Light lands first on the white curtains, then on the marble worktop below. The room reads open at once: a bright open home where the kitchen, living area, and dining space flow into one another, with large windows and roof windows pulling daylight deep into the extension. The old compartmentalized feel has been replaced by long sightlines, a calm palette, and a direct connection to the backyard.

A room plan built around daylight

The generous extension sets the tone for daily life. It brings the kitchen, living room, and dining area together in one open plan living kitchen, so movement stays easy and views stay wide. Glass surfaces do much of the work here. They soften the transition to the garden and make the interior feel measured by light rather than by walls. Even the ceiling lines stay quiet, with recessed spots and a clean finish that keeps attention on the room itself.

The round bay window remained in place, and that preserved curve gives the house a softer counterpoint to the long extension. Inside it, a round bay window seating arrangement with a custom bench and table fits the shape closely. The result is small in footprint but precise in effect. It offers a separate corner without breaking the open plan, and it draws the eye away from the straight kitchen runs for a moment.

Kitchen surfaces that do the framing

The kitchen is defined by contrast rather than decoration. Dark kitchen cabinetry sits against a marble worktop and matching backsplash, and the stone’s veining is visible across a wide surface. The darker wood on the rear wall adds depth, while the natural material on the countertop and wall gives the room a clear center. It is a custom kitchen marble composition that does not need much else; the materials already carry the composition.

That same back wall continues into the dining area as a built-in display cabinet, which ties the two spaces together without flattening them into one gesture. The cabinet gives the open plan a steady line to follow. It also keeps the kitchen from feeling isolated inside the extension. From the cooking zone, the view slips toward the dining table and then toward the living room, where the seating area waits in the same material rhythm.

Open plan living kitchen, kept visually calm

The open plan living kitchen works because each zone is distinct but not cut off. The kitchen handles the darker tones, the dining space holds the transition, and the living room opens toward the garden. Large windows and roof windows keep the daylight even across those shifts. In the images, the interior never turns heavy. Instead, the contrast between marble, wood, and painted walls gives the spaces a clear order.

Neat proportions matter here as much as materials. The ceiling reads high and uninterrupted, with long linear lights and minimal fixtures. That height gives the extension breathing room, especially around the dining and kitchen areas where the joinery runs low and horizontal. The room benefits from that restraint. There is enough texture in the stone and timber; the architecture does not need to compete with it.

The living room opens toward the garden

In the living room, the comfortable sofa sits opposite a modern fireplace wall with a dark outline and a travertine underside. The fireplace is not treated as a heavy centerpiece. Its clean surround and recessed wall niches keep it folded into the room. Nearby, the accessories stay understated, which lets the stone finish and the sharp lines of the wall read clearly. The space feels connected to the rest of the home rather than set apart from it.

That connection extends outside. The living room looks toward the backyard, and the windows turn that view into part of the interior composition. Birds and movement in the garden become visible from the seating area, so the room changes with what happens beyond the glass. This is where the bright open home feels most direct: not as an abstract concept, but as a room shaped by sightlines, window height, and the constant presence of daylight.

What the fireplace wall adds to the plan

The fireplace wall does more than anchor one corner. It gives the open living room a pause, a surface that settles the eye after the long run of windows and joinery. The travertine underside lightens the lower edge, while the darker frame defines the opening. Because the wall remains restrained, the sofa and side pieces can stay simple. The room keeps its focus on line, proportion, and the shift from interior to garden.

A preserved curve with its own scale

The original round bay window was kept, and it changes the tone of the whole house. Instead of another straight span, the curve gathers its own setting: a round bench and matching table fitted to the shape. That custom piece feels intimate without becoming ornamental. It also breaks up the geometry of the extension, which is otherwise long and rectilinear. In a house built around open movement, this is the one place where the plan briefly folds inward.

Upstairs, the sense of openness continues in a more private register. A large height marks the upper room, and beneath the window stands a freestanding bath placed almost like an object in a gallery. The same pairing appears again: natural stone and dark wood. Here, though, the materials frame quiet instead of conversation. The bath sits by the window, ready for light to move across its surface while the rest of the room stays spare.

Seen as a whole, the house relies on a few clear decisions: larger openings, a disciplined material palette, and custom elements that fit the plan closely. The bright open home is not built from excess. It is shaped by the way the kitchen leads into the living room, the way the bay window keeps its curve, and the way the garden stays in view from the main living spaces. That is what gives the interior its steady rhythm.
