You get a top-quality garden cabin with a low carbon footprint made from ethically sourced materials. The clean and straightforward design makes it easy to assemble, and all the fixtures and fittings required are included as part of your order.

            Please note: Images may show accessories and furnishings for display purposes only and are not included with your purchase. 

            Does A Log Cabin Require Planning Permission?

            The garden building designs have been created to adhere to planning permission guidelines. However, we cannot guarantee that you will not need planning permission for a log cabin.  We advise checking with your local authorities before constructing your garden room.

            What Log Cabin Base Do I Need?

            A flat, level base is required to install your log cabin. You can contact us for more information on building a garden room base.

            Before installation, check that the base is level in all directions. If the floor is not level, it will cause the building to twist and warp with the natural movement of the timber. It’s essential to adjust your base accordingly to achieve this before the installation process begins.

            Log Cabin Aftercare

            The Mercia Log Cabin with a side shed is supplied untreated. To ensure you enjoy your garden cabin for many seasons, you must apply a preservative and waterproofing topcoat immediately after installation. These treatments, followed by yearly log cabin treatment, will maintain the high-quality finish and retain the 10-year anti-rot guarantee. A 1-year manufacturer's warranty is included as standard.

            To treat the garden room, elbec recommends Protek wood treatment. Browse our Protek Royal Exterior Wood Finish Paint range to find the best paint colour to add your personalised finish.  We have selected some of the best-selling Protek Royal Colours as an option on this page and the highly recommended Protek Wood Preserver++.

            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 7 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.


            Please note: all imperial measurements are approximate, and the Mercia Log Cabins are made from metric measurements. We would recommend that the base is at least 50mm bigger in each direction.
