The 11 x 7 Mercia Corner Summerhouse with Side Shed is smartly designed to give you a useful combination of leisure and storage. Included is a large, bright room for you to relax alongside an additional storage space to keep any garden items. Both of these spaces are united in one structure that fits snugly into 90-degree corners. This makes the summerhouse ideal for many gardens, and a multi-functional purchase that will help organise your outdoor area while providing a fun spot to relax.

Ways to Enjoy your Corner Summerhouse

Anyone who loves to make the most of the outdoors will find that the 11 x 7 Mercia Corner Summerhouse with Side Shed gives them a fantastic place to spend their off-hours enjoying the vibrant surroundings of their garden. A picturesque dining setting for several people, there are few better ways to settle down for dinner than while watching the world go by from the comfort of this summerhouse.

The summerhouse can become an airy and open space if you throw open the double doors in warmer months, or a safe retreat to escape a chilly evening in cooler seasons while still being able to enjoy the outdoors through the transparent styrene glazing. And with this combined garden building, you still have the fantastic advantages that come with an integrated shed; this allows you to hide away garden clutter, tools and garden furniture. At elbec, we're certain you will enjoy this superb purchase if you are looking for a building that neatly combines a practical and recreational space into one space-saving package.


The Mercia Corner Summerhouse (with Side Shed) includes a number of features to make it an excellent choice for your garden. The building is constructed using a high-quality 12mm tongue and groove cladding, supported by heavy duty 54mm x 28mm timber framing. Not only does this cladding provide an attractive finish that shows off the sustainable sourced, FSC certified timber; it also ensures that you have a durable and sturdy summerhouse that is well protected from the elements. This timber is used throughout the walls, roof, and floor of the summerhouse to ensure optimal water resistance and so that the floor is able to take heavy loads.

The windows and doors are glazed with styrene, an environmentally friendly alternative to glass that is shatterproof and therefore incredibly safe for use in family gardens. Full-length double door glazing and two full-length side windows combine to give you panoramic views of your garden as well as letting in buckets of natural light. The double doors are secure and lockable (key included), providing plenty of security when leaving items inside. Meanwhile, the wide double doors of the side shed can be locked with the addition of your own padlock due to the inclusion of a galvanised steel padbolt.

Our customers often like to add their own personal touch by painting their summerhouses, which look great in many of the shades created by Protek, available to order from elbec. By using Protek Royal Exterior, you can make the Corner look exactly how you like while adding extra protection to the timber. Although this summerhouse comes dip-treated to provide an initial level of protection from rot and damage during transit and assembly, using a wood preservative like Protek is a great way to keep your 10-year manufacturer's anti-rot guarantee valid and making your summerhouse last. Whether you love to make a bold impression or keep the characterful look of timber's natural grain, Protek has a colour and finish to suit any taste

Additional Details about Your Order

We're pleased to offer the option of booking our dedicated professionals who will assembly your summerhouse quickly and correctly. If you choose to put the summerhouse together by yourself, you will be pleased to find that all fixtures and parts have been included with the delivery. We recommend enlisting the help of one or two friends to help complete this spacious garden building, and you can expect the summerhouse to take up to several days to build depending on your prior experience with similar projects.

This Mercia summerhouse is supplied dip-treated for protection during transit and assembly, but you must apply a wood treatment to the exterior in accordance with any care instructions. Many manufacturers recommend the high-quality products of Protek, available from elbec in over 60 colours. Your timber treatment will need to be repeated periodically (mostly likely on an annual basis) in line with the manufacturer's instructions to ensure your 10-year anti-rot guarantee remains valid.

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.
