Your dream summer might include time spent relaxing or entertaining in your own stylish garden room. Hugely popular in the UK right now, a modular garden room brings outside spaces to life and delivers the valuable, usable additional space that modern families increasingly crave.
Why choose a modular garden room?
Modular garden rooms are fast and easy to erect, ideal for a small, skilled DIY team. Our galvanised steel frames are precision-designed to fit perfectly and are typically upright in around an hour.
In contrast, brick-built structures require complex planning, a professional build to meet UK regulations and a larger budget for both materials and labour than either timber or modular steel. A modular building will require some ground preparation and stable pad to sit on, but a bricks and mortar building will also need footings, planning permission, building controls and more, adding to the cost.
In terms of longevity, a steel framed modular garden room beats a timber frame every time, resisting rot and pests. While a brick-built structure will stand for decades, it may still require high levels of maintenance and cost more over time to light and heat. The latest in modular steel framework allows for the installation of modern, high-performance insulation, skylights and other technologies designed to maximise energy efficiency and visual impact.

The possibilities are endless
Fast and within a reasonable budget, a modular garden room project could transform your space, offering endless possibilities:
- Home bar or party room
- Personal gym or yoga studio
- Crafts or hobby workshop
- Zen garden retreat
- Teen bedroom or guest annexe
- Spa area with hot tub
- Work-at-home office
If you’d love more space without the hassle of a major building site, a modular garden room could provide the answer. Use a single off the shelf frame or customise your space by joining them together – it is a fast and easy approach.

Frequently asked questions about modular garden rooms
Do I need planning permission for a garden room in the UK?
- A modular building doesn’t always require planning permission, but it is always wise to check with your local planning department. Guidance and building requirements can vary from region to region and in conservation areas.
How much does a garden room cost?
- A modular garden room may cost more than a timber structure and significantly less than a permanent brick built building or home extension. Our range of standard frames have off-the-shelf prices and can be finished with modern materials to minimise running and maintenance costs over the lifespan. Finishing costs will vary according to your tastes and requirements.
Can you live in a garden room in the UK?
- It is possible to live in a garden room in the UK, but this is governed by planning permission and building regulations. Structures must conform to living standards and taxes will be payable.
Can your modular garden rooms be plumbed?
- PermaRoom steel framed buildings have been developed to be fully plumbed, wired for electrics and insulated to a high standard.
