Make the most of your outdoor space with a fully-insulated SIPs Panel Garden Room, Garden Office or even a Garden Gym.

Building a garden room using SIPs panels means low running costs and you will enjoy your new space at all times of the year.

Our panels are pre-cut, pre-insulated and ready for quick and simple installation

Due to the unique way that structural insulated panels work, they’re perfectly suited for garden room constructions that allow you to make the most of your outdoor space – regardless of the weather!

While the majority of our SIPs property builds are commercially focused, there is an undeniable, and growing trend of people extending the size and function of their internal space at home – whether you’re looking for a home office, exercise room or just somewhere to sit and enjoy in your spare time.

All of our SIP garden room kits are designed and fabricated off site to specification at our factory in Scotland.  They’re delivered pre-cut, pre-insulated and ready for install.

Why choose a SIPs Garden Room?

A Structurally Insulated Panels (SIPs) system is one of the strongest construction methods that you can introduce domestically; making SIPs the best choice for garden extensions and garden rooms.

Unlike timber frame designs, log cabins and shed panel constructions; SIPs garden rooms provide a superior level of insulation, which in turn significantly reduces the cost of heating during the winter months – as well as increasing the heat retention overnight in cooler months.

But aside from the cost, convenience and environmental benefits of SIPs as a construction method, they conform to the most recent building standards set by Part 6 of the Building Regulations which now focus on consumption of utilities and power in relation to building performance.

Building regulations, over time, are only going to become more stringent and efficiency-led, and with this in mind, SIPs Eco Panels will eventually become a standard benchmark for future years.

Our high-strength, high-performance SIP panels are:

  • Non-toxic
  • Low carbon footprint
  • Made with 100% recyclable EPS
  • Energy Efficient
  • Fire rated
  • Breathable
  • Mould resistant
  • Extremely Strong

What can a SIPs Garden Room be used for?

SIPs garden rooms are multifunctional spaces that can fulfil a multitude of needs. Whether you’re a busy professional, or looking forward to retirement, a bespoke-built garden room could enhance the features, comfort and value of your home.

Entering retirement

Garden rooms can help you find a tranquil treat away from the main house, that enables you to develop as a keen gardener, or entertain friends without having to tidy, prepare and open up your home.

Growing family

Whether it’s the need for a playroom in the day time and a dedicated study in the evening, an overflow storage room, or a night time hang-out for your teenage children to entertain their friends, a SIPs garden room can be the ideal solution for your growing family.

Busy professional

Although an increasing number of people in the UK are working from home, the truth is that unfortunately, the typical family home wasn’t built with a home office, or dedicated space for this purpose in mind.

Adding a garden room to your home setup gives a busy work-from-home professional the key separation they need between work and home, for that all-important performance-enhancing mental divide.

Why choose SIPs Eco Panels Ltd for your garden room?

As a family-run business with over 35 years’ experience in construction, we have a team of highly-experienced professionals who are on-hand to guide homeowners through every stage of their SIP panel extensions.

When you contact us for a quote, you can upload your drawings (if you have them), and discuss the details of how you want your bespoke garden room. Our team can also install your SIP garden room quickly and efficiently on the day.
