Brief Your Architect — How a €5,000–€10,000 Brief Saves You €50,000 in Rework
On this page
When this matters most

When this doesn't apply
You've already lodged planning drawings. You're moving into technical design (Stage 5 onwards).
Frequently asked questions
How much does an architect cost for a self build in Ireland?
8–12% of build cost for full RIAI service. €15,000–€35,000 for a €300k–€500k build. Reduced fees for partial service (planning only, for example) of 3–5%.
What is RIAI?
Royal Institute of the Architects of Ireland. RIAI contracts (standard 2012 agreement) define scope, fee stages, and responsibilities. Always use the RIAI contract.
When should I appoint an architect?
Before you lodge planning permission. Sometimes immediately after site purchase, especially if the site is complex. Stage-specific recruiters: environmental consultant, BER assessor, quantity surveyor — these come after.
Can I be my own assigned certifier?
No. The assigned certifier must be a registered professional (architect, engineer, or building surveyor on the BCAR register).
What's the difference between an architect and an architectural technologist?
Architects have an RIAI-recognised qualification and can take BCAR roles. Architectural technologists (CIAT) handle the same design work but cannot sign off on some BCAR roles. Both can prepare planning drawings.
How long does planning design take?
6–10 weeks from kickoff to planning lodgement for a one-off house. Add 4 weeks for design changes after planning feedback.
