Frequently Asked Questions

What is the average cost of a house extension?

The average cost can vary based on location, design, and materials, but in Dublin, it’s typical for homeowners to spend between €1,200 to €1,500 per square metre for a basic extension.

Do I need planning permission for a house extension?

Most house extensions require planning permission, especially if they alter the structure or appearance of the house. However, some minor extensions may be considered ‘permitted development’.

How long does a house extension take to build?

The duration depends on the project’s complexity. A simple single-storey extension might take 10-12 weeks, whereas a more complex two-storey extension could take upwards of 20 weeks.

How can I ensure my house extension matches my existing property?

Hire experienced architects and builders who can select matching materials and design styles that complement your existing property’s aesthetics.

Will a house extension add value to my property?

Yes, a well-designed and constructed house extension can significantly increase the value of your property, often by more than the cost of the project itself.

Can I live in my home during the extension work?

It’s possible, but it depends on the scale and type of extension. Some homeowners choose to stay, while others find temporary accommodation to avoid the disruption and noise.
