Eco Home Architects

Paul McAlister Architects have designed many Eco Homes throughout Northern Ireland and the Republic of Ireland. An Eco house uses the same principles as Passive House and is built in such a way that it reduces energy consumption and CO2 emissions to the environment. An Eco house creates a healthier indoor environment for the occupants and has a less negative impact on the environment.

Sustainable Architects in Practice

Paul McAlister Architects have been practising for over 15 years; forging a reputation at the forefront of sustainable design as Sustainable Architects and Eco Home Architects.  The Practice’s primary focus is on the delivery of high quality, environmentally responsible architecture, merging sophisticated design and sustainable solutions that respond to our client’s unique needs and their environment.  We give Economic, Social and Environmental Sustainability the precedence it deserves; prioritising ultra-low energy design supported by the integration of sustainable technologies in each and every project we deliver.  We believe that sustainable buildings come from close collaboration between dedicated professionals and enthusiastic clients.

Certified Passive House Architects in Ireland

We are Northern Ireland's first Certified Passive House Designers, which is the world-leading energy efficiency standard and a benchmark of our sustainable credentials. This expertise means we can create environmentally sustainable architecture projects that have exceptional energy efficiency performance.

We recognise the importance of sustainable standards such as BREEAM, Passivhaus and NZEB as a benchmark of buildings environmental performance and the production of eco-home buildings. As Certified Passive House Designers we promote the ‘Fabric first’ reduction of CO2, as a priority and requirement of our sustainable credentials. We understand that CO2 production loses during the lifetime of a building is a major environmental factor.
Along with the CO2 reduction, the building materials specified, their ecological credentials, and the embodied energy of their production and manufacture, needs to be balanced with the long terms economic sustainability of projects.

We design to the BREEAM and Code for Sustainable Homes and will incorporate these additional sustainable standards into our designs; with the aim of minimising the impact that our schemes have on the environment; both in their construction and operation. Ultra-low energy design can become the catalyst for innovative architecture.
