Case study: Tornagrain by Ben Pentreath Architects
Designed in a traditional style by Ben Pentreath Architects, Tornagrain is an emerging new town located to the east of Inverness. As well as delivering 5,000 new homes in response to increased housing demand in The Highlands, the development will provide extensive community infrastructure including schools, shops, health, leisure and employment facilities, with an expected completion date of 2070. Developer Moray Estates aims to create a model town for the 21st century that fosters a vibrant and successful community. So far, several hundred homes have been completed, with further phases under way. Source:Ben Pentreath Architect's voice Achieving a high-quality bar is complicated on any new housing development, but is especially so when the scheme is as ambitious as the new town of Tornagrain. The brief to succeed is fundamentally set by our client, Moray Estates, which takes a long and patient view on its development goals. We have been given time and space to consider local precedents of plans and building types and have an ongoing engagement. The project has had significant financial challenges. Housing values are relatively low, so the margin to create something special and still generate some land value is tight. It has led to some value-engineering. I feel this has improved the scheme, as it is simpler, and that is creating a restrained beauty of its own.

It was the cutest place you could imagine. The houses are so beautiful. I bought my first home here in 2022 – a two-bedroom semi. It has been a wonderful home. I’ve recently purchased a four-bedroom detached house in the village and will be moving in very soon. The village is a real community. There are green open spaces, community gardens and orchards, and lovely paths that wind though the village. We also have our own community association, website and newsletter. Best of all, we have our own village shop, pharmacy and a fabulous café. Soon we will be getting a primary school, doctor’s surgery and more shops. I would not live anywhere else now. Suzi Source:Matti Kremer Client's voice Moray Estate’s vision is the creation of a traditional market town, very like the market towns so enduring and popular all over Scotland. We intend Tornagrain to be a thriving, complex, resilient community, where residents can live, work and find the services that they need in their daily lives. We have come to understand that these things don’t happen by chance, rather that they are the consequence of how a community is planned, what amenities are provided and how that is stitched together in the town plan. We appreciate the benefits of compact, walkable streets designed for people and not, primarily, the car. We would like to see a place develop where the social and health benefits of a community, in the widest sense, are allowed to flourish. John Douglas Stuart, Earl of Moray and landowner
