Structural Design

We have experience in the design of structural elements for houses, commercial buildings,  industrial buildings, including pharmaceutical buildings and workshops, warehouses, and schools.


Construction Supervision

We are able to monitor/supervie the construction of all the projects we design. We also regularly monitor the construction of projects where planning permission has already been obtained.

What we do.


We are involved in many emerging house technologies using different materials to maximise the thermal efficiencies and comfort levels in houses, including a number of passive houses.

Commercial Buildings

We have been involved in a number of commercial buildings from refurbishments to large commercial units/apartment blocks, generally working as part of a design team.


We have experience in designing warehouse structures, including large steel portal frames, concrete floors, including insulated cold-room floors, and piled foundations.


We have been involved in the design process for some schools, again working as part of a design team.

Industrial Buildings

We provided the civil and structural design for the Enterprise Centre at the Ecovillage in Cloughjordan, Co. Tipperary, which involved applying sustainable principles to a larger scale building.
