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.

Paul Cashin Architects Achieves Planning for New Project

We are delighted to announce that our contemporary house extension in Sidlesham, West Sussex, has received planning permission.

The project will involve the refurbishment and extension of a detached cottage in a conservation area, at the southern limit of Sidlesham Quay village.  The property was highlighted by the local authority as a key example of rural vernacular character for homes in the area.  Paul Cashin Architects were appointed in December 2015 to remodel the house for new owners, with work starting in the Spring of 2017.  The design includes a landscaping strategy that alleviates flood risk by providing a bung to the garden edge, whilst encouraging native species planting to take over a new timber structure that is directly connected to the house.  This approach will help to plant the house in its surroundings, which is vital given the local connection to the Sidlesham Nature Reserve.

Take a closer look at the scheme on our projects page here, or if you would like to discuss a project please view our contact page here. Our office is located in Winchester, Hampshire, but we undertake projects across the whole of Southern England.
