iHus has built a strong reputation over the past 20 years as a specialist in the design and construction of quality garden annexes. Unlike companies that offer garden rooms and general outbuildings, iHus focuses exclusively on creating self-contained annexes designed for year-round living. Their annexes provide a comfortable and practical solution for multi-generational living, offering independence while keeping families close.
A Range of Self-Contained Living Annexes
iHus offers a collection of pre-designed annexes that can be tailored to meet individual requirements. Their annexes are designed to comply with the two approval routes. The 3632 range is designed to be compliant with the BS 3632 standard under the Caravan Act. With their Classic range, iHus takes a dual approach to gaining approval for your project - the Caravan Act and full planning permission and full Building Regulations standards.
Alongside the 3632 and Classic annexe ranges, iHus also offers the PentHus range, which consists of stylish contemporary one or two-bedroom homes featuring a mix of high-end finishes.
The three ranges allow customers to choose the best option for their circumstances, whether you need an annexe built under the Caravan Act or one requiring full planning and Building Control approval.
iHus living annexes come in a variety of sizes, from more compact models measuring 5.05m x 7.05m to larger designs extending up to 6.5m x 17.05m. iHus also offers a bespoke service, ensuring that each annexe is tailored to suit the needs of the homeowner and their available garden space.
Construction and Build Quality
iHus annexes are built with a focus on durability, energy efficiency, and high-quality materials:
- Foundations: iHus annexes are typically built on screw pile or concrete pad foundations, depending on ground conditions. A swift plinth system is used for mobile homes built under the Caravan Act.
- Insulated Structural Timber Frame: iHus annexes feature a super-insulated structural timber frame, ensuring high levels of thermal efficiency. Marley Cedral Lap weatherboard is the standard cladding, available in a choice of colours, while untreated green oak cladding is also an option for a more natural finish.
- Roofing Options: Flat EPDM roofing comes as standard, but annexes can be upgraded to a warm pitched roof finished with concrete tiles. Vaulted ceilings are available in the main living/dining areas for a more spacious feel.
- Internal Walls: Interiors are finished with plasterboard, skimmed, and painted in the customer’s choice of colour. Shower room walls are finished with tileboard, with the option to upgrade to a wet room.
- Windows & Doors: White PVCu windows and doors are fitted as standard, with 28mm double glazing achieving an ‘A’ energy rating. Premium colour options are available.
- Energy Efficiency: iHus annexes exceed industry standards in energy performance, with walls performing 40% better, roofs 25% more efficient, and floors 30% more effective than annexe models.
Tailored Layouts and Customisation Options
While iHus provides a range of pre-designed annexe models, they also offer extensive personalisation options. From adjusting the internal layout to selecting finishes, customers can work with the design team to create a space that perfectly suits their lifestyle. As shown in these layout examples, iHus ensures that each design is optimised for comfort, practicality, and individual needs.
Traditional and Contemporary Designs
iHus caters to a wide range of aesthetic preferences, offering both traditionally styled and contemporary designs. Customers can choose between dual-pitched and mono-pitched rooflines to complement their garden setting. The PentHus range, in particular, offers a sleek modern design with high-end finishes, making it an attractive choice for those seeking a contemporary annexe.
Viewing an iHus Annexe and the Design Process
A standout feature of iHus’ service is their OpenHus network, where potential buyers can visit real customer annexes to see how they function in everyday life. With over 100 ambassadors across the UK, this network provides invaluable insight into how an iHus annexe can enhance quality of life.
The buying process with iHus is structured to be as smooth and stress-free as possible:
- Understanding Your Needs – The process begins with a video consultation to discuss design ideas, followed by a detailed site survey.
- Planning Permission – For their Classic range, iHus follows a dual approach, applying for both Full Householder Planning Permission and a Caravan Act Certificate, ensuring the best chance of approval.
- Build & Delivery – A dedicated project management team oversees the construction process, ensuring a high-quality finish and timely delivery.
- Moving In & Aftercare – On move-in day, the team provides support, including an optional handyman service, and follows up with a six-month aftercare visit.
A Turnkey Service Across England and Wales
iHus provides a full turnkey service, handling every aspect of the project from design and planning to construction and final installation. Their annexes are delivered move-in ready, complete with kitchens, bathrooms, and utility connections, allowing for a seamless transition into the new space.
