“We wanted a bright building, ...an understated atmosphere, ...a modern look and feel to demonstrate that we are aligned with clients. Your design achieved all of these objectives”

“Open plan is not common among law firms. At your suggestion we tested it, decided to use it and 6 years later we are still delighted with the results”

Kevin Hoy - Testimonial

Mason Hayes & Curran website


The project was part of a campus of buildings on the client’s lands, the office building for the practice is the first phase of a planned larger development.

The office building encompasses the gable of the adjoining protected warehouse via a glazed link. An atrium allows all working areas to benefit from natural light and reinforces the open plan arrangement adopted by this leading legal practice.

The east- and west-facing façades of the building are fully glazed to exploit city views yet use passive technologies, including external brise soleil, to reduce solar gain and glare.

The site required an extensive flood protection strategy. Windows, doors and entrances at street level feature steel flood doors finished in natural stone cladding designed to compress into a steel frame with the compression of the flood waters
