Garage Conversions in Bexley & Kent

Transform Unused Garage Space into a Valuable New Room
A garage conversion is one of the most cost-effective and convenient ways to add extra living space to your home. Whether your garage is underused, outdated, or simply no longer needed for parking, converting it into a functional room can dramatically improve both comfort and practicality — without the need for major structural work or large construction costs.
Many homeowners across Bexley, Bexleyheath, Sidcup, Dartford, Eltham, Orpington, Welling, and wider Kent are choosing garage conversions as a smart alternative to extensions. In many cases, a garage conversion can be completed faster, with less disruption, and at a significantly lower cost than other home improvement projects — all while adding meaningful value to your property.
At P J Dunbar Builders Ltd, we’ve been converting garages into high-quality living spaces for more than 30 years. Whether you want a home office, an extra bedroom, a gym, a playroom, a utility room, or a fully self-contained annexe, our experienced team manages every stage of the project — from the initial assessment through to design, construction, electrics, plumbing, insulation, and finishing.
A garage conversion offers one of the highest returns on investment, and with the right builder, the transformation can be seamless.
Types of Garage Conversions We Build
Every home — and every garage — has different potential. Our job is to help you unlock it. We’ll assess your space, understand your goals, and recommend a conversion style that suits your home, layout, budget, and long-term plans.






Benefits of a Garage Conversion
A Cost-Effective Way to Add Valuable Living Space
Compared to house extensions or loft conversions, garage conversions are usually more affordable because the main structure already exists.
This means less construction work, fewer materials, and shorter build times. For a relatively modest investment, you can create a completely new room that improves day-to-day comfort and expands your living space dramatically.
Increase Property Value with Minimal Disruption
A well-designed garage conversion can significantly increase the value of your home, especially in areas where living space is in high demand.
Buyers prioritise practical layouts, additional bedrooms, home offices, and improved ground-floor functionality — all of which a garage conversion can provide. Because these builds typically involve less upheaval than major extensions, you gain value and usability with far less disruption.
Create a Room Designed Around Your Lifestyle
Many families find that their home works perfectly — except for one missing room.
Whether you now work from home, have a growing family, need more storage, or want a dedicated space for hobbies or exercise, a garage conversion allows you to design a room that fits your life exactly. Instead of compromising or moving house, you adapt your home to meet your real-world needs.
A Faster, Cleaner, and Smoother Build Process
Garage conversions rarely require extensive structural work, meaning the project can progress quickly and with minimal disruption to your daily routine.
In most cases, homeowners can remain living in the property throughout the build. By transforming an existing space rather than constructing a new one, garage conversions offer a simple, straightforward route to gaining the extra room you need.
Got Questions About Garage Conversions?
If you're unsure where to start or want to know whether your garage is suitable for conversion, we’re always happy to offer friendly, honest advice.

Our Garage Conversion Process
After more than 30 years of working in Bexley, Kent, and South East London, we’ve built a smooth, reliable process that keeps your project organised and stress-free from the first conversation to the final handover.
Consultation & Early Advice
We begin with an informal discussion about your goals, whether that’s creating a bedroom, home office, gym, or extended living space. We’ll help you understand what’s possible with your garage, how the conversion might impact your layout, and what options best suit your property and budget. This stage gives you clarity and confidence before committing to anything.
Detailed Survey & Feasibility Assessment
If you'd like to move forward, we carry out a full survey of your garage to assess its structure, foundations, insulation potential, ceiling height, and integration with the main home. We’ll also discuss whether planning permission is required (in most cases it isn’t), as well as building regulation requirements such as fire safety, thermal efficiency, and ventilation. This ensures that everything we build meets modern standards and performs well long term.
Design, Drawings & Building Regulations Approval
Garage conversions must meet specific building regulations, including thermal upgrades, structural integrity, and fire safety standards. We work with your chosen designer or our trusted architectural partners to prepare drawings that are not only visually appealing but also fully compliant. We handle building control submissions and liaise with inspectors to ensure a smooth approval process from start to finish.
Pre-Construction Planning
Before work begins, we outline the full scope of the project, including materials, timelines, insulation requirements, electrical layouts, plumbing locations, and finishing options. We believe in total transparency, so you’ll always know what to expect at each stage. This planning phase ensures a clean, organised build with no unexpected disruptions.
Construction, Conversion & Finishing
During construction, we transform your garage into a warm, comfortable living space that blends seamlessly with the rest of your home. This often includes raising the floor, adding insulation, installing new windows and doors, fitting electrics and heating, upgrading walls and ceilings, and completing all plastering, carpentry, and finishing touches. A dedicated project lead keeps you updated throughout the build, ensuring quality and consistency at every stage.
Final Approval, Handover & Aftercare
Once construction is complete, we walk through the finished room with you to ensure everything meets your expectations. We handle building control sign-off, complete any final adjustments, and ensure you’re fully satisfied with the work. Even after the project is finished, we’re always here if you need follow-up advice, support, or future improvements.

Garage Conversion FAQs
In most cases, garage conversions fall under permitted development and do not require full planning permission.
However, this depends on whether your property has previous extensions, whether you live in a conservation area, and whether the conversion changes the building’s external appearance.
We’ll assess this during your site survey and guide you through any required applications.
Costs vary depending on the size of your garage, the extent of structural alterations, and the type of room you’re creating.
For example, adding plumbing for a utility room or bathroom will affect the cost differently than creating a standard bedroom or home office.
After a site visit, we provide a clear, fixed, itemised quotation so you know exactly what to expect.
Many homeowners choose to integrate built-in storage during the conversion, or add outdoor storage solutions such as a shed.
We can help you explore practical alternatives so you don’t sacrifice storage unnecessarily.
Yes — garage conversions often add significant value, especially when creating practical spaces such as home offices, bedrooms, or extended living areas.
In many cases, the value added exceeds the cost of the project.

A typical garage conversion takes 2–5 weeks, depending on the level of structural work and the complexity of the new room.
Because much of the work focuses on internal changes — insulation, electrics, heating, floors, and plastering — the process is usually faster and smoother than larger construction projects.
