DLM Architects

- Our Ethos -

DLM Architects is an award winning RIBA chartered practice. We believe that architecture should not just be seen as a statutory requirement, but be viewed as an opportunity to maximise the potential of your investment and the enjoyment of your home. We provide a full service from conceptual design through to completion allowing a more efficient and refined solution to our clients brief. DLM is built on a framework of architecture, product design and construction, working collaboratively with a network of quality consultants, hand-picked to meet the specific needs of each project.

Although a relatively small community, Guernsey is privileged to have a hugely varied landscape supporting a diverse range of lifestyles. The shared ethos of our team is to develop high quality progressive architecture that embraces heritage and challenges convention. Our highly skilled team believe that we have a social responsibility to improve our environment and enhance the landscape of our island. Whilst sustainable technology has become industry standard, we believe good architecture should also identify how a building can adapt with the lives of it occupants and how it can develop from and enhance the surrounding landscape.

Our experience of local planning policy and the Island Development Plan allows us to identify a balanced contrast between significant character and intelligent design, maximising the potential of your project.

We create architectural responses, informed by specific site conditions, the ways in which people utilise and inhabit spaces, and the unique and varied ways in which we each choose to live.

Our bespoke services incorporate concept design, planning and building licence applications, construction detailing, contract administration and project management.
