Granny flat costs in Dublin typically range from €40,000 for a basic garage conversion to €80,000+ for a purpose-built extension with full kitchen, bathroom, and separate entrance. The overall cost depends on the size of the space, the construction method, specification of finishes, and whether planning permission is required. A garage conversion into a self-contained granny flat averages €35,000–€50,000, while a purpose-built garden extension averages €60,000–€80,000. We provide detailed, transparent quotes after visiting your property and discussing your requirements.

Planning permission requirements for granny flats in Dublin depend on the construction method. Converting an existing garage into a granny flat often qualifies as exempt development. However, building a new structure or extending your home to create a granny flat will typically require planning permission from your local authority. All granny flat projects must comply with building regulations regardless of planning status. We assess your property, confirm exactly what's required, and manage any planning application on your behalf from start to finish.

A granny flat conversion from an existing garage typically takes 8–10 weeks from start to completion. A purpose-built granny flat extension takes 12–16 weeks depending on size and specification. If planning permission is required, add 8–12 weeks before construction can begin. We provide realistic timelines during consultation and keep you updated throughout the entire build with minimal disruption to your daily life.

Yes, a self-contained granny flat can be rented out under the Revenue Commissioners' Rent a Room Relief scheme, allowing you to earn up to €14,000 per year tax-free if you also live in the property. Alternatively, a fully separate unit may be subject to standard rental regulations. We recommend consulting a tax advisor regarding your specific situation. From a construction perspective, we ensure your granny flat meets all the required standards for a habitable, self-contained dwelling.

A well-built granny flat typically adds €40,000–€70,000 to the value of a Dublin property, often exceeding the cost of construction. The additional self-contained living space is highly attractive to buyers, particularly families with elderly relatives or those looking for rental income potential. Most Dublin homeowners find it one of the highest-return investments they can make in their property.
