Currently having a number of live projects across Winchester, Hampshire and the South Coast including one-off new build houses, extensions and commercial business projects.


As a small practice, our strength lies in our inclusive and personal approach, working directly with clients, consultants, and contractors, encouraging the cross over between architecture and other areas of art and design.

We are in a consistent state of process, working through a range of media including physical and computer models, hand and computer drawings, sketching and conceptual diagrams, discussions and presentations.

Paul Cashin Architects Collaboration with CHORA

On Wednesday 14th February, Paul Cashin Architects welcomed Roger Tyrrell and a group of University of Portsmouth undergraduate film students to their office in Winchester to develop and capture the process of refining the key construction details for the extension of Roger's own house project.

The aim of the session being to produce clean, robust and well considered details. The process used the in-office chalk wall to explore details at 1 to 1 scale. Through conversation and drawings, the details were refined and various options explored.

The event was in collaboration with Chora (a new company founded by University of Portsmouth Professor and Architect, Roger Terrell).

CHORA is designed to occupy the current void between the creative practice and Academia. Historically considered as distinct and exclusive, CHORA strives to conjoin these territories, as the contemporary globalised context of the creative and knowledge economies demands. If the currency of the future is creative ideas, CHORA seeks to encourage, facilitate, and support, the conjunction of Praxis and Research within a single entity, and, through the innovative processes, encourage rigorous and informed creative pathways that are intelligent and responsive to current and future societorial demands.

Planning for the project was granted at the end of March. The details will be developed further with the aim of starting work this summer.

The project site is located in a cul-de-sac located on the outskirts of Emsworth town, Hampshire. The existing property is a single storey bungalow with two bedrooms. The client wishes to extend the property in order to gain more generous living spaces which relate to the rear garden, and adapt the existing living spaces to become an additional bedroom and ensuite bathroom.

The core concept design principles being; reduced mass and form, lower ridge height, subservient, contrasting, enclosing, space making.

The proposed extension will sympathetically reflect the scale and proportions of the existing property while providing a precisely detailed contemporary addition. This will be enhanced further by a considered landscape proposal providing diverse wildlife habitats.

The design for the new extension will be constructed of white painted brick, and bituminous corrugated cladding. The pitched roof will also be finished with the same recycled bituminous corrugated cladding giving a sense of wrapping. Deep reveals will provide shade to the more exposed elevations and give depth to the elevation.

The client has a keen interest in wildlife and the natural environment. The landscape proposal draws upon their travels around the world.

As such, the landscape has been an integral aspect of the design development for the proposal, with planting/landscaping designed to enhance and make a dynamic inside outside space that responds to both building and the natural environment.
