Mercia 8 x 8 Helios Curved Roof Summerhouse

The Mercia 8 x 8 Helios Summerhouse is a stylish garden building featuring a unique curved roofline that makes it a striking focal point for any outdoor space. Large styrene-glazed windows and French doors allow natural light to flood the interior, creating a bright, airy atmosphere that’s perfect for relaxing, entertaining, or using as a hobby room. Whether you’re looking for an arts and crafts space, a reading retreat, or a cosy summer room, the Helios Summerhouse offers the ideal balance of design and functionality. Built in the UK from sustainably sourced timber, this summerhouse uses 12mm shiplap tongue and groove cladding for a robust, weather-resistant finish. The roof and floor are also manufactured from 12mm tongue and groove boards, ensuring a solid, long-lasting structure. A high-quality mineral felt roof covering provides additional protection against the elements. Secure mortice locking, robust fixtures and fittings, and a high-grade timber construction ensure durability and safety. Backed by a 10-year anti-rot guarantee (when treated annually with a good quality wood preservative and waterproof topcoat), the Helios Summerhouse offers long-term reliability and peace of mind.
