How building projects should be run
Building work goes best with clear drawings, a written specification and an agreed scope before anyone starts. Many Dublin homes can be extended to the rear without planning permission within exempted development limits, but structural changes need an engineer, and larger projects may need planning permission and Building Control notices.
What usually affects the price:
- Size and complexity of the build
- Foundations, ground conditions and site access
- Structural steel and engineering
- Specification of finishes, kitchens and glazing
- Design, planning and certification fees
What to check before you hire a builder
- Ask for a fixed-price, itemised quote based on drawings and a specification
- Check they are on the Construction Industry Register Ireland (CIRI)
- Confirm public and employers' liability insurance
- Agree stage payments tied to milestones, not dates
- Make sure an engineer or architect signs off structural work and compliance

Frequently Asked Questions
Do I need planning permission for an extension?
Rear extensions of up to 40 square metres can be exempt, subject to conditions on size, height and remaining garden space. Check with your council or an architect.
Do I need an architect or engineer?
Structural work needs an engineer. Larger projects benefit from an architect to design the work, handle permissions and certify compliance.
How long does an extension take?
A typical single-storey rear extension takes around three to four months on site, plus design and approval time beforehand.
How should I pay a builder?
In stages tied to milestones such as foundations, roof and completion, with a small retention held back until snags are fixed.
How much does a builder cost in Dublin?
It depends on the job. Our building cost guide lists typical Dublin prices for each service, from €300–€3,000 for general building repairs upwards.
