We believe that a buildings fabric should be carefully considered in the design & planning phase of a building as it plays a leading role in the energy efficiency of a structure. The design & specification of a building fabric is a major determining factor of energy use in any building. It has to strike a balance between ventilation & daylight requirements & the need to provide a comfortable environment for the users.

From the very beginning we help our clients navigate the complexities of alternative choices regarding sustainability, ensuring value and lower running costs without compromising on architectural integrity. At Hillen Architects each project is assessed on an individual basis to determine the most appropriate sustainable strategies. Passive strategies are first considered before suggesting technological solutions.

"Slievemoyle cottages have used the services of Hillen Architects for several building projects over a period of years and have been extremely happy with the outcomes. Barry has been receptive to our ideas and brought these together with his professional expertise to produce plans which meet our needs. The buildings produced have been practical, functional, aesthetically attractive and yet not expensive to build."

"We used Barry to design and oversee the build of our house in Newcastle. He overcame problematics planning issues, and had an excellent relationship with our builder than culminated in the completion of our property on time. Barry had a professional and imaginative approach to the build, which helped us through the design and build process."

"Barry's efficiency in obtaining our Planning Permission within a short timescale and with no objections or amendments required is further testimony to his excellent attention to detail and his expertise and professionalism. His willingness to assist and co-operate with Building Control officials and the Building Contractor involved in the building of our home removed a lot of potential pressure for us and provided us with full confidence that our project was managed to the highest of standards."
