Outbuildings & Garden Rooms in Bexley & Kent
Outbuildings & Garden Rooms in Bexley & Kent
Outbuildings and garden rooms are one of the most versatile ways to add valuable space to your property without altering the main structure of your home. Whether you’re looking for a quiet home office, a gym, a studio, a garden lounge, or additional storage, a well-built garden room offers a practical, comfortable solution that works year-round.
At P J Dunbar Builders Ltd, we’ve been designing and constructing high-quality outbuildings and garden rooms across Bexley, Bexleyheath, Sidcup, Dartford, Eltham, Welling, Orpington, and the wider Kent area since 1994. As a long-established, family-run building company, we focus on building structures that are solid, well-insulated, and built properly from the ground up — not temporary or flimsy installations.
From simple garden rooms to fully serviced outbuildings with electrics, insulation, and heating, our experienced team manages every stage of the build with care, precision, and clear communication.
Garden Rooms & Outbuilding Options
Every garden and every household is different, which is why we tailor each outbuilding to suit your space, usage, and long-term plans. During the early stages, we help you understand what’s possible and design a structure that fits naturally within your garden.
Benefits of Adding a Garden Room or Outbuilding
Gain Valuable Space Without Altering Your Home
An outbuilding allows you to add usable space without extending your house or disrupting internal layouts. This is ideal for homeowners who want flexibility while keeping their main living areas unchanged.
Increase Property Value and Appeal
Well-built garden rooms are increasingly attractive to buyers, particularly those looking for home office space or flexible living solutions. A professionally constructed outbuilding can significantly enhance your property’s appeal and long-term value.
Designed for Comfort and Year-Round Use
Unlike basic garden structures, our outbuildings are built with proper foundations, insulation, electrics, and weather protection — ensuring they remain warm, dry, and comfortable throughout the year.
Custom-Built to Suit Your Lifestyle
Every outbuilding is designed around how you intend to use it. From layout and glazing to insulation and finishes, the space is tailored to your needs rather than a one-size-fits-all solution.

Our Outbuilding & Garden Room Process
With more than 30 years of experience, we’ve developed a clear, well-managed process for designing and building high-quality outbuildings and garden rooms that are practical, durable, and built to last.
Whether you’re creating a home office in a Bexley garden, adding a leisure space to a property in Kent, or constructing a standalone outbuilding for a family home in Bexleyheath, our approach ensures clear communication, careful planning, and consistent quality from the first conversation through to final handover.
Initial Consultation and Advice
We begin with a conversation about how you want to use the space, your budget, and any ideas you already have. This allows us to recommend practical solutions that suit both your garden and your long-term plans.
Site Survey and Feasibility Assessment
We assess garden access, ground conditions, boundaries, drainage, and services to ensure the proposed outbuilding is practical and structurally sound.
Design, Planning and Regulations
Many garden rooms fall under permitted development, but this depends on size, height, and location. We confirm whether planning permission or building regulations approval is required and handle the process where necessary.
Pre-Construction Planning
Before work begins, we finalise designs, materials, timelines, and build sequencing — ensuring clarity and minimal disruption.
Construction and Installation
Our skilled, long-standing team carries out all groundwork, foundations, framing, insulation, roofing, electrics, and finishing. Every stage is completed with care and quality control.
Final Checks and Handover
Once complete, we walk you through the finished space, ensure everything meets expectations, and remain available for aftercare or future improvements.
