Plots One and Two – Bespoke Passivhaus Homes in Trefin, Pembrokeshire

Set in the heart of picturesque Trefin, these two exceptional new-build Passivhaus homes form part of an exclusive development of three architecturally designed properties. Designed to combine cutting-edge eco credentials with breathtaking views of rolling countryside and the nearby coastline, they offer a rare opportunity to create a home tailored to your own style.

Each property is being crafted to the highest standards of energy efficiency, comfort, and contemporary design. Buyers of Plots One and Two have the unique chance to customise their home—choosing the kitchen, bathroom suites, and final finishes to suit their taste and lifestyle.

Inside, the homes have been designed around a spacious, light-filled open-plan layout, with expansive triple-glazed windows to maximise natural light and frame the views. The main living space flows seamlessly to a glass-fronted balcony and landscaped garden, creating the perfect setting for entertaining or relaxing.

Plots 1 & 2 can be set up as 3, 4, or 5-bedroom properties, with the lower floor offering flexibility to be arranged as a separate annex living area—complete with lounge, bedroom, bathroom, and utility space.

Located within the Pembrokeshire Coast National Park and Trefin Conservation Area, these homes blend modern sustainability with a rich natural and cultural setting. Designed for exceptional energy performance, they feature solar panels, triple glazing, fibre broadband, and an A-rated EPC—ensuring both comfort and efficiency all year round.

Kitchen Options

The kitchens can be fully tailored to your preference, with a choice of layouts, cabinetry styles, worktops, and high-quality appliances. Whether you envision a sleek, minimalist finish or a warm, classic look, the design can be shaped around how you love to cook, dine, and gather with family and friends.

Bathroom Choices

Bathrooms offer the same level of personalisation, with options for elegant walk-in showers, statement freestanding baths, and a wide selection of tiles, fittings, and finishes. From calming spa-like tones to bold contemporary designs, you can create spaces that perfectly reflect your style and daily rituals.

Upstairs, generously proportioned bedrooms enjoy sweeping rural vistas, while outside, solar panels and smart ventilation systems contribute to outstanding Passivhaus performance—delivering year-round comfort and impressively low running costs. The homes feature an MVHR system providing excellent air quality, complemented by efficient electric space heating.

Tucked away in a quiet Pembrokeshire village yet just minutes from the coast path and beautiful beaches, this development offers an unrivalled combination of forward-thinking design and natural beauty.

Plots One and Two provide the rare chance not just to buy, but to help create, your perfect home in one of West Wales’ most scenic locations.
