RIBA Chartered Practice

Thorns Ha-Ha | 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.

Thorns Ha-Ha | New Forest, Hampshire

New Build Private House

Client: Private  

Type: Residential

This project is for a new contemporary dwelling located on the coast in the New Forest, Hampshire. The site is subject to drastically differing land levels, as such the proposed design takes inspiration from this as part of what informs the development of the architecture.

The building straddles two different land levels, the first an elevated position for countryside views, and the second a lowered pasture for grazing. The site has an existing Ha-Ha, which is a man-made wall that divides a field between its functions. The design of the house therefore deals with this change in site level whilst complimenting the flow of the landscape.

Snapped flint bound into masonry walls is selected as the material for each book-end wall of the two main forms of the building.  Timber and white painted brick are the infill materials for walls and cladding, whilst zinc panels create a sharp edge to the roofing. The materials are carefully selected to relate to the countryside surroundings and draw influences from materials found on or nearby the site and the further surrounding vernacular architecture. However, the design is inherently contemporary and the application of these materials help to create an architectural language that is befitting of the site and surrounding area, maintaining a rural countryside feel whilst being a considered contemporary piece of modern architecture.

Inside the house, the lower portion features an open plan living and kitchen space complete with decking and storage rooms.  Above this sits a study and loft area. The upper portion of the house has three bedrooms and a colonnade passage, framing views to the tree lined boundary of the countryside site.
