Architect in Castleknock, Dublin
Compare architect professionals in Castleknock. Free quotes, no obligation.
Castleknock is dominated by large, well-maintained family homes built from the 1980s to 2000s in estates like Castleknock Park, Beechpark, Carpenterstown, and Diswellstown. Housing is predominantly detached and semi-detached, three to five bedrooms, with good-sized gardens. Many homes are now 20 to 30 years old and reaching the point where boiler replacement, window upgrades, kitchen renovations, and energy retrofits are needed. The Phoenix Park boundary creates a distinctive western edge. Some older housing exists near the village centre.
Managed by Fingal County Council. A well-established, affluent family area with high property values (€500k to €1m+). The mature housing stock creates consistent demand for mid-life upgrades: boiler replacement, attic insulation top-ups, window replacement, kitchen and bathroom renovations, and garden landscaping. The area is relatively sheltered with good tree cover. Access for trades is generally good with driveways and parking. The established nature of the area means less new-build activity and more renovation and extension work.

Architect FAQs
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.
