Our in-house design team takes care of the entire approvals process for you, from start to finish, including initial concept and design to engineering and council approval. We can modify any of our designs to fit your particular site requirements and accommodate your design needs.

Popular Lake Macquarie granny flat designs

After years of building granny flats, we understand what our clients for their builds. One of the popular trends we have seen is a number of granny flats with large decks. Decks are a popular choice in the Lake Macquarie region for all types of properties, as they provide extra utility and entertaining space. 2-bedroom granny flats are also a popular choice for Lake Macquarie families, as they are able to house their loved ones while maintaining their own space.

Given the unique challenges of the properties in Lake Macquarie, we often build custom-designed granny flats for our clients. Check out our gallery of floorplans and be sure to ask us about our custom design process.

Testimonials

"A big thank you to Backyard Grannys for my new abode. I found BYG on the internet and I can thoroughly recommend them to do the build. From the very beginning BYG have been very professional, easily contactable and easy to discuss the build with. The layout has taken everything into consideration that I will need now and into the future. Not to mention it has added considerable value to the property. A big shout out to Brett Tubnor, my project manager, who kept me updated and dealt with any questions I had in a timely and professional manner. Also to the staff in the office in particular Lynne, thank you. I have no hesitation in recommending BYG."

Victoria Driscoll

"Backyard Grannys were very professional, each step was explained clearly and all communication was easy to understand. Our site supervisor Brett was super organised, kept us informed of all progress and ensured all finishings were high quality. I would highly recommend Backyard Grannys."

Katherine Cody

"Backyard Grannys built our 2 bedroom Granny Flat, from the getgo we have had the BEST experience. They talked and walked us through the whole process and timings of when things would occur. We live 6 hours from where the building will be built, the communication was excellent and the upgrades we requested where done straight away, we made the colour selections over the internet which was just so easy, they called to confirm our selections and if there were any changes due to manufacturers issues they were onto us to let us know and a like for like products where used. The built was quicker than we expected and the handover occurred on the OCT long weekend, Graham walked us through the Granny and it is far better than we expected, the attention to detail and the quality is superb. Would I build with them again 110%. Do yourself a favour and check them out you will not be disappointed."

Craig Sharp

"We would like to say a very sincere thank you to all at Backyard Granny’s, we mean everyone starting with Alex Mitchell the Managing director of the company right through to the truck driver who cleans the yard. We were blessed to have found this wonderful company. From day one they made us feel so special and the advice, communication and support was beyond words. I have been involved in the building industry for over fifty years and have never found a company to go to such lengths to make sure we were kept up to date with every step of the build.The workmanship of the project from day one right through to the handover of the keys was beyond belief. It was easy to understand just how much Alex ( Managing Director) takes so much pride in his Backyard Granny’s Flats and how he has managed to make sure this flows so smoothly throughout his whole team which also includes his contractors. We also need to say a special thank not only to Alex but Aemelia McCorb Architectural Designer, Lynne Tarlinton, Lynne Smart Client Service Officer and Erin Murray Administrator. A special mention has to go to Graham Smith who was our Project Manager. Graham’s dedication and commitment to look after our build was outstanding and his commitment to make sure that every detail plus all communication was important to us as if he was building the flat for himself.Regards - Roy & Julie Leslie"

Julie Leslie

"We could not be happier with our new Granny flat. BG’s was so supportive and provided the very best service imaginable from the first visit to the display, to getting the keys. Our Project manager Graham Smith is irreplaceable and made everything easy and efficient. The team were always available to listen and provide guidance and support when needed. Lynne is just the best and kept us up to date along the way. We could not have asked for more and would recommend the company to anyone."

Sarah-Jane Daniel

"After a rocky start with sales staff we were appointed brett tubnor as project manager from that first call from brett my mind changed about backyard grannys we had the pleasure working with brett and all he’s trades we found him to be honest and if there was a problem he would ring i would recommend backyard grannys in the future."

Wayne Guthrie

"We just had our Granny Flat completed (Jan 2025) and myself and my wife are very pleased with the results. Backyard Grannys were flexible enough to incorporate a design which was generated by my wife utilising an off the shelf design/architecture computer program. Backyard Grannys then used this as the basis to complete an up to regulatory specification Granny flat design.Having heard so many horror stories of people having difficulties and severe disagreements with their builders, we found Backyard Grannys superior ethics and customer focused ethos to be a most unexpected pleasant surprise. We sincerely hope that Backyard Grannys never changes that aspect of your business, as in our case it has served you well, and gained you loyal and satisfied clients.The staff at Backyard Grannys are exceptional. From the sales and design team, to Backyard Grannys CEO Sarah Gow (who personally inspected each stage of the build) . Our site manager Aaron Mullins in particular was awesome. He took our calls no matter how busy he was and made himself available to address any questions, requests or concerns we may have had resolving all such queries promptly and to our satisfaction. A very client focused outfit.We would highly recommend Backyard Grannys to anyone. They were very responsive to requests and questions, and when we were told something, it was done without fail. Pretty great building experience overall. Dealing with Newcastle City Council......., well that's another story😆Pete and Michelle Evans21st of February 2025"

"Great service at BYG right from the start. Josh was very thorough with his quote and also recommend Axon cladding which was slightly different to the original cladding I wanted but the Axon cladding really made the granny flat stand out! Aemelia was really great and meshing the whole design together!Highly recommend talking to Josh for any of your granny flat ideas!"

Shannon Allen

"The whole team at Backyard Granny’s have been fantastic to work with. The contractors were each different but carried on their work requirements quite professionally. While at first the process seemed a bit stressful for me, I have to say that I couldn’t have picked a better team than Backyard Grannys - everyone was so easy to work with and nothing was too much trouble, with special thanks to the project manager Riley. I also want to thank the office staff too, especially Lynne, who was the best person to help guide me whenever I needed to ask questions. Overall I’m extremely happy with the end result and could not recommend them highly enough."
