One of our current renovation projects in Picton, Ontario. We’ve been busy taking this house back down to the bones — and uncovering exactly why performance matters.

Behind the old siding we found what too many homes are hiding:
water-damage, compromised joists, and insulation that had completely lost its effectiveness. Once moisture gets in, that old assembly doesn’t dry — it just slowly rots and leaks heat.

That means:
• higher heating bills
• cold drafts and uneven temperatures
• ongoing repair costs that keep coming back

Not to mention mould, animal and insect entry points…

And the materials we removed weren’t helping:
Vinyl siding and poorly detailed layers can trap moisture, while petroleum-based products come with a higher environmental footprint and don’t age well once water gets involved.

So we’re rebuilding it differently — with durability and sustainability in mind:

• Damaged wood removed and properly repaired (not covered up)
• Fully taped weather barrier for a true air seal
• Exterior mineral wool insulation that is vapor-open, fire-resistant, and built to last
• Rainscreen gap so the wall can actually drain and dry
• Switching to pine board & batten — renewable, repairable, and lower impact.

This isn’t just an upgrade — it’s a shift:
from a shell that traps moisture and wastes energy
to one that breathes, dries, and performs.

Better for the house.
Better for energy bills.
Better for the planet.

Can’t wait to see this beauty age well!

At Aerecura Sustainable Builders, we believe the way we build matters. From rammed earth construction to energy retrofits and sustainable renovations, every project we take on is an opportunity to work *with* the planet, not against it.

Natural materials. Timeless design. Future-forward thinking. Our homes are high performance, durable, and beautiful not just because our clients deserve the best but because our shared home does too.

Because sustainability isn’t a trend—it’s a responsibility. And we for the earth, with the earth.

RAMMED EARTH WORKSHOP @ PAPERKITE FARM

New this year, we’re adding an additional two-day, hands-on rammed earth workshop at .farm on September 12–13.

This workshop invites participants to learn how to design and build using traditional rammed earth techniques alongside Aerecura co-founder and master builder Graham Cavalier.

Together, we’ll construct a permanent rammed earth retaining wall for Judy and Hans’s farm, contributing to its evolving landscape in a meaningful and lasting way that reflects their continued dedication to sustainability and bio sequestering.

Participants will also have the option to enjoy a fresh lunch sourced directly from the market garden and tuck shop.

This workshop is eligible for OAA Continuing Education credits.

Spots are limited to just 20 participants to ensure a fully hands-on experience—register early to secure your place.

RAMMED EARTH WORKSHOP @ DROPSEED NURSERY
We’re excited to be returning to .pec this August long weekend for a two-day, hands-on rammed earth workshop.
Join Aerecura co-founder and master builder Graham Cavalier to learn how to design and build using traditional rammed earth techniques. Participants will gain practical, on-site experience while contributing to a permanent structure—the beginnings of Dropseed’s rammed earth greenhouse.
This workshop is eligible for OAA Continuing Education credits.
Spots are limited to just 20 participants to ensure a fully hands-on experience—register early to secure your place.

Careful planning, tight coordination, and a lot of precision went into making sure our client got exactly what they wanted — the outdoor shower of their dreams.

With rammed earth, there’s no trapped moisture and nowhere for mould to grow. The wall dries naturally in the sun, then holds onto that warmth — radiating it back so even an outdoor shower feels a little more comfortable.
Just rammed earth doing exactly what it’s meant to do.

Rammed earth season is here — and we’re kicking it off with something special.

We created the Aerecura workshop to build our very first off-site rammed earth project for installation on the ’s Lassonde Art Trail.

These forms are being built from designs Pedro created to echo the sculptural language and intent of Kara Hamilton’s piece — translating art into earth, material into story. We cannot wait to see the final piece revealed on the Trail.

This workshop marks the beginning of something bigger for us: a space to explore, test, and create. Expect more small-scale rammed earth installations, design-driven pieces, and collaborations to come, and follow along with us and as the Art Trail expands.

Aerecura is hiring an experienced carpenter to join our small, skilled team immediately for full time contract.

This position supports our Prince Edward County/ Kingston area crew, and preference is given to those within 1.5 hours of PEC. No rammed earth experience required, though of course there’s the opportunity to learn.

From an unfinished attic, poorly insulated and marked by years of water damage, to a light-filled primary bedroom and bathroom with the coziest of views.

We thought we’d share a small peek into this deep energy retrofit in Picton, Ontario. This family home is undergoing major changes to dramatically improve its energy efficiency, comfort, and overall feel.

We amended the roofline, added blown-in cellulose insulation, saved and restored a once water-damaged floor, and installed an energy-saving mini-split — which, thanks to proper insulation and air-sealing, hasn’t had to be turned on once.

Gone is the pull-down attic staircase. In its place, we built a floating stair tucked between two main-floor bedrooms (a reveal we’ll save for another day).

Why retrofit this home?
Because the most sustainable home is often the one you already have.
Because comfort matters — warm winters, cool summers, quiet rooms.
Because energy bills shouldn’t rise with every season.
And because thoughtful design can turn forgotten space into the most loved room in the house.

A retrofit isn’t just an upgrade — it’s a long-term investment in how a home feels, performs, and supports the people living in it.

Looking to live more comfortably in the home you’re in? We know how to and we’d love to make your house a home.

A grey and blustery week reminder of the sunny rammed earth walls at Salmon Point.

Rammed earth isn’t just about how good looks — it’s about good performance. These walls absorb warmth when the sun is out and release it slowly over time, helping keep the home comfortable through shifting temperatures and seasons.

Durable, low-carbon, and deeply connected to place, rammed earth is built for longevity — and for Ontario’s cold climate - especially these grey days.

Build better, build sustainably.

Did you see it? It can be so subtle that on a windy winter day—when clouds race overhead—you might miss it.

But when you catch it, you catch your breath.

Rammed earth walls don’t just sit in the light; they respond to it. As clouds pass, the surface shifts, quietly mirroring the movement of the sky. That beauty isn’t just visual—it’s physical.

Rammed earth walls have high thermal mass. They absorb heat when the sun touches them, store it deep within their layers, and release it slowly as temperatures drop. Even here, as a snow-lined retaining wall, you can feel that sense of warmth and stability—of a material doing exactly what nature designed it to do.

This is why rammed earth walls are such a natural choice:
they capture heat,
they temper the indoors,
and they hold the changing beauty of the landscape—
bringing science and beauty into the same plane.

Building with the earth, for the earth.
