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.

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.

Pybus House | Brighton + Hove, East Sussex

New Build One-off House

Client: Private  

Type: Residential


Paul Cashin Architects has won a private competition to design a new build house in Brighton, Sussex.

The house concept is a new contemporary dwelling, nestled between two existing houses, overlooking the English Channel in Brighton.  The brief asks for alterations to the existing house and then to design a modern new build property, sited alongside.

We believe that the natural response is to work with the exposed saline environment, thin and narrow site proportion, roof height limitation and proximity to neighbouring properties, as well as the relationship with the existing house.  Our proposal therefore takes into account these constraints and focuses on the internal arrangement of living and sleeping spaces and creating a procession of views in accordance with the morning and evening sun path, whilst referencing the atmosphere of beach huts and rustic coastal materials.

The property will feature sub level parking and outdoor equipment storage, three sleeping spaces, and landscaped gardens connecting the house with the sea and sky.
