3 bed barn conversion for sale

Hartfield Road, Cowden TN8

A rare opportunity to purchase a bespoke net-zero luxury home with zero energy bills.

Set within a private gated development just minutes from Cowden station, this exceptional 3-bedroom end-of-terrace luxury energy efficient home delivers an extraordinary blend of contemporary architecture, dramatic volume and true net-zero living. A development of just nine homes built by award-winning developer Q New Homes and meeting the standards of the riba Climate Challenge, the home achieves industry-leading sustainability with running costs reduced to zero at normal usage.

Vaulted curved ceilings, a striking double-height entrance and expansive architectural glazing create a light-filled interior with a sense of scale rarely found in modern homes. The beautifully crafted open-plan kitchen, dining and living space forms the centrepiece, complete with a bio-ethanol eco-fireplace.

The principal bedroom features a luxurious ensuite and dressing room with two further generous ensuite bedrooms. A utility room and secondary living spaces offer everyday practicality.

Sustainability is at the forefront: Air source heat pump, mvhr, a powerful solar array, super-insulated SIPs structure, low-carbon materials, charred-larch cladding and jet black zinc roofing. These innovations deliver net-zero operation, outstanding air quality and incredibly zero energy bills, making the home both future-proof and economical.

Homes at Hartdene Barns feature no mdf anywhere, replacing traditional skirting with elegant shadow gaps and natural stone window and door sills, creating a crisp, contemporary finish while also reducing exposure to VOCs and formaldehyde typically associated with mdf products.

Each property includes its own flourishing organic allotment, complete with a bespoke potting shed crafted from reclaimed cladding off-cuts, encouraging self-sufficiency, outdoor living and biodiversity.

Just a 3-minute drive or a scenic 12-minute woodland walk to Cowden station, the home offers fast London connections while being embraced by the tranquility of the High Weald. Nearby attractions include Hever Castle, Chiddingstone and miles of beautiful hiking and cycling routes.
