3-Bedroom Granny Flats Ireland

A three-bedroom granny flat is a full family home in every meaningful sense. With three separate bedrooms, a spacious living room, a kitchen area, and a bathroom, a three-bedroom granny flat can comfortably accommodate a family of four or five, provide independent living space for a couple and a regular guest, or serve as a comprehensive holiday home or long-term rental on the family property. At pineca.ie, our three-bedroom granny flat range offers substantial timber structures built to the highest residential standards, insulated for year-round use in Ireland's climate.

Three-bedroom granny flats

The NICOLE M (68 m², 44 mm + cladding) is our flagship three-bedroom granny flat, designed to comfortably accommodate up to six people in three separate bedrooms with a generous living room and full bathroom facilities. Its contemporary cladded exterior and mobile-home classification make it a versatile and potentially planning-exempt solution for Irish families who need substantial residential space on their property. An insulated version is available for comfortable year-round use.

Three-bedroom garden lodges

Our larger garden lodge models provide three-bedroom family home quality in a permanent timber residential building. With up to 90 m² of internal living space, these structures feature three dedicated bedrooms, spacious living and kitchen areas, full bathroom facilities, and in many cases a generous covered terrace. Built from 44 mm or 66 mm slow-grown conifer with comprehensive insulation, these are genuinely substantial homes designed to provide comfortable, dignified independent living for many decades.

When a three-bedroom granny flat is the right choice

Three bedrooms make sense when the granny flat will be home to a family rather than an individual or couple, when extended family will be staying regularly and separate sleeping spaces are needed, when one bedroom will serve as a dedicated office or hobby room, or when a multi-generational household involves grandparents plus adult children or grandchildren. Three bedrooms also significantly increase the versatility and rental market value of the structure if circumstances change over time.

Planning considerations for three-bedroom structures in Ireland

Three-bedroom granny flats are substantial structures. The mobile-home-classified NICOLE M may still qualify as planning-exempt in many situations, but we strongly recommend verifying with your local authority before proceeding with a structure of this scale. Larger permanent residential structures will generally require a planning application.

Questions & Answers

How much space does a three-bedroom granny flat typically cover?

Our three-bedroom granny flat models range from approximately 68 m² (NICOLE M) to 90 m² and above in the larger garden lodge range.

Contact our team at +353 1 699 4541 for specific floor plan dimensions on any model.

Are three-bedroom granny flats available fully insulated in Ireland?

Yes – all our three-bedroom models are available with comprehensive insulation for year-round residential use. The NICOLE M is available in an insulated 44 mm + cladding version; our three-bedroom garden lodge models are available with twin-skin 44+44 mm, high-quality insulation, or 66 mm log construction with insulation. For permanent full-time residential use in Ireland, we strongly recommend the insulated specification. Call us at +353 1 699 4541 to discuss the right insulation specification for your budget and use case.

Can a three-bedroom granny flat be used as a rental property in Ireland?

A three-bedroom granny flat that has been granted planning permission for residential use can be rented out in Ireland, subject to the terms of any planning conditions and standard tenancy law. Rental income is subject to income tax. The planning and legal requirements for a rental residential unit differ from those for a family-use annexe, so we recommend taking appropriate professional advice. Our team can discuss the structural and specification options – call us at +353 1 699 4541.

What foundation does a three-bedroom granny flat need?

A three-bedroom granny flat of 68–90 m² requires a robust, fully engineered concrete slab foundation designed to the load requirements of the structure. The slab must be level, solid, well-drained, and fully cured before the building kit is delivered. For a structure of this scale, we strongly recommend engaging a structural engineer to design and certify the foundation.
