Middleton Engineering Design is a design-led architectural practice providing a full range of building design, planning and project management services. Middleton Engineering Design provides design services for Domestic housing, Commercial and large small residential developments, throughout the greater Connaught area. These counties include Sligo, Leitrim, Mayo, Galway and Roscommon.

Middleton Engineering Design is actively involved in researching the most energy efficient housing and highly recommends that clients now pursue the construction of a passive house. A passive house is a carbon neutral and only uses heat from appliances to create space heating. The managing director of Middleton Engineering Design, Richard Middleton, has also valuable experience in supervising construction of projects from one-off domestic construction to large scale commercial construction such as the construction of apartment blocks to large scale shopping units.
