Granny Flats

Granny flats are a versatile solution for families, investors, and homeowners looking to maximise their property. At JMAR Building Co, we design and construct custom granny flats that are functional, comfortable, and built to the same high standard as our homes.

Whether it’s for extended family, rental income, or future flexibility, we create secondary dwellings that feel like a home. Not a compromise.

Build Bigger. Build Better. With JMAR Building Co.

Why Build a Granny Flat

A well-designed granny flat can:

  • Provide independent living for family members
  • Generate rental income
  • Increase overall property value
  • Offer future-proof flexibility

Our designs prioritise privacy, natural light, and efficient use of space.

Custom Design & Quality Construction

We don’t use one-size-fits-all designs. Each granny flat is tailored to:

  • Your block size and layout
  • Council requirements
  • Intended use (family or rental)
  • Long-term durability and comfort

Our team handles the process from design through to construction, ensuring clarity and confidence at every stage.

A Seamless Building Experience

With JMAR Building Co, you can expect honest advice, quality workmanship, and a straightforward process. Delivered on time and within budget.
