Picking Materials Is a Gamble. Picking a System Is a Decision.
Designers and builders have thousands of individual products to choose from when formulating a wall build-up. Most of the time, those products were never designed to work together. Composite claddings trap moisture. Items conflict with each other The performance numbers on the spec sheet quietly disappear once everything is on site.
A RespiraSystem is different. It's a complete and balanced sequence of materials. Each layer chosen to play a part in a cohesive whole. Thermal mass paired with the right insulation. Breathable layers that move moisture out instead of trapping it. Natural finishes that tie it all together We've condensed everything we've learned across all of our projects into a range of deployable systems — plus the ability to customize hybrid configurations. You pick the system that fits your build. We back it up with full support: design, council liaison, install guides and on-site advice. Even link you with our network of installers.

TESTIMONIAL
Volume Builder Utilising Hempcrete
What they started with
This pilot project presented a unique challenge: a high-volume regional builder working on a steep site with brutal western sun exposure in Castlemaine. The goal was to prove that a high-performance wall system could replace standard lightweight construction without slowing down the rapid pace of a conventional residential build program.
The evolution
We deployed our "Cast & Block" hybrid system to meet both the schedule and the climate. By specifying 120mm RespiraBlocks on the critical western elevations, we created a massive thermal buffer exactly where it was needed. The system integrated seamlessly into the builder's workflow with zero delays, delivering a mainstream-ready home that combines the speed of volume building with the thermal resilience of a custom project.

TESTIMONIAL
Kew Secondary Dwelling
What they started with
The owners needed a compact secondary dwelling in their Kew backyard to serve as a teenager's retreat and guest space. However, they faced a common dilemma: while they wanted the speed and simplicity of a kit home, they were worried that a lightweight structure would struggle with the site's high sun exposure, leading to uncomfortable temperature spikes and a "temporary" feel.
The evolution
We transformed a standard kit frame into a high-performance sanctuary using our Clad & Block 120mm System. By lining the interior with solid hempcrete blocks and Rockcote lime plaster, we introduced critical thermal mass into the lightweight build. This stabilized the indoor temperature and softened the acoustics, proving that a secondary dwelling can be built fast while still feeling solid, permanent, and premium.

What You Actually Get From a RespiraSystem.
Five things every RespiraSystem delivers — no matter which configuration you choose.
Breathability, Non-Toxicity & Mould Control
Walls that manage moisture instead of trapping it. No interstitial condensation, no mould risk, no VOCs. The building envelope is honest — your indoor air stays clean because of how the wall is built, not because of an HVAC filter
Thermal Comfort & Low Energy Bills
R-values from R4.44 up to R7.01. Solid hempcrete walls store and release heat slowly — virtually eliminating the daily temperature swings that plague lightweight construction. Your heating and cooling systems work less. Your bills go down.
Building Longevity & Low Maintenance
Designed for 100+ years of service life. Lime and natural composites strengthen over time — the wall literally gets better as the home ages, not worse. No degrading synthetic insulation, no sagging, no rot.
Acoustic Comfort Built In
The combination of dense hempcrete blocks and Jeanius denim insulation (NRC 1.05 — at the top end of acoustic absorption) delivers a near-silent indoor environment without specifying separate acoustic products.
Fire (BAL) Rating
Hempcrete is naturally fire-resistant. Respira Systems are tested and rated for Australian bushfire-prone areas, giving you compliance and peace of mind in high-risk zones.
A Clear Path Forward
Whether you're ready to proceed, still in design, or months away from breaking ground — you'll leave with a sequence of next steps that makes sense for where you're at. No guesswork.

The Difference Between a House and a Healthy Home.
Most homes are built to compliance — the cheapest path to passing inspection. The walls are sealed, the insulation is synthetic, the air is recycled, and the comfort depends entirely on a heating and cooling system you'll spend the next 30 years paying to run.
A RespiraSystem is for the build where someone said let's do this properly. Where the materials store thermal energy instead of leaking it. Where the indoor air is clean because the building envelope is honest, not because the HVAC is filtering it.
That's what we mean by a system. Not a product. Not a material. A complete, engineered approach to building a home that works the way homes are supposed to work.
We've delivered this approach across 50+ Australian projects. We support builders, architects, and homeowners through the entire build — from the first conversation to long after move-in. Your project is our long-term commitment, not a transaction.

