Why you should consider a SIP extension for your home

Why You Should Consider a MyEco SIP Extension

If you’re planning to extend your home or garden space, there’s a building method that’s growing in popularity – and we’ve seen the benefits first-hand. SIPs (Structural Insulated Panels) offer a smart, efficient, and eco-conscious way to create additional space with minimal disruption and maximum performance.

At MyEco Garden Room, we’ve successfully delivered SIP extensions for a number of clients – combining modern construction with beautiful, practical design. Whether you’re considering a rear extension, home office, or studio space, here’s why a SIP build might be the perfect fit.

What is a SIP extension?

SIP extensions are built using high-performance panels made from an insulating foam core sandwiched between two structural boards. These panels form the walls, roof, and floor of the structure, creating a strong, airtight, and highly insulated building envelope – assembled quickly and with less on-site disruption than traditional methods.

We’ve used SIPs on several extension projects, and the results speak for themselves: fast builds, high energy performance, and beautifully finished spaces.

Why choose SIPs over traditional building methods?

Conventional extensions often involve lengthy construction timelines, weather-dependent delays, and more on-site mess. SIPs are pre-manufactured to exact specifications, meaning your structure can be up and watertight within days – not weeks.

Here’s why many of our clients opt for a SIP extension:

1. Faster build times
SIP panels are delivered pre-cut and ready to assemble. Once on-site, your extension takes shape quickly – often within just a few days – saving time and minimising disruption.

2. Exceptional thermal performance
SIPs are incredibly well-insulated, helping to regulate indoor temperatures and reduce reliance on heating or cooling. This keeps your space comfortable year-round and helps cut energy bills.

3. Airtight and efficient
Thanks to their sealed structure, SIPs eliminate draughts and moisture ingress. We pair this with appropriate ventilation systems to ensure fresh air circulation and a healthy indoor environment.

4. Slim walls, more room inside
Because of their excellent insulation properties, SIPs can achieve the same performance with less wall thickness – giving you more usable internal space without increasing the building footprint.

5. Environmentally friendly
SIPs are a sustainable choice, producing less waste on-site and contributing to long-term energy efficiency. It’s a great match for eco-conscious homeowners.

6. Customisable design
From compact extensions to larger open-plan living spaces, SIPs offer design flexibility to suit your needs and style.

MyEco’s experience with SIP extensions

While we offer a range of building systems depending on the project – including lightweight steel-based structures – SIPs are a proven option we’ve used for both garden rooms and full home extensions. We’ve completed a number of SIP extension projects for clients looking for quick, efficient builds without compromising on performance or aesthetics.

Our team understands the ins and outs of working with SIPs and can help guide you through everything from initial design to final installation.

Do SIP extensions need planning permission?

Many SIP extensions fall under permitted development rules, especially those under 30 m². However, depending on the size and location of your extension, you may still need planning permission or building regulations approval.

If you're unsure, we’re happy to help. Our team can liaise with your local authority and ensure your project meets the necessary requirements – taking the stress out of the process.
