Hurlstone Park · Rear extension and full renovation
One long room, gathering light
Under hoop pine boards,
one long room gathers the light:
dinner starts early.
Haiku Building · Sydney and the Illawarra
Healthy, high‑performance renovations for the house you’ll stay in.
Inner West and Illawarra families. Airtight, ventilated and low-tox, priced before we start, built once.
Hurlstone Park. Rear extension and full renovation.
Blower-door tested
Every house we seal to an airtight standard with a ventilation system gets a blower-door test. The number tells us it’s as tight as we built it to be.
Full Pro Clima system
Membranes and tapes that make the building airtight and let it dry out, not one or the other.
WUFI moisture modelling
We model where the water vapour goes before we build the wall, so mould has nowhere to start.
Priced before we start
A paid feasibility stage, then a fixed-price contract built from real numbers.
Healthy home
What the people inside breathe and touch
Most of what makes a home healthy is invisible once the plaster is on. The materials and what they give off. Where the moisture goes. Whether the air moving through the house is fresh or just recirculated.
We hold those to the same rigour as the energy performance. A house built to passive house standards without thought for off-gassing materials, the right ventilation system and the health of the people who’ll live in it can cause more problems than it solves. We build the whole thing.
The work
Three homes, finished and lived in
Alexandria · Heritage terrace, rebuilt from within
The city, kept at the front door
Behind the old brick,
winter sun on dark timber:
the city, far off.
Marrickville · Rear extension
A few square metres, properly spent
A few square metres:
enough for the morning sun
to change everything.
The invisible work
The part of the house you’ll never see is the part that keeps you well
Finished kitchens are easy to photograph. This is the work underneath them, and the reason the finished room stays warm, dry and quiet.
The Clarity Process
Free quotes are a guess. Know before you commit.
On a renovation, the biggest risk is a contract price that turns out to be wrong. So before you sign anything, we do two rounds of paid work: first on the existing site, then on the drawings. What we find goes into the fixed price instead of coming back as a variation mid-build.
Todd leads every Clarity Process meeting himself. The fee is fixed and we tell you what it is at the first conversation.
01
Enquiry
You tell us about the house. We tell you plainly whether we’re the right fit.
02
First conversation
You read how we work first, then we talk about what you want from the home.
03
Site and feasibility
Paid. We find what’s hidden in the ground and the existing structure, on paper, before it becomes a variation mid-build.
04
Design development
Paid. We take off the documented scope and price it line by line, refining across three proposal rounds until scope, inclusions and number line up.
05
Proposal
A fixed-price proposal built from real trade and supplier numbers. Not an estimate.
06
Contract
Walked through in full before anyone signs. Then the deposit is lodged.
07
Build, handover, defects
One point of contact. Weekly site meetings. The home we hand over is the one we priced.
A straight answer
We’re not the right builder for everyone
Good projects come from good fit. Here is ours, stated plainly. It saves everyone time.
We’ll work well together if you…
- Want a forever home that’s healthy to live in and stays comfortable year-round, not a quick flip
- Are working with an architect or designer, or want help finding the right one
- Want real numbers before you commit, and accept that takes a paid feasibility stage
- Care what your family breathes: low-tox materials, filtered air, no damp
We’re probably not your builder if you…
- Want the cheapest quote. We don’t cut corners, so we don’t win those jobs
- Are running a tender for new work. We don’t tender, we partner
- Need it rushed. Quality takes the time it takes
- Want a builder who just follows orders. We’ll have the difficult conversation if the house needs it
From the owners
What it’s like on the other side
Three homeowners, in their own words. More on Google.
“The space is now light, bright, silent to the outside noises, and just a lovely place to be in. The process with Todd was effortless from beginning to end. The planning of the build was straightforward and collaborative, Todd listened to my goals and each step of the way was willing to make modifications or suggest improvements to get me the results I wanted.”
“On a daily basis, everyone in the company was a pleasure to be around: they worked diligently, cleaned up every day, and made the whole process enjoyable while I lived on site.”
“Todd and his team demonstrated stellar craftsmanship throughout our renovation project. They made the process smooth and stress-free for us. Can’t wait to work with Todd again.”
“Seriously impressed with Todd and his team. Prompt, professional, considerate and consciencious; I have and would recommend Haiku.”