Frequently Asked Questions
Which RespiraSystem is right for my project?
It depends on your budget, your aesthetic, your build type, and your performance goals. Clad & Block is the most versatile and architecturally flexible — perfect when you want a specific exterior look. Premium Block & Block (from $288/m²) delivers the highest thermal performance available in any hempcrete wall system worldwide — for forever-homes, near-zero-energy targets, or extreme climates. We also offer Cast & Block, Block & Line, RespiraWool, and RespiraDrywall for specialist applications. Tell us about your project and we'll match you to the right one — or recommend a hybrid configuration.
How much does a RespiraSystem cost?
Clad & Block starts at $129/m² + GST. Premium Block & Block starts at $288/m² + GST. Other systems and configurations are quoted on application. Final pricing depends on specification, finishes, and project size — we'll quote tailored numbers once we understand your build. Most clients find that the upfront premium is offset within years through dramatically lower heating and cooling bills, lower long-term maintenance, and a building envelope that doesn't degrade.
Can I use a RespiraSystem on a renovation?
Yes. We adapt our systems to work with existing structures — preserving the character of heritage homes while introducing thermal mass, breathability, and clean indoor air. Renovations have different constraints than new builds, which is exactly why we ask about your project type in the form.
I don't have a builder or designer yet. Can you still help?
Absolutely. The form asks where you're at with both — and the answer doesn't change whether we'll work with you. If you don't have a designer yet, we offer Respira's concept design service. If you're still looking for a builder, we can connect you with builders in our network who already understand RespiraSystems. The earlier you bring us in, the better we can support the whole project.
Do I need a specialist builder, or can my regular builder install it?
Most conventional builders can install a RespiraSystem with our support. We provide technical install guides, on-site direction, and architect upskilling. RespiraBlocks lay faster than standard brickwork — about 30m² per day for a single leaf — and are ready to render within a few days. We've successfully worked with volume builders, regional builders, and owner-builders alike.
What's the R-value of each system?
Clad & Block: R4.44 standard, upgradeable to R5.27 with 120mm internal block. Premium Block & Block: R7.01 — the highest R-value available in any hempcrete wall system worldwide, delivering up to 40% superior thermal performance vs classic hempcrete construction.
How long does a RespiraSystem last?
Properly built, a RespiraSystem is designed for 100+ years of service life. Lime and natural composites strengthen over time — the wall literally gets better as the home ages, not worse.
Is RespiraSystem rated for bushfire zones (BAL)?
Yes. Hempcrete is naturally fire-resistant and our systems are tested for Australian bushfire-prone areas. We can provide BAL ratings and supporting documentation as part of your project quote — useful for council approvals and insurance.
Why so many questions in your form?
Because the right RespiraSystem depends on your build type, your budget, your timeline, your location, where you're at with builders and designers, and your performance priorities. The more you tell us upfront, the more accurate your quote — and the less back-and-forth before we can match you to the right system. The form takes about 2 minutes.
Can I get information without committing to anything?
Absolutely. When the form asks about your decision stage, just select 'Gathering information' or 'Just browsing.' We'll send system information and pricing without any sales pressure — and we won't follow up unless you want us to.
Frequently Asked Questions
Which RespiraSystem is right for my project?
It depends on your budget, your aesthetic, your build type, and your performance goals. Clad & Block is the most versatile and architecturally flexible — perfect when you want a specific exterior look. Premium Block & Block (from $288/m²) delivers the highest thermal performance available in any hempcrete wall system worldwide — for forever-homes, near-zero-energy targets, or extreme climates. We also offer Cast & Block, Block & Line, RespiraWool, and RespiraDrywall for specialist applications. Tell us about your project and we'll match you to the right one — or recommend a hybrid configuration.
How much does a RespiraSystem cost?
Clad & Block starts at $129/m² + GST. Premium Block & Block starts at $288/m² + GST. Other systems and configurations are quoted on application. Final pricing depends on specification, finishes, and project size — we'll quote tailored numbers once we understand your build. Most clients find that the upfront premium is offset within years through dramatically lower heating and cooling bills, lower long-term maintenance, and a building envelope that doesn't degrade.
Can I use a RespiraSystem on a renovation?
Yes. We adapt our systems to work with existing structures — preserving the character of heritage homes while introducing thermal mass, breathability, and clean indoor air. Renovations have different constraints than new builds, which is exactly why we ask about your project type in the form.

Dan Miles
Ima and Will at Respirabuilt are your natural building experts, leading the way on creative solutions that close the gap on traditional materials and processes. The whole process has been excellent but most refreshingly the post sales support has been exemplary. Despite being remote Will has been able to jump on video calls to walk myself and our builder through some of the more nuanced or trickier situations. Worth opening a dialogue if you're thinking about building with hemp.
David Wright
After losing our home in the 2019 bushfires, we rebuilt with hempcrete for greater resilience. The unrendered internal walls have a beautiful sandstone-like texture with natural layering patterns. Temperature stays comfortable even in the high 30s without any air conditioning or heating. Visitors are immediately drawn to the aesthetics. It's a resilient, sustainable home that accentuates our bush site in a way a standard build never could.
Jamie Triplett
Just finished a build in Lake Tyers, using hempcrete cast and block method supplied from the Respirabuilt team, the wall came up great. Thanks Will for the advice and knowledge to get us started. Regards Jamie Triplett
Beatrice D.
Respirabuilt supplied and installed hemp blocks for our new bungalow — we were so impressed with both the product and their workmanship. Will provided complimentary consultation to our builder throughout, making the process seamless. The 120mm blocks were perfect for our inner city block. We now enjoy wonderful thermal and sound insulation and healthy indoor air. Will and Ima are so passionate and knowledgeable — helpful, responsive and always available. I can't recommend them highly enough!
Chris Nunnock
We used Respirabuilt hempcrete blocks in a block and cast build. Will and his team were invaluable from planning through construction. As an owner builder, the two-phase wall approach made the project very manageable. Now in fitout, the thermal performance has been amazing — consistently impressing everyone who visits.
