RIBA Chartered Practice

Paul Cashin Architects | Contemporary Chartered Architects in Winchester, Hampshire / News

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.

Paul Cashin Architects was founded in 2012 by Paul Cashin. Paul studied Architecture at the Universities of Portsmouth and Vienna, graduating in 2011 with an RIBA Presidents Medal nomination. He has worked for numerous practices, including Design Engine Architects working on contemporary university, school, housing and one-off house projects between 2008 and 2012. Paul has also taught at the University of Portsmouth and was a member of the Project Office for the school. Paul started PCA in 2012 which has set up offices in Winchester in 2016.

Paul is an RIBA Chartered Architect registered with the ARB.

Paul Cashin Architects - Summer Internships and New House in Hampshire

Paul Cashin Architects are pleased to have Beth Aston, BA Architecture student from the University of Portsmouth, here with us this summer in an internship capacity.

At university her work focused on the experiential nature of architecture, studied through rigorous experimentation of different physical techniques and processes - from hand drawing to physical modelling and sculpture. She is currently refining ideas for a final dissertation on the relationships between architecture and music.

She has been doing some great work and learning a lot in the process: from physical and computer model making to producing information for pre-app planning meetings and client presentations, as well as learning new CAD software and various practice procedures.

An example of this is a 1:50 scale model of a proposal for a new build replacement dwelling near Winchester, in Hampshire.

The scheme proposes to replace an existing uninhabitable building on site with a new detached contemporary property.

The new building will include 3 bedrooms, master suite, open-plan kitchen, living, diner, separate enclosed living space, utility room, WC and an office space situated on a mezzanine level above. Exposed brick, concrete floors, timber walls and the careful composition of views, roof lights and circulation will help to articulate an interesting and considered interior arrangement to the rooms. An open and flexible feel to the communal living spaces draws comparison to the Swedish idea of the ‘allrum’, or family room, and will contrast with the privacy and seclusion of the bedrooms.

Externally, the architectural concept draws influence from the surrounding site conditions, proportions and local rural vernacular. Two barn-like forms are proposed over a split-level arrangement across the sloping site, in place of the existing house.

The visual impact of the proposal is minimised through the idea of two forms, as opposed to a single, larger mass. The smaller of these is slipped back in plan, making it more subservient compared with the larger, primary form.

The external aesthetics draw influence from Scandinavian styles and the rural architecture of Britain. Natural and black stained timber are proposed, along with composite windows, slate tile roofs with overhanging eaves and dusty grey render-smeared brick walls. Accents of metal articulate details, such as bespoke gutters that project beyond the building facade. These work to turn the pouring rainwater into a feature to be seen and appreciated, rather than ignored.

This consideration of the elements and working mechanics of the architecture is carried through the sustainable aspirations of the project. Solar panels compliment a highly thermal efficient, super insulating timber construction, energy efficient mechanical ventilation, and water harvesting. While the landscape scheme has been drafted with reference to encouraging a coexistence between the human occupants and their wildlife counterparts, by creating an ecosystem of hides, crevices and nooks among wild grasses, dense vegetation and tree shadow.

Overall, the finished scheme will be a considerate, beautiful example of contemporary Hampshire architecture, situated harmoniously within the site and will enable the occupants to enjoy vast and expansive views over the surrounding fields and tumbling Hampshire countryside.

The project is to be submitted for planning over the next few months.
