Granny Flat Builders Campbelltown

Campbelltown sits in the heart of the South West Sydney growth corridor, and its generous suburban blocks make it one of the best places in the region to add a granny flat. Larger lots give you room to build a comfortable second dwelling without crowding your existing home, and that space translates directly into rental income and property value. 5 Star Granny Flats brings design, approvals and construction together under one roof so your Campbelltown project runs smoothly from start to finish.

As specialist granny flat builders in Campbelltown, we know how much opportunity the local land offers under complying development. Many blocks across the area qualify for the fast-track approval path, and we help you take full advantage of it. You get a single, accountable team managing every stage of your granny flat in Campbelltown.

Approvals in Campbelltown: CDC vs DA

There are two main approval routes for a granny flat in Campbelltown. A Complying Development Certificate is the faster option for blocks that meet the standard planning rules, and it suits many of the area’s larger lots. A Development Application through Campbelltown Council applies where a site sits outside those rules or within a specific planning zone.

A complying development granny flat generally needs at least 450 square metres of land, a 12 metre frontage, a 3 metre rear setback and 0.9 metre side setbacks. We confirm exactly which path suits your property during a free site inspection and manage the whole approval process for you.

Granny Flat Designs That Suit Campbelltown Blocks

The larger blocks common across Campbelltown give you real design freedom. Two bedroom layouts of around 60 square metres are popular here because the land can easily accommodate them, and they attract strong rental interest from families. If you have the space and the demand, a 3 bedroom granny flat offers even more living area and rental appeal. Explore our granny flat designs to see the full range.

We tailor every design to the way your block sits, taking in orientation, access and outlook. Standard inclusions cover a floor to ceiling tiled bathroom, soft closing cabinets, quality appliances and a separate electricity meter, so your granny flat is ready to live in or lease from day one.

One Bedroom Flats

Great for people on a small budget and with limited space. It can easily accommodate one or two adults.

Two Bedroom Flats

Ideal for small families for two to four people. This can be rented out because they're relatively spacious.
