Two Bedroom Granny Flat Investment Project: Charmhaven NSW

This recently completed two-bedroom granny flat in Charmhaven, on the Central Coast of NSW, was delivered to a young Sydney-based investor couple.

Using our Wamberal design floorplan with project-specific refinements, it combines a bright, efficient layout with low-maintenance finishes suited to long-term rental appeal.

It is possible to build Granny Flats without any council approval – even more reason to consider a granny flat in your backyard for a family member or investment!

This granny flat uses our Wamberal open plan design to create a bright kitchen and living zone with well separated bedrooms. Standard inclusions span ceiling fans with LED lighting, a 3.5 kW reverse cycle system, stone benchtops, durable cladding, metal roof and gutters, powder coated aluminium frames and a feature entry door. Total construction cost (in 2022) $239,079, excluding landscaping. At P J Cook Building, standard means exceptional quality from design through to finish.

Testimonials

  • Karenne Jurd 

    We have recently completed a lovely build with PJCook and we couldn’t be happier – Peter and his whole team are a pleasure to work with. They consistently had an eye to the detail, levering off their successful experience, to improve the delivery for our construction – whether it was site management, finish details, materials pallets, or subcontractor management. Any issues that arose were addressed in a timely, respectful way. We now have two lovely homes (a 2 bedroom and a 3 bedroom), after subdividing a residential block, occupied by happy families. 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
