The main objective of this project was to create a sustainable, low-energy family home that maximised its coastal views. Other key requirements included wheelchair accessibility, four en-suite bedrooms, and adaptable spaces for both the family and guests. 

This project combines innovative design, sustainability, and seamless functionality. It adheres to Passivhaus principles, resulting in exceptional energy efficiency. Through a combination of high-performance triple-glazed windows, insulated fabric, strategic orientation, and an efficient MVHR system, it achieves a remarkably low operational carbon footprint. Additional standout features include the integration of renewable energy systems, such as a ground source heat pump and a 6 kW solar PV system with battery storage, ensuring minimal environmental impact throughout the home’s lifecycle. 

Despite obstacles during the process, the project was completed to the highest standards, with the final result exceeding expectations in terms of both design and sustainability. Successful collaboration with the client, suppliers, and contractors enabled the team to navigate these challenges and deliver a home that sets a new benchmark for sustainable coastal living. Clear communication with the client ensured their vision for a multigenerational, accessible, and sustainable home was brought to life. The team also incorporated virtual reality technology, allowing the client to explore the design in detail. This immersive approach ensured the layout and features aligned with the client’s expectations before construction began. 

Turnstones delivers a future-proof, energy-efficient home that meets the client’s functional and aesthetic needs while setting a high standard for sustainable coastal living.
