USE YOUR GARDEN ANNEXE ALL-YEAR-ROUND

That’s why Hawksbeck Annexes utilises Structural Insulated Panels (SIPs) for their construction. Compared to other building techniques, SIPs outperform in both thermal and structural categories, providing exceptional thermal performance that will keep your energy bills low and your annexe suitable for all-year-round use.

Our dedicated architects, project managers, and contractors are here to listen and bring your dream garden annexe to life. From design review to material orders and coordinating specialist teams, our project managers ensure a seamless and stress-free experience.

However, we also regularly install a variety of other high-quality finishes such as tiled floors, engineered wood, cork flooring, and even polished concrete for a sleek, modern look. We’ll help you choose the best flooring option based on how you plan to use the space, your style preferences, and the level of comfort and practicality you need.

At Hawksbeck, we take care of the entire electrical setup for your garden room. This starts with a full electrical survey, including a load test on your home’s consumer unit to determine capacity. We then assess your garden room’s power requirements and specify the appropriate gauge and type of electrical cable.

The cable installation method is tailored to your property and can be:

  • Buried in a trench,
  • Fixed to a fence, or
  • Routed under paving or landscaping.

Our qualified electricians ensure all work meets current building and electrical regulations, so your garden room is safe, efficient, and ready for immediate use.

Yes, at Hawksbeck, we regularly install plumbing for bars, kitchens, and bathrooms in our garden rooms. These features require water supply and waste connections from the main house, and our team are experts in assessing and installing the necessary services. We handle everything from initial planning to final connection, ensuring your garden room is fully functional and compliant with building regulations.

At Hawksbeck, we offer a range of heating and cooling solutions to ensure your garden room is comfortable all year round. The most popular choice among our clients is air conditioning, which provides heating, cooling, and dehumidifying in one efficient and cost-effective unit.

We’re also seeing growing demand for infrared heating panels, which offer a sleek, low-maintenance alternative with fast, radiant warmth. In addition, we install traditional electric radiators, which can be a simple and effective option depending on your preferences and the intended use of the space.

Every Hawksbeck garden room comes with a hardwired data cable installed from your home’s Wi-Fi router directly to the garden room. Inside, we fit a Wi-Fi booster to ensure a strong, reliable signal throughout the space. For added convenience and performance, we also offer hardwired Ethernet sockets for devices like TVs, computers, and gaming consoles –  ideal for remote work, streaming, or online meetings.

Yes, all Hawksbeck garden rooms offer excellent sound insulation as standard, thanks to our high-performance SIPs (Structurally Insulated Panels). These panels naturally reduce noise transfer, making the space quieter and more private.

For clients who require enhanced soundproofing – such as for music production, podcasting, or use as a sound studio – we collaborate with specialist acoustic engineers to install the latest sound-deadening technologies. We’ve successfully delivered fully soundproofed garden studios for professional recording artists and content creators.

At Hawksbeck, we offer a full range of modern lighting options to suit your style and how you intend to use your garden room. Choices include:

All installations are completed to a high standard and in line with current building regulations.

Proper ventilation is essential to ensure a healthy, comfortable environment inside your garden room. At Hawksbeck, we design every space to include sufficient natural and mechanical ventilation based on its intended use.

This typically includes:

  • Opening windows and doors for natural airflow
  • Trickle vents as standard are built into windows and doors for passive background ventilation
  • Optional mechanical ventilation systems for rooms with high humidity, such as bathrooms or kitchens

For spaces like gyms, studios, or annexes with water facilities, we ensure compliance with Building Regulations Part F, which governs ventilation performance. We tailor the ventilation approach during the design phase to ensure optimal air quality and comfort year-round.

Hawksbeck garden rooms are built using high-quality, durable materials designed for year-round use with minimal maintenance. To keep your garden room in excellent condition, we recommend:

  • Regularly cleaning windows and doors to prevent dirt build-up
  • Wiping down cladding (especially timber) annually to maintain its finish — natural wood may require re-oiling or staining every few years
  • Checking roof gutters to ensure no leaf blockages
  • Maintaining the surrounding area — trimming nearby trees and shrubs to prevent overgrowth

If you’ve opted for low-maintenance finishes like composite cladding, even less upkeep is needed. We also offer aftercare advice and optional maintenance services for long-term peace of mind.

At Hawksbeck, we stand behind the quality of our work with comprehensive, insurance-backed warranties to give you complete peace of mind:

  • A 10-year insurance-backed structural warranty from the Independent Warranty Association (IWA)
  • Independent warranties on all doors and windows, provided by our specialist suppliers/installers
  • Roof warranties backed by the manufacturers, subject to the specific roofing system installed
  • Our composite cladding includes an extended manufacturer’s warranty for added protection
  • Luxury vinyl flooring comes with its own extended warranty for long-lasting performance
