Architect Quotes in Ireland
Compare up to 4 local architect professionals. Free, no obligation quotes.
An architect does far more than draw plans. They design spaces that work for how you live, navigate planning and building regulations, manage the construction process, and ensure the finished result matches your vision and budget. For any project beyond a very basic renovation, an architect's involvement is the single biggest factor in achieving a result you are genuinely happy with.
In Ireland, the title 'architect' is protected by law. Only professionals registered with the RIAI (Royal Institute of the Architects of Ireland) can legally use the title. Registration requires a recognised degree, professional experience, and ongoing professional development. When you hire a registered architect, you are hiring someone with proven qualifications and professional accountability.
The most common reasons Irish homeowners hire architects are: house extensions (designing the layout, managing planning, overseeing construction), new builds (complete design from concept to certification), renovation of older or period properties, and interior redesign. Architect's fees typically run 8 to 12% of the build cost, which for a €50,000 extension means €4,000 to €6,000. This investment typically pays for itself in a better design, fewer construction problems, and higher property value.
Comparing at least three architects ensures you find someone whose design style matches your taste, whose fees are competitive, and who is available to take on your project within your timeline.

Typical pricing for architect services in Ireland (2026):
| Service | Typical Cost | Notes |
|---|---|---|
| Architectural design (extension) | €3,000 | €8,000 | Project size, complexity |
| Full architectural service (new build) | €15,000 | €35,000 | House size, design complexity |
| Planning application management | €2,000 | €5,000 | Project type, local authority |
Architect's fees are typically calculated as a percentage of the construction cost (8-12% for full service from design through to completion) or as a fixed fee for a defined scope. 'Full service' includes initial design, planning application, detailed drawings, tender management, and site inspections during construction. Partial services (design and planning only, without site supervision) cost less (5-8%). Fees vary by project complexity and the architect's experience. Dublin architects may charge more but are not necessarily more expensive percentage-wise.
What to Expect: The Architect Process
- Initial consultation. The architect visits, discusses your brief (what you want, budget, timeline), assesses the site, and presents initial ideas.
- Design development. Sketch designs are developed into detailed proposals with plans, elevations, and 3D visualisations.
- Planning application (if required). The architect prepares and submits the planning application, including all drawings and documentation.
- Detailed design and tender documents. Construction drawings, specifications, and a bill of quantities are produced for builders to price.
- Tender management. The architect helps you select builders, analyses quotes, and recommends the best value contractor.
- Construction oversight. The architect inspects the work at key stages, manages quality, and handles any issues that arise during the build.
- Certification. The architect (as assigned certifier under BCMS) issues the Certificate of Compliance on Completion.
Common Mistakes to Avoid
- Skipping the architect to save money. An extension built without proper design often results in poor light, awkward proportions, and building regulation issues that cost more to fix than the architect's fee.
- Choosing an architect based solely on fees. The cheapest architect may not have the design skills or experience for your project. Portfolio quality and references matter more than a percentage point difference in fees.
- Not checking RIAI registration. Unregistered designers cannot legally call themselves architects, cannot act as BCMS assigned certifiers, and may not carry professional indemnity insurance.
- Not communicating your budget clearly from the start. If the architect does not know your budget, they may design something you cannot afford. Be upfront about what you can spend.
- Not involving the architect during construction. An architect who only does design and planning, without site inspections during the build, cannot ensure the builder follows the design. Construction oversight is where many problems are caught.
What to Look for When Hiring an Architect Professional
Check that the architect is RIAI-registered at riai.ie. This confirms their qualifications and professional accountability. Review their portfolio to ensure their design style suits your taste. Ask for references from recent projects similar to yours. Professional indemnity insurance is mandatory. Be cautious of unregistered 'designers' or 'architectural technicians' offering design services at lower fees: while they may produce adequate drawings, they cannot act as assigned certifiers under BCMS and do not carry the same professional accountability.
Questions to Ask Your Architect Professional
- Are you RIAI-registered? Only RIAI-registered professionals can legally use the title 'architect' in Ireland.
- Can I see projects similar to mine? An architect experienced in your project type (extension, new build, renovation) will deliver a smoother process.
- What are your fees and what do they include? Understand whether the fee covers full service (design through completion) or partial service (design and planning only).
- How do you manage the construction phase? Site inspections during construction catch problems early. Without oversight, builders may deviate from the design.
- What is your availability? Some architects have long waiting lists. Ensure they can start your project within your timeline.
- How do you handle budget management? A good architect designs to your budget, not beyond it. Ask how they keep costs within your financial parameters.
Frequently Asked Questions
Full-service fees (design, planning, tender, construction oversight, certification) are typically 8 to 12% of the build cost. For a €50,000 extension, that is €4,000 to €6,000. For a €300,000 new build, €24,000 to €36,000. Partial service (design and planning only) costs 5 to 8%. Some architects offer fixed fees for defined scopes of work.
Not legally required for small exempt extensions, but strongly advisable. An architect ensures good design (maximising light, space, flow), regulatory compliance (building control, fire safety, energy), and proper construction oversight. The fee typically pays for itself in a better result and fewer problems.
An architect holds a recognised degree, is RIAI-registered, and can use the protected title. An architectural technician produces technical drawings and may handle planning applications but cannot act as an assigned certifier under BCMS. For straightforward projects, a technician may suffice. For complex or high-value projects, an architect provides a higher level of design and professional accountability.
Initial design concepts take 2 to 4 weeks. Design development to planning stage takes another 4 to 8 weeks. Planning permission (if required) takes 8 to 12 weeks. Detailed construction drawings take 4 to 6 weeks after planning. Total design timeline from first meeting to construction-ready drawings is typically 4 to 8 months.
The Building Control Management System requires a Commencement Notice before construction and a Certificate of Compliance on Completion. Your architect (as assigned certifier) manages this process, carrying out inspections during construction and issuing the final certificate. This is a statutory requirement for new builds and significant extensions.
A good architect designs to your stated budget, not beyond it. They make material and specification choices that deliver the best result within your financial parameters. During tendering, they analyse builder quotes and advise on value. During construction, they monitor costs and manage variations. Architects who design beyond budget without discussing the implications are not serving your interests.
