Antony Gibbon's Burl Treehouse takes its name from something genuinely wild. Burls are those gnarled, bulbous growths that push out from tree trunks over decades — resilient, organic, unplanned. Gibbon, an architectural designer known for sculptural forms that sit somewhere between biology and architecture, has channelled that same quality into a spherical forest pod. The result is a dwelling that doesn't impose on the woodland around it. It appears to have grown there.

Each pod sits suspended above the forest floor, balanced on stilts or lightly tethered to nearby trees. The engineering is deliberate in its restraint. From a distance, the exterior reads as almost prehistoric — a hull of charred wooden shingles in the Shou Sugi Ban tradition wraps the whole form, darkening it until it dissolves into the canopy shadows. The contrast between outside and inside is immediate and striking.

Step through the entrance and the interior opens in pale ash or cedar, warm and curved in every direction. A large circular window pulls daylight into the space and casts a soft, shifting glow across the walls. The built-in double bed, integrated shelving and discreet storage fit the curved shell without crowding it. A compact en-suite completes the layout. Nothing feels squeezed; the scale is intimate without ever feeling confined.

One of the more forward-thinking aspects of the design is its modularity. Individual pods can connect to form clusters, joined by bridges or shared terraces. For an eco-resort setting, this opens real possibilities — linked retreats, communal decks, private canopy rooms within a larger off-grid community. The Burl Treehouse thinks beyond the single stay.

The design places the concept firmly in countryside as rich as the Sussex weald, where beech woods shift from green to gold across the seasons. Summer evenings stretch long and warm, ideal for sitting out on any shared terrace. Autumn brings crisp, golden light through the canopy — photogenic and calm. Spring fills the understorey with wildflowers and birdsong, making the forest feel especially alive from a pod perched above it. Even winter has its appeal: cool, quiet and stilled, with occasional frost sharpening the woodland silhouette outside that circular window.

Travellers approaching by train will find Stonegate station the closest rail point, roughly 6.4 km away in East Sussex. Etchingham and Robertsbridge offer alternative train connections at approximately 8.4 km and 8.8 km respectively. The surrounding lanes are rural, so most visitors would need onward transport from any station — a car remains the practical choice for reaching this kind of deep-countryside setting.

The Burl Treehouse is, at present, an architectural concept rather than a bookable address. It circulates widely across sustainable design platforms and has drawn genuine attention from the hospitality industry. For anyone planning an eco-retreat, commissioning a forest stay or simply looking for a new benchmark in what a treehouse can be, it matters. It proposes a way of living in the forest that is lighter, quieter and a little closer to the sky than almost anything built before it.
