Pent Haus provides self-build garden room kits designed for flexibility, offering customisation options for size, door and window configurations, and internal finishes. Their intuitive online configurator allows you to design your garden room in just three minutes. Once ordered, kits are delivered within three weeks and can be installed by two people in only three days.
Building your own garden room is not only highly rewarding but also cost-effective compared to fully installed options. Pent Haus makes it easy to explore pricing details for your customised design via their website.
Why Pent Haus Kits Stand Out
Pent Haus garden room kits are engineered for both functionality and style. Unlike many competitors, Pent Haus uses CNC technology to precision-cut SIP panels, ensuring seamless, invisible joints for a sleek, modern look.
The concealed electrics in Pent Haus kits replicate household standards, avoiding the surface-mounted wiring seen in many other kits. This enhances the room’s aesthetic while maintaining practicality.
Available in a range of sizes, from 3m to 5.4m in width and 2.6m to 3.8m in depth, these garden rooms can be tailored to your exact requirements. Pent Haus also offers unique features, such as the ability to add partition walls for a custom layout—perfect for creating a separate storage area.
To explore the full range of options, including roof styles and additional windows for side elevations, Pent Haus’s online configurator provides an effortless way to design your dream space.
Nationwide Delivery and Support
With over 15 years of expertise, Pent Haus crafts their garden rooms in mid-Wales using CNC machinery for precision. Kits include floor, wall, and roof structures, along with low-maintenance cladding, double-glazed uPVC windows and doors, and an EPDM roof covering. Optional extras, such as foundation systems, interior finishes, and electrical packs, can be added during the design process.
Delivery is available nationwide within three weeks of ordering. Comprehensive assembly manuals, instructional videos, and a support team are available to ensure a smooth installation process.
Durable, Low-Maintenance Construction
Pent Haus garden rooms are built for year-round use and require minimal upkeep. The specialist foundation system combines recycled plastic posts and stainless steel framing, ensuring durability and easy levelling. Exterior walls feature ToughWood™ cladding, available in six colours or customised shades, for a contemporary, long-lasting finish.
The insulated roof structure uses a one-piece EPDM membrane, offering leak-free performance and a long lifespan. Plastisol-coated roof kerbs and double-glazed uPVC windows enhance the building’s comfort and efficiency throughout the year.
Customisable Interior Finishes
Pent Haus offers flexible interior options, including vertical tongue & groove panelling for a classic look or a plasterboard finish ready for plastering. All panels are pre-cut with concealed joints for a clean, polished appearance. The SIP panels also allow for concealed electrics, with sockets sitting flush to the walls.
For those adding the electrical package, a qualified electrician will be needed to connect the garden room to your home and issue a Part P certificate.
