This 5m x 3m Insulated Garden Room offers a modern and stylish building that is both practical and comfortable. The building is completely modular, meaning that you can position the panels of the building to your specification, moving windows and walls to give you your perfect garden room. The windows of this garden room are double glazed to keep as much warmth inside as possible, with two of the glazed panels including opening top windows. Spotlights have been fitted into the roof overhang to illuminate the front of your garden room at night.

Please Note: The price of this item includes full installation of the building into your garden. You should always check with your local planning authority prior to purchase. A firm and level base is required for this, either made of solid concrete or concrete slabs. It is recommended that the floor of this garden room is further covered by either carpet or laminate to reduce wear on the match boards.

Please Note: These Insulated Garden Rooms are NOT pre-treated or painted. Application of wood preservative is also not part of the home installation service. In order to qualify for our 15 year anti-rot guarantee the building must be annually treated with a high quality spirit based wood preservative.

Delivery Information

Delivery Information

We aim to deliver all products as soon as possible. Please check individual product pages for delivery lead times and services associated with each product in your order (These are stated in the top right hand corner of the product page). Below is an outline of the services we offer on Adley products.

Standard Delivery

We will contact you on the morning of your confirmed delivery date by email and/or SMS with a two 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.

Lead times for standard services are stated at the top of the page and may be extended depending on location and circumstances. Upgraded services may also result in a longer lead time.

Log Cabins & Garden Rooms

Due to the large size of Log Cabins & Garden Rooms deliveries have to be made on larger vehicles. Log Cabins come flat packed and are delivered to the kerbside, driveway or front garden. Our delivery team will contact you via telephone to arrange a suitable delivery date. Don’t worry if you don’t hear from our team immediately, once your log cabin is manufactured and ready for delivery a member of the team will contact you.

Please Note: Deliveries of Log Cabins or large items may incur an additional delivery fee.

Installation Service

Installation is available on many of our products for most UK postcodes and the lead time is normally between 14-21 working days after your order has been delivered. This is to ensure that you have fully inspected the product and are happy to proceed. In busy periods this lead-time may increase.

Pick a Day Delivery

We offer a pick a day delivery service on a wide range of our garden buildings and other products, simply enter your delivery postcode to see all the available delivery dates for your area and choose the one that best suits you. This service is for selected products, and will be highlighted on all qualifying products under the delivery section.

Pick a day delivery is subject to availability. Postcode must match your delivery address, otherwise the delivery date may not be available. Pick a Day delivery is not available when Home installation is selected, you will be contacted by the installations team to arrange delivery and installation dates. Pick a Day delivery on orders placed through finance are also not available and are subject to credit checks, which are outside our control. In such cases you will be contacted to rearrange delivery. Terms & Conditions apply.

Delivery FAQ

Do I need to be home for my Delivery?

No, you do not need to be home for your delivery. All we ask is that you let us know via email or signed note to let us know that you will not be present for the delivery. In the note please let us know where a suitable place would be to leave the building. Our delivery drivers are NOT allowed to place your shed in your back gardens even if the gate is left open.

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.

My house has a restricted access, what do I do?

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 any questions about access or you live in a restricted access zone please contact us prior to ordering.

My Order Has Not Been Delivered, What Should I Do?

We deliver between 7am and 7pm. If your order has not been delivered when expected please click here.

Please Note: Additional items such as the plastic shed bases, security locks and shelving may be delivered separately on a different day to your main product. If you have ordered multiple products in one order then you are likely to receive multiple deliveries.
