Most rear extensions up to 40m² don't need planning permission
Subject to height limits and other conditions. Every property is different — we'll advise on your specific situation when we visit for your free quote.
What We Offer
Every extension is different. Here are the main types of house extension we build across Kildare and surrounding counties.
Single-Storey Extensions
The most popular choice for adding a kitchen, living space, or sunroom. Typically 20-50m² with minimal disruption to your daily life.
Two-Storey Extensions
Maximise space without using more of your garden. Add bedrooms, bathrooms, and living areas over two floors.
Rear & Side Extensions
Open up your home to the garden with a rear extension, or use the side passage for a side return. Popular for open-plan kitchen-diners.
Attic Conversions
Convert unused attic space into bedrooms, offices, or playrooms. Often exempt from planning permission.

Up to 40m² Without Planning Permission
Under Irish planning law, many single-storey rear extensions up to 40m² are exempt from planning permission — meaning you can get started sooner with less paperwork.
General Exemption Conditions
- Single-storey to the rear of the house
- Total area of extension does not exceed 40m²
- Does not reduce private rear garden below 25m²
- Maximum height limits are met
- No previous exempted extensions on the property
Every Property Is Different
These are general guidelines — whether your extension qualifies depends on your specific property, any previous extensions, and local conditions. There's no substitute for a proper assessment.
When we visit for your free quote, we'll assess your property and advise on planning requirements for your specific project. If planning permission is needed, we'll guide you through the process.
