Granny Flats and Ancillary Accomodation

Granny Flats

Ancillary accommodation (commonly known as “granny flats”) are small, self-contained dwelling on the same lot as another single house. It may be attached to the main house, integrated with the main house or a separate building to the main house altogether. Ideal for accommodating aging parents, adult children or independent teens, ancillary dwellings are providing alternative solutions for affordable housing in Perth.

Inner-ring suburbs such as Melville, Bull Creek, Leeming, Kardinya, Queens Park, Belmont, Bassendean, Morley, Dianella, parts of Maylands, Balcatta and Osborne Park have seen a surge in ancillary accommodation as these suburbs tend to have big blocks, good tenant demand and high rental returns that could soon cover the initial cost. However, with more and more people of all ages embracing low maintenance living, there is significant demand for this type of accommodation throughout the metropolitan area.

Until recently, planning regulations permitted only a direct family member of the main house to occupy an ancillary dwelling. However recent changes to State Planning Policy Residential Design Codes have made it possible to earn potential rental income from non-family members. Ancillary dwellings can now be used to accommodate long-term guests or to provide housing opportunities for private tenants, carers, unrelated seniors and students. Another option often passed over is to rent out the primary dwelling and move into your down-sizer granny flat when your old home outgrows you!

Whether you’re looking for ways to maximise your site’s potential – and profit, or you’re simply seeking to accommodate a growing family or successful home business, a granny flat can be a versatile and cost effective way to expand your floor space. Remember though, your biggest return on investment will be the time you invest at the planning stage, so if you’re considering building a granny flat or under-taking a renovation, addition or extension project, you’ll want the team at Shelford Quality Homes by your side from the outset.

Our Granny Flat Process

At Shelford Quality Homes, our granny flat service follows a well-organised and structured process to ensure your project proceeds smoothly with minimal disruption and no nasty surprises.


The Shelford Quality Homes granny flat process begins with an obligation-free consultation. Before we put pen to paper and any plans are drawn, prices calculated or agreements signed, we like to get to know you over a cup of coffee (or a glass of wine)! We come to you, wherever you live in Perth, and talk through your ideas while offering the benefit of our experience. We aim to gain a good understanding of your expectations, and to give you a thorough understanding of our own abilities. We believe the key to a successful partnership is all in the planning, so our collaborative approach to design  commences by building a comprehensive profile based on your needs, your wants and your budget. Please proceed to our CONTACT US PAGE if you’d like to make an enquiry


Armed with the information gathered at our initial visit, we return to measure up your home and to take some photographs, to check for easements for services like sewerage, and to consider any existing features (like trees and swimming pools) that might impact on your granny flat design. We estimate a budget for your project and provide you with an overview of what’s involved, before producing a conceptual plan and a specification. You may be asked at this time (depending on the complexity of your project) to sign a Preliminary Design Agreement (PDA) and pay a one-off design fee to allow us to further develop the drawings required to bring your dream home to life!


Once you are happy with the design for your granny flat and agree to proceed, you’ll be asked to sign a Preliminary Agreement and pay a further fee. This fee covers the costs incurred on undertaking on your behalf any additional preliminary work, including a site visit from our Structural Engineer, necessary to fine tune your plans and provide you with a final (fixed) contract price. You will also be invited to attend our Dixon Road Selection Studio where our qualified Interior Design Consultants can provide practical and professional advice on not only your colour and product selections, but also the little things that will make your granny flat, a stunning addition to your home!

Permits and Approvals

Shelford Quality Homes will then take care of all the necessary permits and approvals for you, helping to avoid unnecessary costs and delays by liaising with local authorities about building boundaries, covenants and zoning. We will provide you with sound advice about achieving good urban design outcomes, and we will also address any concerns your neighbours might have about your renovation, addition or extension project. We will then ask you to sign a contract for the work you have asked us to undertake (for your added peace of mind, Shelford Quality Homes uses the standard Housing Industry Association of Australia Fixed Price Contract).
