Granny Flat Builder in Camden and Macarthur
What a Granny Flat Can Do for Your Family
A secondary dwelling on your property opens up several lifestyle and financial options. Most of our clients in Camden and the Macarthur growth corridor build a granny flat for one of these reasons.
Rental income. A self-contained granny flat in this region can generate weekly rent that often makes a significant contribution to mortgage repayments. With strong rental demand across South West Sydney, a one or two bedroom granny flat is a steady long-term investment.
Space for parents or in-laws. A separate dwelling on the same block lets older family members live close by without losing their independence. They have their own kitchen, bathroom, and living area, and you have the peace of mind of having them nearby.
A teenage retreat or studio for older kids. Older teenagers and young adults often need space to study, work, or simply have their own quiet area. A granny flat keeps them on the property while giving everyone room to breathe.
A home office or studio. Working from home has become permanent for many families. A free-standing studio creates a clear separation between work and family life. You can see how this works in our Camden free standing studio project, which doubles as guest accommodation when needed.
Granny Flat Designs We Build
We build granny flats that suit your block, your budget, and the way the space will be used.
Attached granny flats
They share a wall with the main house. This option works well on smaller blocks where land is limited, and it can be more cost effective because some services and structural elements are shared.
Detached granny flats
These sit as a separate building on your property. This is the most popular option for families wanting a true second dwelling with privacy and independence. Detached builds also tend to deliver stronger rental returns.
One or two bedroom layouts
These are the standard configurations. A one bedroom design suits singles, couples, or a single parent. Two bedrooms add flexibility for visiting family or a small share arrangement.
Studio designs
They offer an open plan layout without internal walls separating the living and sleeping areas. Studios are popular for home offices, guest accommodation, and short-stay rental.
Granny Flat Approvals in NSW
Most granny flats in NSW are approved as a Complying Development under the State Environmental Planning Policy. This pathway is faster than a Development Application and is available to most properties that meet the standard requirements.
The main rules are: the block needs to be at least 450 square metres, the granny flat must not exceed 60 square metres of internal floor area, and there are setback rules from boundaries that vary by lot size. Site coverage limits and access requirements also apply.
If your property does not meet the standard requirements, a Development Application through council may still be possible. We assess your block during the initial site visit and confirm which pathway applies before any drafting begins. We handle all paperwork, lodgement, and certifier coordination so you do not have to deal with council directly.
What Affects the Cost of a Granny Flat
Granny flat costs depend on several factors. We provide itemised fixed quotes with clear allowances so you know exactly what is included before any work starts.
The main variables are total floor area, attached or detached build, level of finish, site conditions, and connections to existing services. A flat block with simple access and standard finishes costs less than a sloped block with premium finishes and complex service connections. We include certifier fees, council contributions, drafting, and construction in our fixed quotes.
For older homes, we sometimes need to upgrade existing electrical, sewer, or stormwater infrastructure to accommodate the new dwelling. We assess this on site and include any required upgrades in the quote, rather than discovering them mid-build.
Our Process
Token Building follows a structured five-stage process for every granny flat project.
1. Site visit and consultation. We come to your property, talk through your goals, and assess the block for slope, services, setbacks, and approval pathways.
2. Design and drafting. We prepare working drawings that suit your needs and meet all CDC or DA requirements. We coordinate with structural engineers and certifiers where required.
3. Approvals. We lodge the application and manage the process through to approval. You do not have to chase council or certifiers.
4. Construction. Our team handles excavation, concrete work, framing, roofing, plumbing, electrical, and interior fit-out. We coordinate trades and keep you informed at every stage.
5. Final handover. We complete final inspections, organise occupation certificates, and walk you through the finished dwelling.
A granny flat sits naturally alongside our broader range of home extensions, second storey additions, and room additions. If you are weighing up which option suits your property best, we can walk you through the trade-offs during the site visit.
