Did you know it is possible to build Granny Flats without any council approval – even more reason to consider building a granny flat within your backyard for a family member or investment!

One-Bedroom Granny Flat Project: Erina (Entrance Rd), NSW

This 1-bedroom granny flat in Erina was built as a comfortable alternative to aged care for our client’s mother. Designed using our Branxton 1-Bedroom Granny Flat floor plan, with slight modifications to meet specific requirements, this project brought the family closer together while offering modern comfort and independence.

Situated on The Entrance Rd, a busy RMS-managed road, the project faced challenges with limited traffic control windows, complicating coordination of trades and deliveries. Fortunately, we secured access through a neighbouring property on a quieter council-managed road, allowing longer work periods. However, the steep, tiered yard required us to construct a ramp-style walkway for safe site access. Additionally, the property’s location in a BAL 29 bushfire-prone area demanded strict compliance with construction standards, adding further complexity and cost. Managing traffic control, deliveries, cranes, trucks, excavators, and trades within set timeframes required meticulous planning and administrative oversight.

At P J Cook Building, we thrive on overcoming challenges, whether working on bushfire-prone areas, steep terrains, or difficult-to-access sites, delivering quality results every time.

Details & Inclusions

This Granny Flat in Erina is a fantastic example of how a well-planned design can have a positive impact on your property. Granny Flats are a cost-effective living option and require less maintenance than a larger home, which is perfect in this scenario as it allows the Mother to be close to family whilst maintaining an element of privacy.

  • Kitchen: The kitchen features Quantum Quartz Zero Stone benchtops with a breakfast bar, complemented by a split pantry with a central microwave opening. The cabinets are finished in Polytec Melamine Classic White Matt, offering a sleek and clean aesthetic. Overhead cabinets feature a finger-pull handleless design for a minimalistic look, while Regal pull handles are used for lower cabinets, pantry doors, and drawers. High-quality appliances, backed by a standard 5-year warranty, add to the kitchen’s practicality.

  • Bathroom & Vanities: This space is designed for both style and functionality, with floor-to-ceiling tiling and square-set ceilings creating a polished look. The custom vanity, crafted in Polytec Melamine Classic White Matt with a Quantum Quartz Zero Stone top, matches the kitchen for a cohesive design. A semi-frameless shower screen is paired with a half-height shelf wall for convenient storage of personal items. Additional touches include a frameless mirror over the vanity, enhancing the room’s modern appeal.
  • Flooring: The main living areas have 4.5mm luxury vinyl plank flooring in the Berlin colour, which delivers durability and elegance. Bedrooms and wardrobes feature plush carpet in Urban Grey, which provides warmth and comfort.

  • Paint & Finishes: The internal walls are painted in Haymes Greyology 2, with doors and woodwork finished in gloss for added durability and style. Roller blinds in Whisper White complete the clean and understated design.

  • Exterior & Cladding: The exterior of the home boasts 300mm BGC Cladding painted in Haymes Greyology 5, adding a modern and durable finish. The covered front patio is designed with a lined ceiling for a seamless aesthetic. Entry doors are bushfire-rated (Hume BFR4) and paired with Bradnams aluminium frames in Textura Pearl White. Timber entry posts are painted in Haymes Greyology 2 for a cohesive look.

  • Bushfire Compliance: To meet bushfire safety standards (AS3959–2018), aluminium leaf guard gutters and fly screens have been installed. These features ensure compliance while maintaining the home’s aesthetic appeal.

  • Additional Features: A Bradford Windmaster whirlybird and eave vents have been installed for improved ventilation, enhancing airflow and overall comfort within the home. This design seamlessly combines modern aesthetics with practical features, ensuring both functionality and compliance with bushfire standards.

What could be better!

  • Elize Smit

    We are very happy with our 2 bedroom backyard granny flat from PJ Cook. The built started just when Covid restrictions happened so we were a bit apprehensive but there was no delay. What a professional team – from the planning phase to the finished product. This was a bit of a tricky built because we have a battle axe property but it didn’t seem to be a problem for Peter and his team. The granny flat solved our problem of a growing family and also is a really good investment down the track.

  • Robert Cogswell

    P. J. Cook Building. Built a 2 bed Granny Flat in our backyard at Chain Valley Bay. The project finished on time and without any additional expenses This was extraordinary considering the pandemic. My Wife and I are extremely happy with the finished product. The builders eye for detail is second to none. I wouldn’t hesitate to use this company again. This is one of the best investments we have made. To sum up the experience. Trust, Perfection, Value and Reliability.

  • Julie Bramall

    Thank you to the Team at PJ Cook Building for the build of our Granny Flat on our investment property. Peter was quick to respond to any questions that we had. Once the project got started, it was very quick to completion, especially over the Covid19 period. There were a few hurdles along the way, which had nothing to do with PJ Cook but Peter made this much easier to deal with and we are very appreciative to him.
    The finish product of our Granny Flat is impeccable. Peter’s eye for detail is impressive, which has resulted in the most beautiful Granny Flat (inside and out) that I have ever seen. We were able to secure a tenant only 2 days after advertising and for a very impressive return.
    Thanks to all the Team at PJ Cook Building and especially Peter. We would not use any other builder if and when we decide to build another.

  • Jo Minter

    I am so very happy with my Granny Flat built by PJ Cook in Woodberry. The whole team onsite were courteous and professional at all times. The quality of my build is impressive. It took me over a year of looking at other builders before settling with PJ Cook. The only disappointment is that the slide out range hood was unobtainable, so I settled for a fixed one. I am sure I can live with that. Absolutely no hesitation to recommend them to anyone looking at building a granny flat. Handover is tomorrow. I am one very excited and happy customer. Jo

  • Mark Brogan

    “Peter and team are first class”.

    From the initial quote, communications, build to completion – it was perfect! From the initial quote the team were on time, respectful and even set out the build with pegs for a visual! The build started and was well underway seemingly in an instant.

    The quality was exceptional with a true value for money. Peter and the team put in the effort and focus on the detail. The team went above and beyond with the authorities for approvals and complexities with service connections!

    We could not be happier with the outcome and credit to the team. With our first baby on the way, the wife and I couldn’t be happier with our stress free build. We will be recommending PJ Cook to our friends and if the future allows, going again with the team!

  • Tanya Watson

    We employed PJ Cook in 2016 to put in a 2 bed granny flat for us.

    Peter was extremely professional from the start. Great communication all the way and has certainly been the best thing we ever did to generate a great investment income!

    I named our granny flat “Happy Cottage Woy Woy” as it is holiday accommodation and it makes people feel happy.

    I would highly recommend PJ Cook builders
