Measuring Ø300cm across and built from 28mm-thick kiln-dried spruce logs, it combines classic craftsmanship with a versatile, airy design.

Make the Most of Your Summerhouse

The Helensburgh’s light-filled interior makes it ideal for various uses. Furnish it as a stylish garden lounge for entertaining guests, a reading and relaxation space, or even a home office with views in every direction. The tall opening windows allow for excellent ventilation, keeping the interior fresh and comfortable throughout the warmer months.

Its spacious octagonal design also makes it perfect for year-round enjoyment. Add comfortable seating, soft lighting, and perhaps a small dining set, and you have a versatile retreat that works just as well for summer evenings as it does for crisp winter afternoons. However you style it, the Helensburgh offers elegance, practicality, and lasting appeal.

Key Features & Build Quality:

Prima System Wall Construction

The Prima system is a patented, innovative 3-in-1 corner construction method that sets this summerhouse apart. Crafted with precision, it unites timber elements with concealed aluminium profiles inside the corner posts, delivering a flawless fit and a sleek, contemporary look.

Unlike traditional cabins with bulky extended log corners, the Prima system creates perfectly smooth, streamlined edges. This gives the log cabin a strikingly modern appearance while maintaining exceptional strength and stability.

Another key advantage is that the Prima system requires no nails or screws. With no visible fixings, the wood remains intact, extending its lifespan. Assembly is quick and straightforward, leaving you with a timeless structure that will enrich your garden for years to come.

Laminated Doors & Windows

Unlike many log cabins and summerhouses, Lugarde features laminated doors and windows, made with 45mm thick laminated wood. Laminated timber is commonly used in high-spec construction because it combines the natural beauty of wood with modern engineering for superior strength and durability. The layered construction makes it far less prone to warping than solid wood. By bonding multiple layers together, laminated timber achieves greater stability and longevity. Through the use of premium engineered wood and MDF, Lugarde ensures its doors and windows remain durable, stable, and resistant to distortion over time.

Concealed Hinges

Both windows and doors are fitted with concealed, neatly covered hinges that create a clean, polished appearance. Each door is equipped with three hinges for added strength. The hinges are fully adjustable in all directions, ensuring smooth operation and allowing for easy fine-tuning of the door’s alignment over time.

Aluinium Door Strip

The door's threshold comes with a protective aluminium strip, complete with pre-drilled holes, designed to shield the door sill from everyday wear and keep it looking like new.

Weather Strips for Windows and Doors

All windows and doors are supplied with weather strips to keep out drafts and moisture. For added protection, the internal frames' edges come with a removable foil covering, ensuring a spotless finish once painting is complete.

Optional Upgrades & Customisation:

EPDM Rubber Roof

Enhance the durability and weather resistance of your Lugarde summerhouse with our high-quality EPDM roofing solutions. The summerhouse comes without a roof covering, allowing you to either select our EPDM Rubber Roof option or purchase your own roofing felt from a local supplier. Designed to provide superior protection, EPDM is a versatile and long-lasting material that ensures your timber structures remain secure against the elements. Its strong waterproof properties, combined with resistance to UV rays and temperature fluctuations, make it an ideal choice for outdoor use.

Plastic Floor Beams

Although a timber foundation kit is included, you can choose to upgrade your structure’s foundation with plastic composite floor beams—a smart, durable alternative to timber. Designed to resist warping, rot, and moisture damage, these beams offer long-term strength without the upkeep associated with wood. They won’t attract pests, don’t require staining or treatment, and remain stable in all weathers. Lightweight yet sturdy, this composite beam also make installation faster and simpler. Plastic is a practical and proven choice for a reliable, maintenance-free base that stands the test of time.

Installation & Preparation:

Summerhouse Base

We recommend that the summerhouse is sited on pre-laid, level, solid and dry ground. A foundation of hardcore, compacted, and concrete or paving slabs to give a stable and even footing for your garden room to sit on. You can request 'Guidelines for Preparing a Concrete Base' through our 'Contact Us' Section. This summerhouse is supplied with comprehensive fitting instructions and fixings provided. Two people are required to complete the build.

Gorilla Ground Screws

Gorilla Ground Screws provide a fast, clean, and hassle-free alternative to traditional foundations. Available in lengths of 1050mm and 1200mm, they eliminate the need for digging and concrete, reducing mess, disruption, and costs. Interested in a quote? Get in touch with us today.

Summerhouse Aftercare

The Lugarde Summerhouse 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 summerhouse treatment, will maintain the high-quality finish and retain the 5-year warranty. A 1-year manufacturer's warranty is included as standard.

To treat the wooden summerhouse, 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. 

Does A Summerhouse Require Planning Permission?

This is advisory information which may vary.  We cannot guarantee that you will not need planning permission for a summerhouse. We advise checking with your local authorities before constructing your garden room. 

If your summerhouse is close to the fence or boundary (within 2 metres), it can be no taller than 2.5 metres at the highest point.

If it’s set further back (more than 2 metres from the boundary):
• With an apex (pointed) roof, it can be up to 4 metres high.
• With a flat or single-slope roof, it can be up to 3 metres high.
