PERCHED ABOVE THE BEACH ON THE LLŶN PENINSULA
This private garden in Abersoch was designed to make the most of one of the finest views in North Wales. It also had to survive salt spray, sea winds and near-constant UV exposure. Millboard Enhanced Grain in Golden Oak gave designer John Cavalheiro a surface that matched the quality and aesthetic of the wider scheme while standing up to the demands of the property’s coastal location, and it was specified throughout.
The result is a garden that reads as an extension of the house: calm, tactile and built for daily use, from breakfast in the sun to late evenings around the fire.
THE BRIEF: RELAXED COASTAL LUXURY, BUILT TO LAST
The property sits within an exclusive private development, exposed on its seaward side and framed by expansive glazing. The client wanted a luxurious, sheltered space for outdoor living that never competed with the horizon.
John’s design balances clean architectural structure against soft, natural texture drawn from the surrounding Welsh landscape. Large-format porcelain paving handles the open terraces. Warm-toned decking defines the softer, more social zones and carries the eye down towards the water.
At the heart of the scheme sits a sunken lounge, complete with integrated seating and a central fire feature. Subtle level changes separate each zone without breaking sight lines, so the view across the bay stays uninterrupted from almost every seat.
WHY COASTAL COMPSITE DECKING SUITS AN EXPOSED SHORELINE
A seafront site is one of the hardest tests a deck surface can face. Salt-laden air, wind-driven sand, standing water and heavy summer sun can all shorten the life of traditional timber. Boards can move, splinter, silver and demand annual sanding, staining or oiling.
Millboard boards are wood-free, so there is no timber in the core to absorb moisture, warp, rot or split. Nothing needs to be stained or sealed each spring. For a coastal second home that is well-used in season and left to the weather out of it, that difference is the whole case.
Three practical points made Millboard resin mineral composite decking for coastal gardens the right call here:
- Moisture resilience. With no wood content, the boards are unaffected by damp, rain and sea air, and will not swell or splinter underfoot.
- Grip when wet. The Lastane surface layer holds its slip resistance in wet conditions, which matters on a terrace that runs down towards a beach and a pool.
- Low upkeep. Occasional cleaning replaces the annual maintenance cycle of sanding, staining and sealing, leaving more time to use the garden.
Golden oak: warmth against stone, glass and sea
Aesthetically, the scheme needed contrast. Pale porcelain, glass balustrades and a bright sky can easily read as cold.
Enhanced Grain in Golden Oak answers that. The colour has the honeyed warmth of new oak, and because the boards are hand-moulded from real oak planks and hand-tinted, no two are the same: the grain shifts across the terrace exactly as timber would. Against grey stone and dark furniture it feels natural rather than manufactured, and it shifts beautifully through the day, from bright and sandy at midday to deep amber at sunset.
Generous planters filled with low-maintenance coastal planting soften the hard landscaping, while structured hedging gives privacy and shelter from sea breezes without closing the space in.
A garden that follows the sun, then the fire
The garden now works as the most used room in the house. Seating areas are positioned to track the light. Loungers catch the morning. Deep sofas take the afternoon. A dedicated dining terrace faces the sunset, with an outdoor kitchen alongside for entertaining.
As daylight fades, the character changes completely. Integrated lighting picks out the steps, the planting and the grain of the decking, and the fire pit becomes the focal point. The garden turns into a sophisticated evening retreat, comfortable well into the shoulder seasons.
Underpinning all of it is a material palette chosen for a seafront site. Porcelain, glass and Millboard wood-free resin mineral composite decking hold their appearance through salt air and UV with minimal upkeep – just a periodic wash with soapy water – it requires no sanding, staining, or sealing, so the time goes into using and enjoying the garden rather than maintaining it.
