The Top 7 Two-Storey Home Builders in Perth: Who’s Really Worth Your Time in 2025?
If you are thinking about building a two-storey home in Perth, then chances are you know that you are far from the only one thinking of doing the same, and that there is a very competitive market when it comes to home builders in Perth. Two-storey homes are ideal because they offer more space and better zoning and allow you to save money by utilising a smaller land footprint, but choosing the right builder? That’s when the whole process starts to get more than a little complicated.
If you’re planning to build in Perth and you want your home to be everything you imagined and more, it is vital that you take the time to choose the best two-storey home builders in Perth, but with so many options open to you, how do you pick the ones who will offer great build quality, customer service, inclusions, timelines, and design flexibility ? By letting us help you with our list of the seven best two-storey home builders in Perth for 2025, that’s how…
And yes, there’s a clear standout.
Notable for: Fast, high-quality two-storey builds without the usual delays
Topping our list is 101 Residential, and for good reason. While many builders offer flashy marketing, 101 Residential backs it up with a consistent track record of delivering thoughtfully designed two-storey homes faster than most of the competition.
They use a hybrid construction method (brick on the ground level, timber frame above), which not only reduces build time but also offers design flexibility. Their floorplans are family-friendly and cleverly laid out – think sculleries, alfresco areas, home theatres, and extra living zones as standard, not expensive upgrades.
101 Residential is setting the benchmark in Perth for accessible two-storey living with strong customer satisfaction, excellent value, and genuinely liveable homes.
If you want a smart, stylish, double-storey build without dragging out your timeline or blowing your budget, they’re the clear pick.
Notable for: Creative urban infill and narrow block designs
Residential Building WA specialises in making the most of compact lots and inner-city locations. Their team is experienced in complex site requirements and planning regulations, making them ideal if you’re building in a tricky suburb or on a tight lot.
They offer custom solutions, contemporary façades, and the ability to modify existing plans. They’re especially popular with those looking to build infill homes or maximise street presence with striking architectural designs.
Notable for: Contemporary design and smart technology integration
Smart Homes for Living brings a modern approach to homebuilding. Their two-storey homes include sleek, functional layouts with a focus on energy efficiency and tech upgrades. Think solar integration, smart lighting, and zoned air conditioning.
Their designs also cater to lifestyle-focused buyers, with kitchens as the centrepiece, open-plan living areas, and entertainment-ready spaces. A strong choice for those who want their home to work smarter, not just look good.
Notable for: Larger floorplans and family-focused features
Ventura Homes has been serving Western Australia for over 20 years and consistently ranks among the state’s most reliable builders. Their two-storey options focus on generous proportions, thoughtful zoning, and family-friendly layouts.
They’re particularly strong in the northern suburbs and regional fringe, offering more space for growing households. Their build times are average but reliable, and customer support gets strong reviews, especially post-handover.
Notable for: Customisable designs with an independent builder feel
If you’re looking for a boutique experience with full design flexibility, Activa Homes Group is worth a look. While smaller than some of the big-name builders, they offer a more personal, collaborative process, and their two-storey builds feel fully tailored to your lifestyle.
Their team handles everything from design to completion in-house, which means you won’t be passed between departments. That consistency often translates to smoother communication and a better overall experience.
Notable for: Entry-level two-storey homes with a youthful vibe
B1 Homes is part of the Scott Park Group (just like 101 Residential), but it’s aimed more at first-time buyers and younger families. Their two-storey options are compact, cost-effective, and designed to maximise value on smaller blocks.
While they don’t offer the premium finishes you’d find elsewhere, they’re transparent about what’s included and make the process approachable for buyers new to building. A great “starter” builder if you’re stepping up to two storeys for the first time.
Notable for: Fully bespoke, high-end two-storey builds
Looking for something truly custom and aren’t worried about budget?
Cassari offers architecturally designed homes with complete design freedom.
These are not volume homes, they’re one-off builds created around your vision, block, and lifestyle. From floating staircases and home lifts to wine cellars and rooftop terraces, if you can dream it, they can build it. Best suited for buyers who want to make a statement and aren’t in a rush.
