Threshold Architects: Award-winning bespoke design and Passivhaus specialists in South Devon.
Threshold are award winning RIBA chartered architects and Passivhaus designers based on the edge of Dartmoor in South Devon. We provide bespoke residential design across South Devon and the South Hams, creating high-performance homes that put sustainability at their heart.
Our passion for making places that feel special and relate comfortably to their settings is combined with a commitment to put sustainability at the heart of all our projects. By integrating Passivhaus and EnerPHit principles, we create homes that offer the luxury of a perfect climate, exceptional air quality, and a home that treads lightly on the earth without compromising on design.
Our skilled and creative team has extensive experience navigating Devon’s complex planning landscape, particularly within AONBs and sensitive heritage sites. Whether you are envisioning a coastal new-build or a contemporary barn conversion, we provide a bespoke and personal service that balances ambitious architectural vision with the technical rigour required to ensure your investment is both viable and enduring.
Project Highlights
Featured Project
Little Lutterburn
South Hams Barn Conversion
As architects in the South Hams, we are often involved in reimagining traditional barns and previously converted buildings. This contemporary addition transforms the layout of an existing compact dwelling, creating a vaulted ply lined entrance with a feature staircase, broken plan reception spaces and a new master suite at first floor.
Clad in zinc and cedar, this new element has open gables drawing light deep into the plan. On the edge of a conservation area in the South Hams the project connects the house to its garden and creates a light and relaxed home.

Architects in Devon
Threshold provides a comprehensive, design-led service that bridges the gap between visionary architecture and technical performance. We specialise in low-energy contemporary homes, including Passivhaus and EnerPHit retrofits, for clients who value a holistic approach. From initial feasibility and energy modelling to interior and landscape integration, we manage every detail of the construction process, ensuring your project is as meticulously executed as it is designed.
Our portfolio is defined by a deep understanding of Devon’s most sensitive environments. We are experts in navigating the distinct requirements of Dartmoor National Park, the South Hams National Landscape (AONB), and coastal conservation areas. Whether it is a contemporary barn conversion, a bespoke coastal new-build, or the sensitive restoration of a listed building, we balance ambitious architectural goals with the rigour required for success in protected settings.
Based on the edge of Dartmoor, we serve clients across South Devon and the South West. Our work is concentrated in the coastal and countryside hubs of South Devon, including Salcombe, Dartmouth, and Newton Ferrers, as well as the vibrant communities of Totnes, Kingsbridge, and Exeter. From the rural landscapes of Tavistock, Modbury and Ivybridge to the architectural opportunities within Plymouth, we bring a local’s insight to every site we touch.
