A split-level penthouse lounge built around a tufted cognac leather modular sofa, layered with a smoked-glass sculptural table, a maze-carved cream rug, black-gold marble surfaces and LED-washed timber slats, all open to a planted terrace through full-height glazing.
The idea behind it
The room runs on material contrast with a single warm hero. Cognac leather supplies nearly all the colour, while stone, smoked glass and dark timber form a cool, architectural shell — so the sofa reads as the heart of the space rather than one item among many.
Zoning is done with layers, not walls: the carved geometric rug defines the lounge, a smoked-glass balustrade and three marble steps lift the dining platform behind it, and a pendant cluster marks the table. Each zone borrows light and views from the others.
Integrated lighting is the quiet luxury. LED lines washing the slatted wall, edge-lit shelving and the linear fireplace mean the room glows from its architecture at night, with the black-gold marble catching every flicker.

Steal the look
Step 1
Lay the oversized cream geometric rug first and centre the lounge on it, clear of circulation paths.
Step 2
Build the L with leather modules facing the fireplace and view; float the ottoman to keep the layout loose.
Step 3
Centre the smoked-glass table on the rug and style it with a tray, a bowl and one book stack.
Step 4
Clad the fireplace wall in black-gold marble (or quality porcelain slab) around a linear firebox.
Step 5
Fit vertical timber slats on the rear wall with warm LED strips behind or between battens.
Step 6
Edge-light the shelving bay and dim everything to the same warm temperature, about 2700K.
Step 7
Hang a cluster of slim brass pendants over the dining table on the raised level.
Step 8
Finish with a tall potted tree near the glazing and echo the greenery outside on the terrace.
Perfect for
- Open-plan apartments with big glazing and city views
- Fans of warm, masculine modern-luxury interiors
- Households wanting durable seating — leather ages better than fabric
- Entertainers who need lounge and dining zones to flow together
Avoid if
- Your room is small — the modular scale and level changes need space
- You prefer light, airy Scandinavian schemes over dark stone
- Integrated LED and marble cladding exceed the renovation budget
- Strong sun hits the seating daily; leather fades without UV protection

Frequently AskedQuestions
Cognac thrives against architectural neutrals: cream and greige stone, smoked glass, dark timber and black marble with gold veining. Keep other upholstery muted — an olive or taupe accent chair works — and repeat warm metallics like brass in lighting so the leather's tone feels deliberate rather than isolated.
Anchor it with an oversized rug — ideally patterned or carved so its border reads clearly — and arrange the sofa in an L that turns its back to circulation routes. A level change, a balustrade or even a cluster of pendants over the adjacent zone reinforces the boundary without walls.
Smoked glass is more forgiving than clear — fingerprints and dust show far less on a bronze or brown tint. Choose a thick, rounded-edge sculptural base rather than thin legs for stability, and its transparency keeps a large seating group from feeling crowded.
