What is involved when building a Granny Flat

Learn about the construction process in this step-by-step guide.

1. Site Preparation

Clear the construction site and prepare it for building. This may involve removing any existing structures, levelling the ground, and ensuring proper drainage.

2. Foundation

Excavate and pour the foundation for the granny flat. The foundation provides stability and support for the structure.

3. Framing

Erect the structural framework of the granny flat. This includes constructing the walls, and roof trusses or rafters. The framing is typically made of timber and forms the skeleton of the building.

4. Windows and Doors

Install windows and external framing as per the design. Ensure they are properly sealed and meet energy efficiency and safety requirements.

5. External Brickwork

Apply the chosen external wall brickwork or cladding materials.

6. Roofing

Installation of the Fascia and Gutter, and then the roofing material, such as roof tiles or Colorbond sheeting, to create a weatherproof barrier.

7. Plumbing and Electrical Rough-In

Install the necessary plumbing and electrical systems within the walls and floors before they are covered. This includes laying pipes, installing wiring, and positioning outlets, switches, and fixtures as per the approved design.

8. Insulation

Install insulation in the walls and roof, to provide thermal and acoustic insulation, promoting energy efficiency and soundproofing.

9. Internal Fitout

Complete the interior fit-out of the granny flat. This includes installing internal walls, doors, architraves, skirting boards, and any built-in features, such as cabinetry or shelving. Flooring, such as tiles, laminate, or carpet, is also laid during this stage.

10. Plumbing and Electrical Fixtures

Install plumbing fixtures, including sinks, toilets, showers, and taps. Install electrical fixtures, such as light fittings, switches, power outlets, and appliances, as per the approved design.

11. Painting and Finishing

Apply paint or other finishes to the walls, ceilings, and trims. This stage also involves any necessary staining or varnishing of timber surfaces.

12. Final Touches

Complete any remaining tasks, such as installing mirrors, towel rails, door handles, and other fixtures. Conduct a thorough cleaning of the granny flat to prepare for occupancy.

13. Final Inspections

Arrange for final inspections by relevant authorities to ensure compliance with building codes, regulations, and safety standards. This may involve inspections for electrical, plumbing, and structural components.

14. Certification and Handover

Obtain the final certification or occupation certificate once all inspections are passed and requirements are met. Hand over the completed granny flat to the owner, ensuring all necessary documentation and warranties are provided.
