With its stylish but practical design, the Mercia 4m x 4m Corner Log Cabin (28mm) - Double Glazed is a fantastic garden room in which to switch off, relax and enjoy some well-earned me time.

Walls, Floor and Roof

This large garden cabin is constructed in the UK from 28mm interlocking log boards on a robust 27mm x 44mm frame, so is strong, long lasting, and very well insulated. All of the timber used is FSC®-certified, so only sourced from sustainable, well-managed forests.

The floor and roof are both built from heavy-duty 16mm tongue and groove. The latter comes with an eye-catching apex design and high-quality mineral felt cover for complete weatherproof protection.

Doors and Windows

Easy access is gained via partially-glazed double doors, which are fitted with a sturdy handle and key-operated lock to keep valuable items safe. Two large windows ensure the interior benefits from an abundance of natural light. They are both openers, allowing the cabin to be ventilated, whenever required. Real double glazing is included as standard for enhanced insulation and sound proofing.

Assembly and Maintenance

This corner summerhouse/ log cabin is straightforward to assemble and should be installed on a firm, level base. A competitively-priced professional installation service is available to buy as an optional extra.

As this log cabin is delivered untreated, it must be coated in a high-quality wood preservative and waterproofing treatment upon assembly, and annually thereafter, in order to protect the wood, prevent water ingress, and validate the 10-year anti-rot guarantee. Paint can be applied for a more individual style.

Availability and Delivery

This log cabin for sale is available with 28mm, 34mm or 44mm cladding, and in various sizes.

Delivery is free to most UK addresses.

Measuring 1800mm x 1200mm, a log cabin bar is the ideal addition to a Mercia log cabin. Made in the UK, from FSC®-certified 19mm tongue & groove, it comes with an L-shaped design, spacious bar top and 10-year anti-rot guarantee.

Mercia has a team of trained installers who can carry out your log cabin installation for a professional, hassle-free assembly. Their dedicated training to installing Mercia Log Cabins ensures an expert finish.


Please be aware that the delivery and installation will not occur on the same day but will be scheduled very close together where possible.


The fitters will require at least 60cm/24” on each side of the base to carry out the installation. The base should be level and on firm ground. Mercia recommend that the base be very slightly smaller than the external measurement of the building to create a run off for water and that the door be at least 25mm above ground level to prevent flooding.


Mercia do not provide a service for the preparation of the base area or for installation of electrics, wi-fi, solar lighting or plastic bases. If you require assistance with these, we recommend the use of for locating a reputable tradesperson in your area. Solar lighting packs are designed to be easy DIY assembly.


Please inform customer service BEFORE you order, if you believe there are restrictions which could impact the delivery and installation of the garden room.
