Certus Garden Rooms
Looking to create more space without the disruption or cost of a traditional home extension? The Certus range of modular garden rooms offer a fast, flexible and beautifully finished solution. Whether you need a home office, studio, gym, or simply an extra living area, every Tiger Modular garden room is built with high-performance insulation, durable materials and professional-grade fixtures – all as standard.
The Certus Range – Spacious, Smart, and Stress-Free Part of our accessible and highly adaptable Certus range, these modular garden buildings are available in nine size options and are ideal if you want maximum space without unnecessary add-ons that inflate the price. Each Certus garden room includes everything you need for comfortable year-round use – insulation, heating, electrics, high-spec doors, flooring and internal finish – included as standard, not as extras.
The result is a complete room solution that’s competitively priced, easy to install, and ready for whatever you have in mind – from remote working to relaxation.
Built to Last. Designed for Life. Tiger Modular garden rooms are constructed from precision-engineered SIP panels, pre-fabricated in our Yorkshire workshop to reduce on-site mess and ensure a flawless finish. Each room is clad in Thermowood® for natural durability and style, with Cedar options available if you prefer a premium timber finish.
The models in the Certus range come with a choice of secure, aluminium-framed doors – either Bifold or a fixed-pane Double Door – and full double glazing for warmth, light, and peace of mind.
Quick Installation, Minimal Disruption Unlike traditional brick builds, Tiger Modular’s prefabricated garden rooms are expertly installed by our in-house team in under a week – from foundations to final fix. The majority of the construction happens off-site, so you’ll enjoy a quicker turnaround, less stress, and no construction debris left behind (we handle the site clearance too).
Designed for Space. Built for Comfort. Whether you’re expanding your living space, creating a peaceful garden retreat or building a productive home office, the Tiger Modular Certus range delivers extra square footage without the cost and complexity of bricks-and-mortar construction.
