeks
Client Brief: Create a stylish, insulated workspace and a welcoming guest room within an existing detached structure, maintaining privacy and year-round comfort.

Design & Planning

The homeowners approached Devon Garage Conversions looking for a flexible solution that combined professional workspace with family accommodation. Our design team produced a layout that delivered both practicality and a touch of luxury:

Half the building converted into a quiet, well-lit home office with custom desk area, fibre internet connection, and ample power points.

The other half transformed into a bright double bedroom with en-suite shower room and built-in wardrobe.

A central connecting lobby linking both spaces with direct garden access.


Externally, the garage retained its original pitched roof and brickwork, but new anthracite-grey aluminium windows and a matching entrance door modernised its appearance.

Construction Highlights

The Devon Garage Conversions team handled every stage, from design approval to completion. Key works included:

Full structural upgrade with damp-proofing, floor insulation, and internal studwork.

Installation of high-performance insulation in walls, roof, and floor to achieve excellent energy efficiency.

New plumbing and drainage for the en-suite bathroom.

Complete electrical rewire, LED lighting, and smart heating control.

Plastered and decorated interiors with engineered oak flooring for a warm, professional look.

External landscaping to create a private walkway and patio outside the new entrance.


Because the garage was detached, careful attention was paid to ensuring proper utilities, fire safety, and ventilation. The result was a fully compliant, habitable space ready for everyday use.

The Result

The completed Sidmouth detached garage conversion is a stunning example of smart design and craftsmanship. The office side offers a quiet retreat for focused work, filled with natural light and views of the garden. The adjoining bedroom and en-suite provide a peaceful guest space that feels entirely self-contained — ideal for visitors or even as a future holiday let or studio annexe.

The clients were delighted:

> “It’s completely changed how we use our home. We now have a beautiful workspace and a private guest room — Devon Garage Conversions were professional, efficient, and the finish is outstanding.”
