Granny flats here fall into two groups
Granny flat work splits into new builds and refits of older flats. A new granny flat starts with the block. NSW allows a secondary dwelling of up to 60 square metres, usually on a lot of at least 450 square metres, with setbacks that depend on the lot. Our post on granny flat size and setback rules goes through the numbers, and the Wollongong granny flat page covers the process for the city.
Refitting an older granny flat
Where a Russell Vale property already has a granny flat that was built years ago and is showing it, a refit usually starts with the wet area, since a worn bathroom and kitchen are what tenants notice. Insulation and glazing come next, because older flats are often cold in winter and hot in summer. The home renovations page explains how we run this kind of job.
The first question is approval. If an older flat was built without it, a certifier can say what is needed to regularise it. Settling that before the interior work saves money, because fittings put in before approval may need to come out again. Our post on granny flat council approval explains the two routes.
Budgeting
Cost depends on size, finish level and site work such as the slab, the sewer connection and power. Read the granny flat cost guide and the post on granny flat costs in NSW before setting a figure. For layout choices, the granny flat designs page shows common configurations, and how long a granny flat takes to build gives a schedule. For a new flat, that post puts design and documentation at a few weeks for a fairly standard build, stretching to a couple of months for a custom layout or an awkward block.
Rental or family use
Both uses work, but the design differs. A rental benefits from a separate entry, a private outdoor space and low-maintenance finishes. A flat for family is often designed around accessibility and closeness to the main house.
Insulation and comfort in older flats
Many older granny flats were built to a budget, with thin roof insulation, no wall batts and single glazing. They get hot in summer and cold in winter, and tenants notice. Adding ceiling insulation, wall insulation where the lining is being replaced and better windows lifts comfort and cuts running costs. Our post on BASIX and energy ratings for new homes explains the standards new dwellings are built to, which is a useful guide for what to aim for in a refit.
The switchboard and the smoke alarms are worth checking in an older flat as well, since either can be well behind current requirements, and any upgrade belongs in the same proposal.

Questions from Russell Vale
Can you renovate an existing granny flat in Russell Vale?
Yes. A refit can cover the kitchen, bathroom, linings, insulation and flooring. If the flat was never approved, we advise on the certifier steps first so you do not spend on an interior that cannot be signed off.
What is a granny flat makeover worth doing first?
Bathroom and kitchen usually give the biggest change, followed by insulation and windows for comfort. We check the structure and waterproofing before the cosmetic work.
How much does a granny flat cost to build in Russell Vale?
It depends on size, design and site works, so we quote after seeing the block. Our granny flat cost guide lists what drives the number.
How big can a new granny flat be?
Up to 60 square metres of floor area (measured to the outer face of the external walls) as a secondary dwelling. Setbacks, the shape of the lot and the sewer position may make the largest flat your block will take smaller.
Does a new granny flat in Russell Vale need development approval?
Not always. If the block and the design meet the complying development rules, a private certifier can approve it. Overlays, an unusual lot shape or a larger design send it to council.
