As a sole principal, every instruction is handled personally — there are no handoffs to junior staff. You get consistent, experienced professional input from first contact to final sign-off.
The practice covers the full range of pre-construction and compliance services: energy ratings, cost planning, construction inspections, and building surveys — making it straightforward to source multiple services from a single trusted point of contact.
Northern Ireland has its own regulatory framework — Technical Booklet F1, SAP 2009 Conventions v5.0, and separate Building Control processes. Declan works exclusively in NI and understands the local requirements inside out.
