Larch Posts 100 x 100 Flat Top – Durable, Stylish, and Timeless

When it comes to outdoor construction, the quality of your materials determines not only how your project looks today but also how it will stand the test of time. Our Larch Posts 100 x 100 Flat Top are crafted from premium European larch, one of the most durable and attractive timbers available for garden use. These robust posts combine natural strength, striking beauty, and versatile design, making them the perfect foundation for fences, gates, pergolas, and a wide variety of garden features.

The Natural Benefits of Larch

Larch has long been valued in landscaping and construction thanks to its unique qualities. Unlike other softwoods, it is slow-grown in harsh climates, developing a dense structure and high resin content that give it exceptional durability. These natural characteristics make larch highly resistant to rot, decay, and the unpredictable weather conditions of the British Isles. Unlike pressure-treated timbers that rely on chemicals for longevity, larch provides resilience through its very nature.

Freshly cut larch is instantly recognisable by its warm straw-to-light-brown colour and attractive grain patterns. Installed in the garden, these golden hues blend seamlessly with greenery, creating a natural and elegant look. Over time, untreated larch develops a sought-after silvery-grey patina, adding even more charm and character to your outdoor space. Whether you prefer to let it weather naturally or protect its golden tones with a quality exterior oil, larch always delivers timeless appeal.

Why Choose Flat Top Larch Posts?

The flat top design is a classic and versatile choice for garden architecture. It offers a simple, modern profile that works beautifully with both contemporary and traditional landscaping styles. Flat tops provide a clean, uniform appearance that is particularly effective in structured layouts, straight fencing runs, and neatly defined boundaries.

Our 100 x 100mm posts are cut with precision, ensuring consistent sizing and perfectly squared edges for easy installation. The flat top makes alignment straightforward, allowing you to achieve a level, professional finish across your fencing or garden structure. This design also offers greater flexibility, pairing effortlessly with closeboard panels, slatted fencing, decorative gates, or bespoke timber features.

Outstanding Durability and Strength

At 100 x 100mm, these larch posts provide exceptional stability and structural strength. Their robust profile makes them suitable for heavy-duty applications such as driveway gates, tall fencing panels, and large pergolas. Unlike thinner posts that may warp or split under pressure, larch posts are naturally resistant to twisting and movement, giving you long-term peace of mind.

Key benefits of larch posts include:

• High natural durability – naturally resistant to rot and decay without chemical treatment.

• Weather resistance – capable of withstanding rain, frost, and sunlight year after year.

• Minimal maintenance – can be left to weather or protected with a simple oil treatment.

• Sustainability – larch is an environmentally responsible choice due to its longevity and low treatment requirements.

With proper installation, these posts can last for decades, offering both value for money and reduced environmental impact compared to shorter-lived alternatives.

Versatile Applications

Our Larch Posts 100 x 100 Flat Top are ideal for a wide range of outdoor construction projects:

• Fencing: Strong enough to support heavy timber panels or decorative slatted fencing, creating secure and stylish garden boundaries.

• Gates: Suitable for both pedestrian and driveway entrances, these posts provide reliable support and a refined finish.

• Pergolas & Arbours: The perfect uprights for shaded seating areas, walkways, or climbing plants.

• Garden Features: Use as supports for trellises, screens, or bespoke timber creations, adding both practicality and visual appeal.

Whether acting as the main load-bearing structure or as finishing elements, larch posts bring strength, character, and design consistency to your garden architecture.

Natural Beauty, Supplied Untreated

We supply our larch posts untreated, allowing you to decide how best to finish them. Left in their natural state, they will gracefully weather to a silver-grey that works beautifully in contemporary landscaping. If you prefer to retain the golden tones of fresh larch, applying a quality exterior oil or stain will both protect the wood and enhance its natural grain.
