High-Performance SIPs Construction for Your Garden Building

Your garden building is constructed using Structural Insulated Panels (SIPs)—a cutting-edge building technology known for its strength, durability, and superior energy efficiency. SIP construction creates a highly insulated, airtight structure that delivers excellent thermal performance, helping to keep warmth in during winter and heat out during summer.

Thanks to the high thermal values of SIPs, your garden room, garden office, or outdoor studio will not require any additional insulation. This ensures year-round comfort while reducing energy costs and improving sustainability.

How Long Should a Garden Room Last?

Long-Lasting and Sustainable SIPs Garden Buildings

Garden buildings constructed with Structural Insulated Panels (SIPs) are exceptionally strong, durable, and sustainable, offering long-term performance with minimal environmental impact. SIPs construction promotes energy efficiency and provides a robust, weather-resistant structure built to last.

With proper care and regular maintenance, your SIPs garden room, garden office, or outdoor studio can deliver a lifespan of 40 to 50 years or more. Like any high-quality building, ongoing upkeep ensures it continues to perform well and remain a valuable, functional space for decades.

Do I need planning permission to put a garden building in my garden?

When considering the construction of domestic outbuildings, planning permission is typically not required, as long as the structure is used for a domestic purpose related to your home.

There are however specific scenarios where you may need planning permission. If any of the following conditions apply, it’s important to check with your local planning authority for confirmation:

If you plan to build the shed within 5 metres of any part of your house.
If the total ground area covered by buildings or other structures in the garden (excluding the original house) exceeds 50% of the total garden area.
If the original planning consent for your property includes a condition that prohibits garden sheds, outhouses, or similar structures, regardless of consent from the local planning authority.
If your property is a listed building or located within a conservation area or an area of outstanding natural beauty, where development restrictions may apply.
If you intend to use the garden building for business purposes or to store goods related to a business.
Additionally, no part of the garden building should be placed closer to the public highway than your existing house, or closer than 20 metres from the highway, whichever is nearer.

To ensure you comply with all regulations, it’s always best to consult with your local planning authority before proceeding with construction.

Do I need any other building consent?

If your property is a listed building or located in a conservation area, it is highly likely that you will need the relevant listed building consent or conservation area consent before proceeding with any construction.

Additionally, some properties may be subject to restrictive covenants, which could prevent you from building in your garden. To determine if such restrictions apply to your property, you should check the property register at HM Land Registry for any entries related to this type of development. If a restrictive covenant exists, you will need to seek consent from the party benefiting from the covenant.

It’s also important to be aware that the current planning permission for your property may include conditions that override permitted development rights. These conditions can sometimes apply to entire areas, so it’s crucial to consult with your local planning authority to confirm whether any restrictions are in place.

If you’re uncertain about whether you can erect a garden building without needing planning permission, it’s advisable to err on the side of caution and contact your local planning authority directly. In most cases, you should receive a response right away.

Please note, we accept no liability for the accuracy of the information provided in this notice. We always recommend seeking professional advice to ensure compliance with all regulations.
