Your backyard. A home for someone you love.

Your Backyard Could Be a Home for Someone You Love — The Duo-Forma01
Most backyards in Sydney are underused. A patch of lawn, maybe a shed, a Hills Hoist that hasn’t moved in years — space that sits quietly while life gets more complicated around it.
Meanwhile, the people you love are dealing with problems that space could actually solve. A parent managing well for now, but not forever. A grown child priced out of every suburb they’d want to live in. A sibling who needs a proper base while they get back on their feet. These are real needs, held by real people — and right now, there may be a solution sitting in your own backyard.
That’s exactly what the Duo-Forma is designed for. Keep Modular builds this fully self-contained, two-bedroom home in our Sydney factory, then installs it in your backyard in as little as one to three days.
Not a Granny Flat, but A Proper Home
Most people picture a boxy studio with a kitchenette crammed into one wall. Functional, perhaps, but barely liveable. The Duo-Forma 01 is something genuinely different.
At 54sqm, it delivers two bedrooms, a bathroom, a compact kitchen, and open living space — a home in the truest sense. Someone can live here with real comfort and dignity, without feeling like they’ve accepted a compromise. The design reflects that commitment: stacker door entry, a minimalist palette, open living connected to an optional timber deck. It doesn’t look like an afterthought. Instead, it looks like it belongs.

Close Enough to Matter. Separate Enough to Feel Like Theirs.
The conversations that lead people to enquire about the Duo-Forma 01 tend to follow a familiar pattern.
There’s a parent getting older, still independent, still wanting their own front door, but the idea of them living an hour away starts to feel like the wrong call. There’s a son or daughter who has been saving for years and is still nowhere near a deposit. There’s someone in the family going through something hard, who needs stability more than anything else right now.
The Duo-Forma 01 solves a problem that money alone can’t always fix: proximity. It gives you the ability to be genuinely close without anyone giving up their independence. Furthermore, two bedrooms means it works for more than one person — a couple, a parent and child, or someone who needs both a guest room and a bedroom of their own. That flexibility matters more than most people realise until they need it.

What It Adds to Your Property
The emotional case for a secondary dwelling is obvious. However, the financial case is equally worth understanding.
A self-contained two-bedroom dwelling on your Sydney property is a genuine asset. In a market where space is scarce and housing pressure shows no signs of easing, secondary dwellings consistently add value and appeal — both for liveability and for what a future buyer sees when they walk through. Additionally, if your circumstances change, the Duo-Forma 01 can generate rental income as a separate secondary dwelling, subject to council approval and zoning.
It’s not built as an investment vehicle — but it can certainly function as one. And because it’s modular, the cost and disruption of adding it is far lower than a traditional in-situ build of the same size and quality.
Built in Croydon. Delivered to Your Site.
Keep Modular manufactures the Duo-Forma at our factory on Parramatta Road in Croydon, the same facility where every one of our modular builds takes shape.
Factory construction means your backyard stays yours throughout the process. While your home remains undisturbed, our team builds the Duo-Forma off-site under controlled conditions. Once it’s ready, we transport and crane it into position. Installation takes as little as one to three days — a timeline that traditional construction simply can’t match.
Our Cooma project is a strong example of the Duo-Forma on a rural residential site: two bedrooms, a considered interior, delivered well outside the metro area. The Berrilee project, on the other hand, shows how the same product adapts to a different set of site conditions. In both cases, the result is a home that feels right for where it lands.
How it works
The process from first conversation to handover follows Keep Modular’s integrated delivery model:
- Site feasibility — we assess your backyard for access, slope, services and council requirements
- Design and approvals — DA or CDC depending on your site and local council
- Factory manufacture at our Croydon facility — typically four to six weeks
- Site preparation, transportation and crane installation — often completed in one to three days
- Completion, connection and handover
The full process is outlined on Our Process page. We’re also happy to walk you through it in person — the factory is open for visits and it’s the best way to understand what modular construction actually looks like up close.
How the Process Works
Keep Modular’s integrated delivery model takes you from first conversation to handover through five clear stages:
- Site feasibility — we assess your backyard for access, slope, services, and council requirements
- Design and approvals — DA or CDC depending on your site and local council
- Factory manufacture at our Croydon facility — typically four to six weeks
- Site preparation, transportation, and crane installation — often completed in one to three days
- Completion, connection, and handover
We’re also happy to walk you through the process in person. The factory is open for visits, and consequently, it’s the best way to understand what modular construction actually looks like up close.
Is the Duo-Forma 01 Right for Your Site?
Most standard Sydney residential lots can accommodate a secondary dwelling, but every site has its own conditions. Setbacks, easements, slope, existing structures, and council zoning all factor into the assessment. Therefore, the best starting point is a straightforward conversation. We’ll give you an honest picture of what’s possible, what approvals are likely to be required, and what the process looks like from here.

The Space Is Already There
Most people who build a Duo-Forma 01 tell us the same thing afterwards: they wish they’d done it sooner.
Not simply because the build is fast (though it is). Rather, because the problem they were putting off, the conversation they weren’t sure how to start, turned out to have a straightforward answer sitting in their own backyard.
