Rosetta
French Second Empire in white limestone: a mansard with urns, an oculus in a cartouche, a rosette parterre
The client wanted a real French mansion — the kind that stands on the Avenue Foch behind wrought-iron gates, with a tall slate mansard and a white carved façade. We took the Second Empire — the grand Parisian style of Haussmann — and gathered it into a compact two-storey volume of white limestone. The main theme of the house is the circle. At the centre of the projection, under a segmental pediment, a round oculus is set in a carved cartouche; and below, on the same axis, a stone rosette of the parterre is laid in the court — the same circle, repeated underfoot. Between them, a double-height arched window with fan, circular glazing and a curved iron balcony; across the whole façade arched windows with the same fan glazing, like a jewel’s cut. The mansard is crowned by a filigree wrought-iron cresting and stone urn finials — a fine black-and-white silhouette against the sky. So Rosetta appeared: a French mansion that rhymes an oculus in the sky with a rosette underfoot.
Below is the path from idea to image to object: the façade and the mansard, the oculus and the entrance up close, the matter of the limestone, the rosette court and the garden, evening and winter.
White limestone under a slate mansard
The house is strictly symmetrical and built of white limestone. Above it rises a tall dark slate mansard of scaled tiling, which in the Parisian manner defines the silhouette and gives the house a whole living floor beneath the roof. Along the ridge runs a filigree wrought-iron cresting, and at the mansard corners stand stone urn finials — a fine black-and-white graphic against the sky. The central projection steps slightly forward and is crowned by a segmental pediment with a round oculus in a carved cartouche; to the sides, rounded corner bays. The ground and upper floors are tied by a ceremonial axis: above the arched entrance rises a double-height arched window with fan glazing and a curved iron balcony. Across the whole façade run tall arched windows with the same circular glazing and iron balconettes; the walls are articulated by rusticated lisenes and quoins, and above by a cornice with modillions and a carved frieze. The composition is ceremonial yet proportionate: the grand Parisian style taken at a compact scale.
The projection and the oculus
The oculus in the cartouche is the “eye” of the house at the centre of the pediment; it sets the circular theme that below will answer as the rosette of the parterre.
The bays and the glazing
The fan glazing is repeated in every window, like a cut: it catches the light and makes the white façade light, almost lace-like.
A fan window, an iron balcony and the round “eye” of the pediment
Up close the heart of the house opens — the central axis of the entrance. The arched doors with a fan transom are framed by a carved limestone portal with a cartouche keystone; above them, on carved brackets, projects a curved balcony with filigree wrought-iron railing, onto which opens a double-height arched window with fine fan, circular glazing. Higher still, in the segmental pediment of the mansard, a round oculus is set in a carved cartouche with a vegetal garland — the “eye” of the house, closing the vertical. To the sides of the entrance, cast-iron lanterns and tall arched windows with the same glazing. The white limestone here is a warm tone, smoothly dressed on the walls and deeply cut in the details: shell keystones, garlands, modillions. The black wrought steel of the balconies and lanterns sounds graphic against the white stone. This is a ceremonial entrance made as a piece of jewellery — and built exactly beneath the oculus, so that the gaze runs from below upward, from the threshold to the “eye” of the pediment.
The whole house rests on a single rhyme: a round oculus in the sky and a round rosette underfoot, and between them a fan window catching the light. This is the French school — when a detail above answers a detail below.
White limestone, slate and wrought-iron cresting
The house rests on three materials, calibrated to the purity of a Parisian façade. White limestone clads the whole volume: the smooth dressed walls, the rusticated lisenes and quoins, the window-frames, the carved cartouches and shell keystones, the frieze garlands, the cornice modillions, the urn finials. In the details it is cut deep — shadow in the scrolls of the cartouche and in the modillions makes the white stone alive; on the slabs a light natural patina is visible, which will only grow nobler with time. It is answered by the dark slate of the mansard — the deep graphite of the scaled roof, reading almost black against the pale stone. The third material is black wrought steel: the filigree cresting along the ridge, the curved central balcony, the window balconettes, the lanterns. Three tones — white stone, graphite slate, black ironwork — work as graphics: a pale volume, a dark roof, a fine black outline of cresting against the sky. We chose dense limestone, equally good in a smooth wall and in the fine carving of a cartouche, and natural slate that does not fade under the sun and snow near Moscow.
White limestone, dark slate and black ironwork — all of Paris in three materials. The luxury here is not in colour but in the purity of the contrast: pale carved stone, a graphite mansard and a fine black line of cresting against the sky.
The rosette parterre and the formal garden
The mansion stands behind a wrought-iron fence, and the court is resolved in the French manner, strictly on the central axis. Wrought-iron gates open the vista straight onto the entrance, and before the façade, exactly beneath the oculus of the pediment, a round stone rosette is laid in the court — a parterre of pale and dark stone with a circular pattern, rhyming the “eye” of the house underfoot. Around it, clipped bosquets, balls of box and gravel paths; all symmetrical and geometric, like the façade. The rear, garden façade is equally ceremonial: the same projection with its oculus and fan window opens onto a balustraded terrace with a double stair descending into a formal garden of roses, parterre and lawn. From above the whole idea is clear: the white volume under the slate mansard with cresting and urns, the rounded bays and — exactly on the axis of the entrance — the round rosette of the court, repeating the oculus. The top and the bottom of the house are rhymed by a single circle.
The gates and the rosette
The rosette of the court repeats the oculus of the pediment — the guest walks over a circle underfoot straight to the “eye” of the house above the entrance.
The garden façade
Both sides are symmetrical and crowned by a single oculus: the mansion is equally ceremonial to the court and to the garden.
At dusk the fan windows glow with gold
It is for the evening that this house was built around its windows. At dusk the tall arched windows with fan glazing ignite from within with warm gold, and the fine circular muntins read as glowing lace across the whole façade — the house becomes a row of golden fans. At the centre, brightest of all, glows the double-height window above the entrance; higher, in the segmental pediment, the round oculus fills with warm light — the “eye” of the house glows in the dusk. Concealed uplighting draws out the white limestone, the carving of the cartouches and the rusticated quoins, while the dark slate mansard with its wrought cresting dissolves into the blue sky — only the silhouette of the urns and the fine line of the cresting remain against the first stars. Below, in the court, the lit stone rosette repeats the glow of the oculus. In winter, with snow on the mansard, the cresting and the parterre, the picture is stricter and cleaner: the white stone merges with the snow, while the gold of the fan windows and the oculus glows especially clear. In every season Rosetta holds one thing — a French ceremony rhymed by a circle above and below.
Golden fans
In the evening the façade comes down to a row of glowing fans, and the oculus and the rosette echo each other in light, above and below.
Winter and the mansard
In winter the white stone vanishes in the snow — and all the brighter glow the gold of the fan windows and the “eye” of the oculus above the entrance.
Rosetta is about a house gathered on a single rhyme. An oculus in the sky and a rosette underfoot, fan windows and a slate mansard with wrought cresting — that is enough to make a mansion Parisian. A house like this can be built for you too — with an individual layout and siting on your own plot.
Next step
Want a mansion like this? Let’s discuss
We design French classicism of the full cycle: the Second Empire and neoclassicism, slate mansards with wrought-iron cresting, fine carving in limestone and formal parterres. A full cycle: architecture, hands-on construction supervision and a single hand — from the oculus in the cartouche to the stone rosette of the parterre.
