REDUCED TO £650,000 Freehold | EPC Rating: A | 5 Bedrooms | 3 Bathrooms CERTIFIED PASSIVHAUS HOME — READY TO MOVE IN Llwyn Onn, Trefin, Pembrokeshire National Park Move in today. Energy bills measured in tens, not hundreds. One of fewer than 5,000 certified Passivhaus homes in the UK — set in the heart of the Pembrokeshire National Park. ABOUT THIS HOME There are homes that look beautiful. There are homes that feel special. Very rarely, a home comes along that does both — and then costs almost nothing to run. Set within the Trefin Conservation Area in the heart of the Pembrokeshire National Park, this is one of just three individually designed and independently certified Passivhaus homes — a building standard so exacting that fewer than 5,000 such properties exist across the entire United Kingdom. This is not a home that simply claims to be energy efficient. It has been engineered and certified to the world's most rigorous performance standard, with heating costs estimated at under £100 per year. In a world of rising energy costs, that is not a footnote — that is the reason to buy. WHAT IS A PASSIVHAUS? From the outside, it looks like a beautifully designed contemporary home. On the inside, it operates on an entirely different level. Triple-glazed windows eliminate draughts and external noise. A continuous mechanical ventilation system circulates and filters the air, maintaining a consistent, healthy internal temperature year-round — without relying on conventional heating. The building envelope is so precisely constructed that the structure itself does the work. The result: Comfortable — constant internal temperature, year-round. Healthy — internal air is continuously circulated and filtered. Quiet — triple-glazed windows minimise all external noise. Economic — approximately 90% lower energy costs than a conventional build. THE ACCOMMODATION This completed, ready-to-occupy residence is arranged over three levels and designed to maximise light, countryside views, and the exceptional quality of the Pembrokeshire surroundings. Entrance Hall A bright and spacious entrance that sets the tone for the home's contemporary layout. Clean lines and considered finishes connect the ground floor living areas to both the first floor above and the flexible lower ground floor below. Kitchen / Dining / Sitting Room At the heart of the home — a stunning open-plan space occupying the full main floor. Full-height south-facing glazing floods the interior with natural light and passive solar warmth, while sliding doors open directly to the landscaped garden. A glass-fronted balcony terrace extends the living space further into the landscape, ideal for al fresco dining and evening relaxation. The kitchen is sleek, handleless and fully integrated with contemporary appliances, designed to function as beautifully as it looks. Cloakroom Conveniently positioned off the entrance hall with contemporary WC and basin. Store Room Useful additional storage at ground floor level. First Floor — Bedroom 1 with En-Suite The principal bedroom is generously proportioned with sweeping rural views. The en-suite shower room is finished to a high specification with walk-in shower, vanity unit, low-level WC, and fully tiled walls and floor. Bedroom 2 & Bedroom 3 Two further generous double bedrooms, each with outlook over the Pembrokeshire landscape and served by the beautifully appointed family bathroom featuring a freestanding bath, walk-in shower, low-level WC, vanity unit, and premium contemporary fittings. Lower Ground Floor — Bedrooms 4 & 5 / Flexible Accommodation The lower ground floor unlocks the home's full versatility. Two spacious rooms — each with direct access to the rear garden via sliding doors — can serve as Bedrooms 4 and 5, or be configured as a home office, studio, gym, or self-contained annexe. This level is served by its own en-suite shower room and a second cloakroom. Plant Room / Utility Housing the advanced mechanical systems of the Passivhaus — MVHR ventilation unit, utility connections, and laundry provision. Smart, discreet, and fully specified. OUTSIDE Beautifully landscaped gardens with south-facing terracing and patio areas. Solar panels contribute to the property's outstanding energy credentials. Parking for up to three vehicles. The development comprises just three individual homes, each with its own garden and aspect. THE LOCATION Trefin is one of North Pembrokeshire's most cherished coastal villages — a Conservation Area settlement within the National Park, minutes from the Pembrokeshire Coast Path and the beaches at Abereiddy, Abermawr and Pwll Deri. The village pub, community hall and local café serve the community well. The cathedral city of St Davids and the market town of Fishguard are within easy reach for schools, amenities, and transport connections.
