and progressive

Globally recognised pioneers in environmental design and construction, we combine creative architectural solutions with you and the future in mind, delivering sustainable and desirable features in every project.  

Working towards a defining design, through experience and careful research, we can offer unique perspectives and ideas for your project,  which always combine innovative building and construction techniques with finesse.

Buildings, spaces, and homes don’t just happen. It takes well integrated collaboration between both the local community and imaginative professionals to realise and visualise a defining design.

Committed to minimising each of our projects’ impact on the environment, we evaluate and optimise three areas of focus in every new project: the intended use of the building, architectural design and the construction process. But no two solutions are the same, they are tailor-made for your specific development, the site and location.

Architecture should always encapture the spirit of the surroundings without succumbing to mainstream trends. We pride ourselves on forward-thinking stylish and timeless designs that are bespoke to your requirements and will withstand the test of time.

Artistry and innovation


From its formation in 1988, Bree Day’s approach to urban design and master planning follows the principles of eco-urbanism, which aims to achieve harmonious and balanced-built environments by using existing natural systems and characteristics to inform design solutions.

Founders and directors Tim Day and Damian Bree strive to continually improve the architecture and technical performance of the projects they are involved in while seeking urban design solutions to help minimise the impact of new developments on the environment.

Tim Day B.Arch

Tim is a founding director at Bree Day. He’s a registered architect and qualified urban designer with a 30-year tenure working on a portfolio of building types across the UK and overseas, and takes care of all design and planning at the office.

Tim has always had a keen interest in improving the environmental performance of architecture and urbanism through the application of passive design principles, which, today, lies at the core of his designs.

Damian Bree

Damian Bree co-founded Bree Day alongside Tim after qualifying in Architectural Technology at Bolton Street, Dublin, and moving to London where he worked at several practices. He also has experience of working in the Middle East.

Damian has a particular interest in the practicalities of building and how technology can support environmental designs as architecture evolves. He has spent much of his career investigating renewable technologies and sustainability for environmental construction.

Press And Public Speaking

In addition to membership of professional bodies, Bree Day is a member of, and have supported, INTEGER Intelligent and Green, the UK Green Building Council, UK Urban Design Group, Town and Country Planning Association, Associate Parliamentary Group for Design and Innovation, and Local Urban Task Force.

Bree Day participates in a global network of multi-disciplinary organisations committed to improving the sustainable performance of built environment projects, and has also been featured in the media, notably:

BBC Radio 4 Live radio interview with Damian on Housing and our Integer
House at the BRE.

At the invitation of the UK government’s British Expertise, Tim gave a paper at the Green Building Council seminar in Philadelphia, Pennsylvania, US

SKY NEWS studio appearance to discuss new UK Eco village.

Gave a presentation on 'Green Buildings - a UK Perspective'​ to the American Institute of Architects (AIA) in New York at the invitation of UK Trade and Invest.

The University of Exeter. Gave a presentation on 'Applying Best Practice Energy Technologies in New Developments'​ to the Devon Sustainable Building Initiative.

At the invitation of UK Trade & Invest, Damian travelled to Turkey as part of their UK-Turkey Urban Regeneration Symposium, speaking in both Ankara and Istanbul on 'Sustainable and Environmental Ecological Developments'.

Through UK Trade and Invest, an exhibition prototype model for sustainable ways of designing and building caught the eye of the BBC, and this was subsequently built over a 13-week construction programme in the summer of 1998 and broadcast on BBC1 the following year. The house still stands at the entrance to the BRE.

Bree Day was a pioneering partner of Integer Intelligent and Green, a forum that started with support from the BRE in investigating renewable technologies along with sustainable ways of designing and building. Integer quickly found itself as the focal point of environmental construction, with interest and support from central government, developers and manufacturers.

Through Bree Day’s Integer initiative, the architects have a close collaborative working tie with Oval Partnership, a Hong Kong architectural practice now undertaking work under the Integer Asia banner.
