As energy efficiency becomes increasingly important for modern homeowners, Thorntons Quarry offers a rare opportunity to acquire a home that has been designed from the ground up with sustainability at its core.
The property benefits from an advanced Air Source Heat Pump, underfloor heating throughout, Mechanical Ventilation with Heat Recovery (mvhr), superior levels of insulation and high-performance triple glazing.

The Passive House approach ensures minimal heat loss, excellent air quality and a quieter internal environment, delivering tangible benefits for homeowners every single day.
A Home Designed Around Modern Family Life
The design creates a sense of individuality and character rarely found in contemporary developments. Each floor has been thoughtfully arranged to maximise natural light, create distinct living zones and provide flexibility for changing family requirements.
At the heart of the property lies the impressive open-plan kitchen and dining area. This bright and welcoming space has been designed for modern living, whether entertaining guests, enjoying family meals or simply relaxing at the end of a busy day.
Large sliding doors and Juliet balconies allow natural light to flood the room while creating a seamless connection between the interior and outdoor spaces. The elevated position enhances the sense of openness and contributes to the home's impressive architectural character.
Bespoke Kitchen Designed Around You
The kitchen is supplied by the renowned Magnet Kitchens, offering both style and functionality in equal measure.
Unlike many new-build developments, purchasers at Thorntons Quarry have the opportunity to personalise key aspects of the kitchen design. Subject to build stage, buyers can participate in dedicated design consultations to select finishes, worktops, cabinetry styles, handles and layout options.
A comprehensive range of integrated appliances is included, ensuring the kitchen is ready to meet the demands of modern living from day one.
This ability to customise allows purchasers to create a kitchen that truly reflects their own tastes and lifestyle requirements.

Both rooms benefit from excellent natural light and offer flexibility for a variety of furniture layouts.
A contemporary family bathroom serves this floor, featuring stylish fittings and modern finishes carefully selected to complement the overall design aesthetic of the home.
An Exclusive Principal Suite
Occupying the entire second floor, the principal bedroom suite offers a private sanctuary separated from the main living accommodation.
This impressive retreat has been designed to provide privacy, comfort and a sense of exclusivity.
The spacious bedroom is complemented by a beautifully appointed en-suite bathroom, creating a luxurious environment for everyday living.
One of the most distinctive architectural features within the property is the unique glazed element overlooking the living space below. This innovative design detail reinforces the contemporary character of the home while creating a visual connection between the various levels.
The result is a principal suite that feels both private and architecturally impressive.
Outdoor Space Designed for Modern Living

The elevated position enhances both privacy and outlook, contributing further to the property's appeal.
