L. McComber Builds a Multigenerational Retreat Around a Giant Oculus in Charlevoix
Le Grand Bercail gathers several families under one hyper-insulated timber roof on a rocky cape above the Saint Lawrence River.
Cap-à-l'Aigle sits on a rocky cape above the Saint Lawrence in Charlevoix, a region where winters are long, landscapes are vast, and timber construction is less a stylistic choice than a cultural reflex. L. McComber's Le Grand Bercail was designed to host several families at once, not as a collection of private suites but as a single domestic landscape organized around a double-height festive heart. The result is a house that feels communal without sacrificing retreat, generous without sprawling.
What makes the project genuinely interesting is the precision with which it balances two competing ambitions. On one hand, it wants to belong to its site so thoroughly that it reads as a natural formation among the birches and firs. On the other, it deploys serious passive-design engineering: hyper-insulated glazing 40 percent beyond code requirements, airtightness of 0.35 air changes per hour, deep roof overhangs calibrated to reject summer heat while harvesting winter sun. Le Grand Bercail is a reminder that the most romantic-looking houses in Quebec are often the most technically rigorous.
A Silhouette Built for the Treeline



The exterior presents a steep gable clad in vertical wood planks, crowned by a standing-seam metal roof that will age and patina alongside the surrounding boreal forest. The palette is deliberately restrained: wood tones, metal greys, the occasional warmth of clay brick at the base. From a distance the house registers as a barn or chapel silhouette, a deliberate move that lets it defer to the conifers and birch trunks framing every sightline.
The eight-foot-diameter oculus punched into the gable wall is the house's signature gesture. It is large enough to transform the upper floor into a lantern at dusk, visible through the trees like a signal fire. By day it floods the attic study with soft, omnidirectional light. It is also a structural dare: cutting a circle that size into a load-bearing gable requires careful engineering of the timber frame around it, and the detail drawings reveal how that geometry was resolved.
The Gallery and the River


A deep covered porch wraps the south face, supported by slim steel columns and sheltered by a plywood-lined ceiling that reads as an extension of the interior. This gallery is not decorative. In a climate that swings from minus-thirty winters to humid summer heatwaves, it acts as a thermal buffer, shading glazing in July while allowing low winter sun to penetrate. It also provides a year-round outdoor room with unobstructed views of the Saint Lawrence, a body of water wide enough here to look like an inland sea.
Inside, the timber-lined dining room makes the most of those river views with a large picture window framing a single pine tree in the foreground and water beyond. The framing is deliberate: rather than a panoramic glass wall, McComber chose a composed aperture that makes the landscape feel like something you look at, not something that presses in on you.
The Festive Heart



The center of the house is a double-height volume that opens onto both the living room and the landscape. A clay brick wall anchors the space on one side, its herringbone pattern carried through to the floor around the wood-burning stove. On the opposite side, a glazed timber partition separates the living room from the dining room, allowing light and sound to pass while giving each space its own identity. The tongue-and-groove wall paneling, painted in pale tones, keeps things bright without going clinical.
This central room is where the multigenerational program makes itself felt most clearly. It is scaled for gatherings: high enough to breathe, wide enough for a crowd, warm enough (thanks to heated floors and the stove) that people will linger. The corridor leading off from it, with its brick herringbone floor and vertical paneled walls, connects the communal core to the private sleeping wings without ceremony.
The Staircase as Sculptural Spine



The Douglas spruce staircase is not just vertical circulation; it is the house's spatial engine. It starts at the entry hall, where terracotta tile meets white paneled walls, and climbs through a curved balustrade to an upper landing bathed in light from the oculus above. The handrail follows a continuous curve that feels hand-shaped, which it essentially is: Le Grand Bercail was crafted by local carpenters, tinsmiths, cabinetmakers, and tilers, and the joinery throughout reflects that investment.
At the top of the stair, the circular window reveals itself at full scale. Morning light pours through it onto the curved timber railing, casting shadows that shift across the vaulted ceiling throughout the day. The landing doubles as a threshold between the attic study and the mezzanine play area, giving the stair a purpose beyond mere connection.
The Oculus and the Attic Study


The bedroom-office tucked under the roof is the quietest room in the house and possibly the best. Low bookshelves line the knee walls, and the vaulted ceiling follows the pitch of the roof, compressing the space in a way that feels protective rather than cramped. The oculus dominates the gable end, framing the coastal landscape in a circle of timber that turns the view into something closer to a painting than a window. It is a room designed for concentration, and it works.
Sleeping Quarters: Suites and Bunkrooms



The bedrooms are organized into two parent-children suites grouped in a separate wing near the entrance, a layout that keeps nighttime noise away from the communal core. The rooms are modest in size but rich in detail: vertical tongue-and-groove paneling, timber-framed windows positioned to catch pine branches and snow, and a material warmth that makes each room feel like a cabin within the larger house.
At the garden level, a dormitory with built-in timber bunk beds opens onto the woodland, giving the house its most camp-like quality. The sleeping platforms feature integrated storage cubbies and horizontal windows that sit at mattress height, so the view is the first thing you see when you wake. It is a smart move for a house that needs to accommodate variable head counts: the bunkroom absorbs overflow without anyone feeling like they drew the short straw.
Kitchen and Wet Rooms



The kitchen occupies the far end of the plan, benefiting from views in multiple directions. A timber island with three stools serves as the informal gathering point that every good family house needs, and the proportions are generous enough that cooking for a crowd does not mean working in a corridor. The connection to the dining room is direct but not fully open, preserving the option of closing off kitchen chaos during a meal.
The bathrooms are handled with the same material care as the rest of the house. A curved shower alcove lined with small square tiles over terracotta flooring introduces geometry you do not expect in a rural timber house. An arched mirror and sphere sconce in the powder room nod to a softer, almost Art Deco sensibility that keeps the interiors from feeling monotonously woody. Olympia Tile products were used in the mudroom and powder room floors, a detail that speaks to the project's commitment to specifying rather than defaulting.
Plans and Drawings










The site plan reveals the house's relationship to the topography: a rectangular footprint oriented to maximize river views, with two smaller outbuildings positioned along the same axis. The ground floor plan shows an L-shaped layout that separates the sleeping wing from the communal spaces, while the upper and attic plans demonstrate how the program thins out vertically, from social density at grade to solitary study under the peak.
The longitudinal section is the drawing that explains the house most clearly. It traces the full height from garden-level dormitory to the oculus, showing how the double-height living room creates a vertical relationship between the mezzanine play area and the ground floor. The axonometric studies of the staircase and kitchen volumes are particularly revealing, illustrating how the curved balustrade negotiates the transition between the brick fireplace wall and the timber structure above.
Why This Project Matters
Le Grand Bercail succeeds because it treats the multigenerational brief not as a constraint to manage but as a spatial opportunity to design for. The house gives families reasons to be together (the festive heart, the gallery, the kitchen island) and places to be apart (the attic study, the bedroom suites, the garden-level dormitory) without ever making the boundary between the two feel rigid. The plan is legible, the hierarchy of spaces is clear, and the material palette unifies everything without flattening it.
Just as importantly, the project demonstrates that passive-design ambition and regional craft are not in tension. Hyper-insulated glazing, precise airtightness, and calibrated overhangs coexist with hand-shaped Douglas spruce balustrades, locally laid herringbone brick, and cedar from a regional supplier. In a moment when sustainability discourse too often splits into either high-tech gadgetry or nostalgic vernacular, Le Grand Bercail quietly occupies the space where both traditions overlap. That is the space where the best houses get built.
