Our Builds


Each of our garden room projects is supported by individually prepared plans and designs assisted by the latest CAD/CAM technology. Following a full site survey, consultation and approved quotation we provide working drawings and a detailed specification. These are of the standard you would expect for an architect designed bespoke house build.


Whilst we employ a range of technology in our Norwich factory, we are proud to say that every garden room component remains hand crafted and finished by our skilled tradespeople. Sustainability and a blend of traditional and modern methods support our unique build system, designed specifically for garden rooms. The walls feature a hard wearing textured wall covering to the interior, fully washable and available in a choice of colours. Similarly we offer a selection of exterior traditional and contemporary finishes, which are all selected for their sustainability.


All windows and doors are PVC-U framed for reduced heat transmission & strength, featuring 28mm thermally efficient glass as standard. Floors and ceilings are both insulated, with the floor finish included from a range of carpet or vinyl based laminate. Lighting is included as recessed, energy efficient low voltage LED down-lights and each garden room comes complete with an electrical socket package and mains distribution board.

Our Business

We're actually one in a family of three 'Image' companies. These include, Image Development, Image Display & Graphics and of course Image Garden Rooms. We believe each of our collective brands make us unique and much better at what we do across the entire Image family. 

First opening in 1989, we incorporated in 1996 and remain a proudly family owned, Norfolk based business. We have more than 30 years of experience working with timber structures and buildings, working in all manner of indoor and outdoor environments. In addition to garden buildings, we have award winning design and build expertise that we've applied to exhibition stands, event environments, commercial receptions, showrooms and more, picking up some nifty tricks, techniques and technologies along the way. 

With our unique experience, we understand exactly what it takes to deliver complex projects, with no margin for error. At Image Garden Rooms we remain committed to the highest levels of service and quality placing our clients at the heart of all we do. Quite simply we pledge to“do what we say we will do, when we say we will do it”.
