Modular House Designs in Ireland
Modular house designs have come a long way from the "one size fits all" cabin. Today's modular homes in Ireland range from compact studios to spacious 3-bed family homes, all customisable to your site, budget and lifestyle. This guide walks through the main modular house designs, sizes and custom options available in Ireland.
The Main Modular House Designs
Studio / Garden Room (15–25m²)
A single open space — ideal as a home office, yoga or music studio, gym, or a place to relax away from the main house. Often planning-exempt up to 30m² as an ancillary garden structure.
1-Bed Modular Home (35–55m²)
A self-contained one-bedroom home — perfect as a granny flat, starter home, rental unit or holiday let. Includes a bedroom, bathroom and open-plan living/kitchen.
2-Bed Modular Home (55–80m²)
Two bedrooms, a bathroom and an open-plan living, kitchen and dining area. A popular choice for small families, couples wanting a guest room, or a holiday home.
3-Bed Modular Home (80–110m²)
Three bedrooms, a family bathroom and a large open-plan living, kitchen and dining area. A genuine family home — and a common choice for a first self-build.
Custom Options
Modern modular house designs are highly customisable:
- Layout — open-plan vs separated rooms, bedroom count
- Insulation level — standard to A-rated for lower running costs
- Solar panels — integrated for lower energy bills
- Cladding — cedar, render, brick or timber
- Glazing — full-height windows, bifold or sliding doors
- Kitchen and bathroom fit-out — your choice of spec
Choosing the Right Design for Your Site
- Small city garden — a studio or 1-bed
- Family plot — a 2- or 3-bed
- Rural / holiday site — a 2-bed with a view
- Rental investment — a 1-bed or studio
