Families across Ireland are looking for flexible ways to create additional living space. A modular granny flat in Ireland can provide an independent area for parents, adult children, guests or other household needs without undertaking a large traditional extension.

Modular Home Ireland offers turnkey ancillary units designed to provide self-contained accommodation. These units are manufactured off-site and delivered to the property, creating a potentially faster and more controlled route to additional living space.

What Is a Modular Granny Flat?

A modular granny flat is a self-contained accommodation unit manufactured using off-site construction. Depending on the model, it can include a bedroom, bathroom, kitchen and living space.

Unlike a simple garden shed or storage building, an appropriately designed ancillary unit can be intended as genuine living accommodation. Planning and building requirements must always be checked for the individual property and intended use.

Who Can Use a Modular Granny Flat?

Accommodation for Parents

A granny flat can give parents their own private living environment while keeping them close to family. This can provide a useful balance between independence and accessibility.

Accommodation for Adult Children

Young adults can benefit from having a separate living area while remaining on the family property. A self-contained unit can provide privacy without requiring a separate rental property.

Guest Accommodation

For families who regularly have visitors, a dedicated accommodation unit can offer a comfortable alternative to using bedrooms within the main house.

Home Office

A larger ancillary unit may also provide space for a home office, studio or work area, subject to the planning and permitted use of the property.

What Modular Granny Flat Sizes Are Available?

Modular Home Ireland currently publishes several ancillary unit

options. Published examples include units of approximately 25m², 33m², 45m² and 55m², with configurations ranging from one to two bedrooms.

Published starting prices include approximately €61,950 for a 25m² Type 1, €78,850 for a 33m² Type 2, €94,450 for a 45m² Type 3 and €113,850 for a 55m² Type 4. Prices and specifications can change, so the latest quotation should always be confirmed directly with the supplier.

What Is Included in a Turnkey Granny Flat?

One of the main attractions of a turnkey ancillary unit is the level of completion. Modular Home Ireland’s published information describes turnkey units with features including kitchens, bathrooms, flooring, heating and appliances, alongside delivery and installation.

This can reduce the amount of finishing work required after the unit arrives on the property.

Are Modular Granny Flats Energy Efficient?

Energy efficiency is important for any independent living space. Modular Home Ireland describes its ancillary units as energy efficient and publishes specifications including insulation, steel-frame construction and A1 BER certification for its listed units.

The final energy performance of any building depends on its complete specification, heating system, ventilation, windows, airtightness and use.

Do You Need Planning Permission for a Granny Flat?

This is one of the most important questions to answer before ordering an ancillary unit. Planning requirements can depend on the property, the location of the unit, its size, its intended use and the applicable planning rules.

Homeowners should not assume that a building is automatically exempt from planning simply because it is manufactured off-site or located in a garden. Professional planning advice should be obtained for the individual project.

Modular Home Ireland states that its ancillary service includes design and planning support, helping homeowners understand the requirements before installation.

How Long Does a Modular Granny Flat Take?

Modular Home Ireland states that its ancillary units can be factory-built in approximately 8–14 weeks, with installation following site preparation. The actual project timeline can vary

depending on planning, site conditions, access and the selected unit.

What Should You Consider Before Buying?

  • Available garden space
  • Access for delivery and installation
  • Planning requirements
  • Connection to water and electricity
  • Wastewater arrangements
  • Groundworks and foundations
  • Number of bedrooms required
  • Intended use of the accommodation
  • Overall project budget

Why Choose a Modular Granny Flat?

For homeowners who need additional accommodation but do not want a lengthy traditional construction project, modular construction can provide a practical alternative.

The factory-built approach can reduce on-site construction and provide a more controlled manufacturing environment. A turnkey package can also simplify the process by bringing design, manufacturing, delivery and installation together.

Is a Modular Granny Flat Right for Your Property?

The answer depends on your site and requirements. A large garden with good access may provide an excellent opportunity for a modular ancillary unit, while a restricted site may require additional design consideration.

The best approach is to establish the planning position and site requirements before selecting the final model.
