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.

Frequently Asked Questions

Common questions about house extensions in Kildare.

Do I need planning permission for a house extension?
Many extensions are exempt if they're under 40m² to the rear, don't exceed certain height limits, and meet other conditions. We can advise on your specific situation and help with planning applications if needed.
How much does a single-storey extension cost in Kildare?
Single-storey extensions typically cost €1,800 to €2,500 per square metre in the Kildare area. A typical 30m² rear extension costs roughly €54,000 to €75,000 including VAT. We provide detailed, fixed quotes before work begins.
How long does a house extension take to build?
A single-storey extension typically takes 12 to 16 weeks from breaking ground. Two-storey extensions take 16 to 24 weeks. Planning permission, if required, adds 8 to 12 weeks before building starts.
Can I live in my house during the extension?
Yes, in most cases. We plan the work to minimise disruption. There will be some noise and dust, but we keep the site tidy and secure access to your home throughout.
Do I need an architect for a house extension?
For larger extensions or those requiring planning permission, an architect or architectural technician is recommended. For smaller exempt extensions, detailed drawings from a technician may suffice. We can recommend trusted professionals in the Kildare area.
What's included in your quote?
Our quotes cover all labour, materials, structural work, plastering, plumbing, electrics, and finishing. We detail everything line by line so there are no surprises. The only extras would be items you choose to add during the project.
