Create a private oasis from the hustle and bustle with comfy furniture so you can relax with a good book.

A summerhouse is also excellent for a summer garden office or the place to do your favourite crafts and other hobbies. Whatever you have in mind, you’ll love every minute you spend in your new summerhouse.

Please note: Images may depict furnishings and accessories; these are for illustration purposes only and are not included with your order.

Summerhouse Aftercare:

The summerhouse has a base coat on both sides; this is a water-based golden brown product for protection during transport. If you choose the unpainted option, you must apply a preservative and waterproofing topcoat immediately after installation. Using the treatment after installation, followed by consistent annual treatment of the summerhouse, will maintain the high-quality finish required for the 10-year anti-rot guarantee. A 1-year manufacturer's warranty is included as standard. All you have to do is assemble and enjoy!

To protect the summerhouse, elbec recommends Protek wood treatment. Browse our Protek Royal Exterior Wood Finish Paint range to find the best summerhouse paint colour to add your own personalise finish.

Factory painting option is available for this summerhouse; your paint colour choice can be applied prior to shipping. With the painting option, this also includes the assembly of your summerhouse. After the first year, a yearly treatment will be required to comply with the 10-year anti-rot guarantee.

Booking Delivery

You will be required to book your delivery date at the time of placing your order (except for Metal Shed). Our 'Request a Delivery Date' service is available to the majority of areas and you'll find that the majority of the UK postcodes are FREE but some areas may incur a delivery surcharge and some postcodes are not covered at all. Select a 'requested delivery date' by entering your postcode in the 'Request a delivery date' section above. You will also be notified at this time if your area incurs a surcharge or delivery is not covered in your area.

Prior to Delivery

On the morning of your delivery date, you'll be sent an update by text with an estimated 2-hour delivery slot (this update can only be provided where a mobile number has been supplied on the billing address section at the time of checkout) together with a link to the manufacturer delivery portal where you'll be able to track your order.

Please note: Mercia Metal Sheds ONLY - your order is delivered by a courier you will not be notified prior to the delivery. If you are not in on the day of the delivery you will be carded and asked to contact the courier to arrange a new mutual delivery date. The estimated delivery lead time for Mercia's Metal sheds is identified on the product for the metal shed. Lead times are on working days (Monday - Friday) excludes Bank Holidays. These estimated lead times are provided by the manufacturer. Some remote areas will take a little longer.

Upon Delivery

Your order is delivered either kerbside or driveway and will be delivered on either a 3.5T, 7.5T or 18T Lorry. Unfortunately due to health and safety and insurance liabilities the driver will not be able to take your goods around to the back of your property but may upon request place the product at the side of the house if there are no access or restriction issues. We would not risk damaging your property whilst delivering a product to an unsafe location. Unfortunately, we will not be able to go through your property.

We would recommend against arranging for a third party to install the building before it's been delivered and checked that all parts are present, as we cannot be held liable for any third-party costs.


Orders with Assembly 

The lead time for our installation option is around 12 weeks from the date of order. With the installation option, the majority of orders will have their delivery and installation on separate days; there will be a small number of orders which will have delivery and installation on the same day. You will be advised by the manufacturer's installation team which category your order falls into.

Depending on the installation option for your order, you will be contacted within the delivery timescale and given a date for either delivery/assembly on the same date or a separate date for delivery and assembly.
