L’Echouage Residence: A Cottage That Rides the Tide

Bourgeois / Lechasseur architectes approached L’Echouage Residence like a careful nautical landing: keep what already knows the shoreline, then add only what the tides and rules will allow. Set on a thin finger of land along the St. Lawrence River, the project turns a modest cottage into a precise sequence of spaces that feels both anchored and quietly adventurous.

Keeping the original, on purpose

The brief started with demolition and a clean-slate rebuild, because humans love erasing things and calling it progress. But the first site visit flipped the script. The existing cottage had a rare closeness to the water, a simple form, and a covered terrace aimed straight at the horizon, plus a maple grove that already did the hard work of making the place feel intimate.

So the strategy became preservation with a twist: restore the cottage to maintain its grandfathered position near the river, then extend the home through a discreet addition connected by a bridge. That bridge is not just circulation, it is a transition device that turns moving between volumes into a small moment of arrival.

Designing inside a shrinking footprint

Even with a generous site, the buildable zone is squeezed by rising water levels and shoreline protection setbacks with irregular boundaries. Instead of forcing one big object into a tight outline, the design breaks into separate pavilions placed where construction is permitted, while the original cottage remains in its nonconforming perch above the river.

Preserving the cottage demanded real structural work: lifting it to install new piles, reinforcing floors, walls, and roof, and upgrading insulation across the envelope. The lift is also pragmatic, improving resilience as water levels fluctuate, without turning the house into a bunker.

A program that moves like the tide

The plan reads as a sequence. The original cottage holds the main living spaces, fully oriented to the river and washed in daylight. A subtly rotated east pavilion captures morning sun for the primary bedroom, keeping private life slightly apart from the communal core.

A third volume becomes an accessory dwelling unit for the clients parents, oriented toward the western bay. The separation supports cohabitation without awkward overlap, giving each unit its own sense of privacy while still feeling like one family compound.

Cedar, shadows, and framed landscapes

Formally, the new pavilions echo the cottage rooflines, with silhouettes that hint at beached hulls and the erratic boulders scattered by shifting tides. From the ground, the ensemble still reads like a small cottage settlement. Only from above does the full scope of the intervention reveal itself.

Material does the rest. Cedar cladding appears in two tones: darker boards on primary faces to suggest weathered coastal wood, and lighter cedar tucked into cutouts and sheltered recesses to emphasize depth. That paler cedar continues inside, blurring interior and exterior so the landscape stays present. In the end, Bourgeois / Lechasseur architectes make the expansion feel less like an addition and more like a set of calibrated responses to site, tide, and light.
