Teignmouth - Guest Suite Garage Conversion

Teignmouth Garage Conversion: Turning an Unused Space into a Coastal-Inspired Guest Suite

For this recent garage conversion in Teignmouth, Devon Garage Conversions were commissioned to transform a cold, cluttered double garage into a bright and welcoming guest suite — ideal for visiting family and friends. With Teignmouth’s beautiful coastal setting, the design focused on light, comfort, and a relaxed seaside feel.

Project Overview

Location: Teignmouth, Devon
Original Space: Double garage (approx. 32m²)
Converted To: Self-contained guest suite with bedroom, shower room, and kitchenette
Duration: 6 weeks
Client Brief: Create a private, comfortable living space for family guests with a beach-inspired aesthetic and independent access.

Design & Planning

The homeowners loved their property’s location overlooking the Teign Estuary but needed additional accommodation that could double as an Airbnb-style guest suite in future. Our design team developed a plan that balanced practicality with charm:

Open-plan bedroom and lounge area with coastal colour palette

Compact en-suite shower room with modern fittings

Kitchenette for guest convenience

Independent external access door and upgraded windows for light and ventilation


We submitted detailed plans to Building Control and worked closely with the clients to finalise layout, lighting, and finishes that suited their taste and future-proofed the space for multi-use living.

Construction Highlights

From the first day on site, our focus was on structural integrity and comfort:

Removal of old garage doors and installation of insulated cavity wall with coastal-render finish to blend with the property’s exterior

Installation of new foundations and drainage for the en-suite

Full insulation upgrade to exceed Building Regulations and provide year-round warmth

LED lighting, soundproof plasterboard, and vinyl click flooring chosen for durability and easy maintenance

A stylish composite entrance door with side window providing natural light and a sense of independence

Addition of electric underfloor heating for a modern, comfortable finish


Our skilled team managed all plumbing, electrics, and joinery in-house — ensuring smooth coordination and a fast turnaround, despite challenging coastal weather during the build.

The Result

The completed Teignmouth garage conversion is now a bright, airy guest suite that perfectly complements the main home. Soft coastal tones, oak detailing, and natural light create a relaxing retreat just steps from the main house. The addition of an en-suite and kitchenette gives guests privacy, while the homeowners now have flexible space for family, friends, or short-term lets.

The clients shared their feedback:

> “It’s completely transformed our home. The space feels luxurious and calm — Devon Garage Conversions delivered exactly what we hoped for.”
