RIBA Chartered Practice

Timmer House | Private House

Paul Cashin Architects 'PCA' is a creative RIBA (Royal Institute of British Architects) Chartered Architecture practice based in Winchester, Hampshire. PCA takes a design-led approach to the practise of contemporary architecture, believing that well thought and considered design is essential to the creation of successful architectural space.

The practice undertakes contemporary architectural design projects across residential, commercial and civic sectors of the construction industry. 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.

Timmer House | Portland, Oregon, USA

New Build One-off House

Client: Private  

Type: Residential

This building project, whose client is a mountain guide in the Pacific North West, builds upon the traditional vernacular architectural forms and rhetoric of the US prairie house. Starting with an open veranda on all sides, a common room is focused around a hearth, lit from above via a glazed chimney stack, and contained in a heavily constructed brickwork form. Two bedrooms with ensuite spaces sit on the opposite side with views across the meadow. Although the compositional articulation of these spaces draws its roots from surrounding architectural styles and influences, the overall design is inherently contemporary.

The site is a lease hold field, with a windswept westerly aspect against the forest edge. Therefore the house is sited leeward of a planted orchard, which acts as a wind break, whilst referencing the grid of the timber farmed veranda.
