The Harlow Insulated Garden Room

Looking to create a contemporary home extension that offers something unique? Perhaps you require additional living space, a home office or a garden gym. The Harlow Insulated Garden Room provides an all-purpose space, designed specifically for year round use.

From our premium Sherwood range of insulated garden rooms, our flagship range is named from our local roots; Rufford, Thoresby, Creswell, Harlow and Edwinstowe. 

This 4m x 3m garden room boasts an architecturally stunning exterior, with clean angles and a geometric shape. Our unique wing design creates an ultra-modern and stylish aesthetic, guaranteed to become a feature within your garden. The wings create a sheltered porch to the front of the building, perfect for rainy days or for added shelter in the summer. Manufactured to order here in the UK by our highly skilled team, using only the highest quality materials, you can be confident in the quality.

So much more than a summerhouse, this building is packed with premium features as standard. The walls, roof and floor contains Eco-quilt multi-foil insulation, which provides the same insulation as 100mm of glass wool. This combined with the double glazed windows and French doors ensures a warm, welcoming and comfortable interior all year round. The 100mm double skinned walls have also been designed with an easily removable internal panel to enable you to fit and conceal any electrics you may require – perfect for tidying away all your office cables. Finally the roof is covered with a superior waterproof rubber membrane, designed to last for 50 years!

Available in multiple variants, this garden room is versatile and customisable. Looking for more windows? Not a problem. Wanting to move the door location? We can do that. Just give us a call and we can discuss the options with you!

Important Information

Where can I find the exact measurements of my Insulated Garden Room?

Before purchasing your new Insulated Garden Room be sure to check the specific measurements of its size in the Specification section of the product listing. As often in product titles, we round up measurements just so it’s easier for you to find your perfect garden building.

How will my new Insulated Garden Room arrive?

Garden Rooms are installed by our professional team. These garden buildings are supplied untreated and therefore once constructed you will need to apply a preservative and treatment as soon as possible in order to uphold your 10 Year Anti-rot Guarantee.

Please note that this Insulated Garden Room has been dressed to look its very best in our product images. Any accessories and fixtures featured are not supplied with this garden building.


Does my new Insulated Garden Room come with any guarantees?

As standard, this Insulated Garden Room includes a 1 year Manufacturer’s guarantee, as well as a 10 Year Anti-rot Guarantee*.

What does my 10 Year Anti-rot Guarantee cover?

Our entire range of Insulated Garden Rooms benefit from our 10 Year Anti-rot Guarantee. This will cover your garden building against fungal decay as long as the conditions of the guarantee have been followed.

These conditions include treating your new garden building with a high-quality timber preservative and waterproof top coat.Treatments of this sort should be applied as soon as your garden building has been constructed, and reapplied annually thereafter. This will enable you to maintain your 10 Year Anti-rot Guarantee and will keep your Insulated Garden Room in tip-top condition!

Please note that our 10 Year Anti-rot Guarantee does not cover your garden building from the movement of timber that takes place over time. This includes; the twisting, warping and splitting of timber.

For more information on our 10 Year Anti-rot Guarantee please refer to our Terms & Conditions.


Does my new Insulated Garden Room require planning permission?

We work hard to design all of our garden buildings to adhere to the planning permission guidelines. However, we cannot guarantee that planning permission will not be required. Therefore, before constructing your garden building we advise checking with your local authorities.


What base do I require for my new Insulated Garden Room?

A flat, level base is essential for the installation of your Insulated Garden Building. We recommend the following bases; concrete, or a wooden frame.

Prior to the installation of your Insulated Garden Building be sure to check your base is level in both directions. If the base of your Insulated Garden Room is not level when it is constructed it will cause the building to twist and warp with the natural movement of the timber. Therefore, it is really important to adjust your base accordingly to achieve this before the installation process begins.

For more information on how to build a suitable base take a look at our handy guide.

How do I care for my new Insulated Garden Room?

To ensure your Insulated Garden Room stands the test of time it’s important to follow the guidance outlined in your building’s product instructions and Manufacturer’s Recommendations.

We have also created these super handy Maintenance Guides to help you take care of your garden building. They are full of our expert advice and useful tips so you can enjoy your Insulated Garden Room for years to come!

However, if you need any further support, don't worry we are on hand to help. Just give our friendly Customer Service Team a call on 0800 029 1000.

Frequently Asked Questions

Can I choose a delivery slot?

We will contact you on the morning of your confirmed delivery date by email and/or SMS with a 2-hour delivery time slot. We aim to meet these delivery times but during busy periods, deliveries may take a little longer, however we always work hard to keep delays to a minimum.

What access is needed for my delivery?

Our drivers are only contracted to provide kerbside drop offs and deliveries. They will NOT bring any of our orders through your home. A driver may offer to take an order further; for instance a back garden but this is ONLY at their own discretion. If you have added our installation service to your order please be aware that they will require full access to your garden. Our installation team will not bring a building through your home as they are not covered by insurance to enter a customer's home. If you have any questions about access or you live in a restricted access zone please contact our sales team on 0800 029 1000. Our team will be able to provide you with more information and specific building information.

Will I need to help my delivery driver?

Our drivers DO NOT need your help during a delivery. They will not ask for your help and they can manage all the items themselves. We are not insured to cover any customer injuries and therefore we ask you NOT to help or try and help our drivers while they make a delivery.
