HOME & GARDEN

Extra Space Without the Hassle of Moving

A home office, garden room, or outdoor living space gives you the extra room you need without the expense and disruption of an extension or house move. Whether you need a dedicated workspace, a gym, a studio, or a relaxation retreat, our custom-built outdoor rooms offer style, comfort, and year-round usability.


At 4G Building Projects, we design and build bespoke home offices, insulated garden rooms, pre-built garages, and stylish outdoor spaces that are durable, energy-efficient, and tailored to your lifestyle. Whether you’re looking for a fully customised build or a cost-effective pre-built structure, we provide expert craftsmanship with a hassle-free process.

Our Home Offices & Outdoor Building Services

A garden office or outdoor room gives you a private, comfortable space away from the main house, perfect for working from home, exercising, entertaining, or simply unwinding. Built with insulated walls, heating, and high-quality finishes, our home offices and garden rooms are fully weatherproof, secure, and designed to be used year-round.


A custom-built garden room can be used for:


  • A dedicated home office – Create a quiet, distraction-free workspace.
  • A gym or yoga studio – Stay active without leaving home.
  • A hobby room or creative studio – Ideal for music, art, and crafts.
  • A guest room or annex – A stylish, self-contained space for visitors.


Our garden rooms are designed with your needs in mind, with custom sizes, layouts, and finishes to match your style.

Home Offices & Garden Rooms – Work or Relax in Style

We don’t believe in one-size-fits-all solutions. Every garden room or home office is designed around your space, needs, and budget.


  • Fully insulated for year-round comfort
  • Choice of materials, cladding, and roofing
  • Modern features like lighting, heating & internet connectivity
  • Custom layouts for work, relaxation, or multi-use spaces


We work with you to design a functional, stylish, and energy-efficient space that fits perfectly into your garden or outdoor area.

The 3D Design Approach – Tailored for You

A pre-built garage is a fast, efficient way to add secure storage or extra workspace to your property. Whether you need a single garage for parking, a double garage for storage and tools, or a fully insulated unit for multi-purpose use, we provide high-quality, ready-to-install garages that fit your needs.


  • Secure and weather-resistant for vehicle storage
  • Available in a range of sizes and styles

Customer Testimonials

They stepped in at last minute as an urgent job to get us through remedial roofing work from a previous builder who had not obtained necessary building regs and had then needed remedial works to pass certification. We cannot recommend them highly enough.

We were replacing two older sheds and wanted one that covered the same footprint and blended into a more traditional garden. Wouldn’t hesitate to use them again and recommend them to others.

They designed, built and installed a porch and a new set of garage doors for me. Nothing is too much trouble, they kept in touch with me throughout the process, answered any questions I had promptly and worked with me to deliver exactly what we wanted. I would definitely recommend them.
