Koha Architects were appointed to design and deliver a high-end residential renovation and extension on a prestigious site in Cornwall, offering sweeping views over the Helford River and Port Navas. The project involved the transformation of a substantial two-storey home that had suffered from a series of unsympathetic additions over the years. Our architectural services included a complete reconfiguration of the internal layout, with a focus on improving circulation, spatial flow, and natural light. A key design goal was to create an *open-plan living environment* that maximised panoramic views of the surrounding Cornish landscape and brought the dramatic riverside setting into everyday living spaces. The works included a thoughtfully designed extension, modernisation of the existing structure, and integration of high-quality finishes tailored to the lifestyle of the homeowners. The result was a seamless blend of contemporary architecture and sensitive renovation, enhancing both the function and aesthetic of the original property. Construction was completed in early 2017. The clients expressed their deep appreciation for the transformation: “We are full of gratitude for Koha’s input into our project. The skill in visualising living space comes alive for us lay folk when the building starts taking form”, Home Owners. This project stands as a leading example of bespoke residential architecture in Cornwall, combining visionary design with deep respect for place and landscape.
