        Our Tips on Designing Custom Floor Plans for Your Granny Flat

        Granny Flat Solutions is an industry leader in building custom-designed Granny Flats. In our more than 40 years as Granny Flat builders, we’ve never encountered two the same. While we offer a wide designer range of 1, 2, 3, and 4-bedroom Granny Flats to suit any block of land or budget, we understand that everyone’s needs are different.

        If a custom Granny Flat is the right option for you, use this guide to help you with the process of creating a unique floor plan. By taking into consideration design elements that cater to both functionality and aesthetics, your dream Granny Flat could be just a few weeks away.

        3 Basic Steps to Designing Custom Granny Flat Floor Plans

        A floor plan is an essential part of building a Granny Flat. A high-quality floor plan should increase the enjoyment of the space, ensuring an easy flow within.

        Before construction can begin, you’ll need to have a floor plan design that meets your preferences. From maximising natural light to the number of bedrooms you require, here are the key steps when designing your dream Granny Flat from scratch.

        Step 1. Choose a Custom Granny Flat Builder to Work With

        Find Granny Flat builders who work in your location and be sure to read their testimonials, visit their display homes and view their portfolio.

        When you choose Granny Flat Solutions as your builder, we can give you a free Granny Flat site consultation. You can learn more about zoning, permits, and Granny Flat regulations in NSW here.

        Step 2. Consider the Design Features You Can’t Live Without

        Once you understand where on your property you can build your Granny Flat, you can begin to think about the dimensions, the style of the building, the different rooms you require based on the purpose and number of occupants, and the features you want to include.

        For example, if the Granny Flat will be used as a home office, you might design it with fewer bedrooms and more flexible space. Natural light and ventilation will also be key considerations. If you have a narrow block on which to build a Granny Flat, you might consider a straight-line design with bedrooms at different ends.

        If your Granny Flat is designed to house elderly family members or those with a disability, accessibility requirements will be important. You might need expert advice on features such as easy-to-access storage, bathroom layout and dimensions, kitchen functionality, and backyard accessibility.

        Step 3. Hire an Architect to Refine Your Custom Floor Plan

        An architecture firm can help bring all of your ideas together to formulate a floor plan that meets the necessary regulations and building standards. Their expertise ensures the dwelling fulfils its purpose. For example, that doors don’t open into one another and that you have enough windows to fill the home with natural light.

        An architect can also help you prepare the documentation you will be required to lodge with your local council and can help you overcome any roadblocks you may encounter.

        Practical Tips for Designing a Custom Granny Flat Floor Plan

        While a Granny Flat is only a small space, it’s worth making functionality a priority. Here are some practical tips to consider when designing a custom floor plan:

        1. Designing a flexible space can add more value to your home. While you want your Granny Flat to suit your current requirements, planning for different uses in the future can make your primary dwelling more valuable should you choose to sell in the future, so be flexible where you can.
          Granny Flats offer a limited amount of space. To maximise functionality, think carefully about how to use every square metre. You might incorporate multi-functional or built-in furniture or adopt smart storage solutions to keep the space free of clutter.
        2. Get a professional team to help with the lighting and electrical planning. Good planning is key to functionality, so ensure you consult the experts when it comes to having an adequate amount of power points and lights for the right situations.
        3. A home office will have specific requirements. For example, are you comfortable sitting with your back to the door? Can your computer monitors be positioned so that they are not facing windows to avoid glare? Can filing cabinets be fully extended? Do you have enough storage?
          A tall ceiling is an optical illusion that adds to the sense of space. Raked or cathedral ceilings will make your Granny Flat feel brighter and more spacious. Larger doors and windows can also bring in more natural light.
        4. EXTRA TIP: Choose materials that are easy to maintain. From flooring to benchtops and wall paint, choose finishes that are durable and easy to keep clean, no matter your planned purpose.
