The Team


Our team offer expertise in Building Services Design, M&E Sustainable Design, Lighting Design, BREEAM Assessments, Energy Performance Certificates, Project Management, Value Engineering, Feasibility Studies and Condition Reports.

AH Design has two partners, Sam Abbas and Anthony Hayes, two senior engineers, Danny McConaghie and William Ross, and two CAD Technicians, Ciaran Francis and Reuben Simpson.

Sam Abbas, Anthony Hayes and Danny McConaghie are Chartered Engineers and William Ross is currently in the process of obtaining his Chartership.

Due to the size and structure of our team, each engineer completes their own design and will see a project through from inception to completion thus ensuring a continuity of service.  Our engineers are experienced in using AutoCAD for 2D drawings and Revit MEP Level 2 for 3D drawings in addition to the use of other design software to complete the mechanical and electrical services details for all projects.
