A landmark in contemporary Welsh architecture, Cwm Mawr is an extraordinary coastal residence set in over 18 acres of private grounds above Pen-y-Cwm beach, commanding cinematic views over St Brides Bay and the surrounding Pembrokeshire Coast National Park
Designed by acclaimed architect Tom Kinver and awarded Wales Home of the Year 2020/21, this iconic four-bedroom property combines curvilinear design, a living roof, and light-filled interiors with a rare degree of privacy and position. From the moment you arrive via the sweeping driveway, it is clear this is a home of substance, style and complete seclusion.
Inside, the atmosphere is one of calm luxury, with elegant bathrooms, an understated high-spec kitchen-dining room and carefully curated natural materials throughout. Every detail has been considered - from ultra-fast internet for modern living to immersive connection between house, land and sea.
Outside, landscaped wildlife-friendly gardens, stunning ponds and secluded entertaining terraces and decks, most of which have magnificent coastal views. The front terrace is a delightful secluded space with pizza oven and verdant gardens. The beach and Pembrokeshire Coast Path are moments away, with Newgale, Solva and Haverfordwest within easy reach.
Despite its remarkable sense of seclusion, Cwm Mawr is far from remote. The charming coastal villages of Newgale and Solva are close by, offering a warm community atmosphere, while the market town of Haverfordwest—only eight miles away—provides a full range of shops, restaurants, and amenities. Locally, you’ll find other Pembrokeshire gems such as Whitesands Bay, Ceibwr Bay, and Mwnt—perfect for dolphin-spotting, watersports, or simply soaking up the region’s unspoilt coastal charm.
All of this lies within the protected beauty of the Pembrokeshire Coast National Park, where every day begins with the sound of the sea and ends with a horizon painted by spectacular sunsets. Whether as a permanent residence, a luxurious holiday retreat, or an income-generating coastal escape, Cwm Mawr offers a truly rare opportunity to own a slice of Welsh paradise.
