"The Sanctuary Treehouse" was designed by HollandGreen for the 2025 RHS Chelsea Flower Show. Visitors got to experience The Sanctuary—a tranquil treehouse retreat designed to embody simplicity, harmony, and natural beauty.
Designed as a response to the modern world’s fast pace, The Sanctuary is more than just a structure; it is an invitation to slow down, breathe, and reconnect with nature – the perfect ‘me-space’. Crafted using sustainably harvested timber, the installation embodies our commitment to the environment.
Marley Timber Shingles were installed on the roof of the treehouse, a truly beautiful natural building material that showcases the warmth of timber.
