Prompt:

Architectural interior rendering of the main stair and an adjacent 84" door at the lower stair hall — a single composition that captures both of LDD-19's design moves. The viewer stands at the foot of the stair looking diagonally up so the full ascending run is legible, with a typical 84" flat solid-core door visible at frame-right opening onto an adjacent room. Photoreal still, 16:9 aspect, captured in calm even daylight. No people in frame.

Spatial framing. The 54"-wide open main stair runs diagonally up from frame-left lower foreground to frame-center middle distance. The composition emphasizes the stair's generous width — there is visible space to either side of where two people could comfortably pass. At frame-right, a typical 84" tall flat solid-core door stands in a continuous medium-warm-gray wall plane, slightly ajar to read its full height against the room beyond.

The stair detail (left and center of frame).
- Generous width. 54" between the wall side and the open guardrail side — wide enough that the stair reads as a major architectural element, NOT a utility run.
- Comfortable proportions. 21 risers, ~6.85" rise, 11" tread depth. The treads are deep enough to read as easy and inviting; the rise is shallow enough to feel relaxed.
- Tread + riser material. Solid white-oak treads with a natural matte finish (no gloss). Closed risers in matte medium-warm-gray painted MDF, helping with acoustic isolation between floors. The white-oak treads have a clean 3/8" eased edge at the nosing — comfortable underfoot and disciplined visually.
- Open guardrail (right side of stair). Thin vertical 1/2" round matte dark-charcoal steel rods at code-compliant ~4" centers, capped by a warm white-oak top rail with a 3/8" eased edge. The rail continues up from the stair onto the upper-floor balustrade at the top of the run.
- Wall side handrail. A simple wall-mounted handrail in matte dark-charcoal steel with a continuous warm white-oak gripping top, mounted at code-compliant ~34" above tread nosing.
- Stair underside. Visible from the lower foreground — clean matte medium-warm-gray painted soffit with a recessed low-level navigation light at the bottom riser, casting a soft warm pool on the floor.

The door detail (right of frame).
- 84" tall flat solid-core slab door. Painted matte medium-warm-gray to match the wall plane, with a clean square edge profile (no panel inset, no detail molding). The door reads as a calm continuous extension of the wall when closed, and as a generous tall opening when open.
- Restrained hardware. A simple matte dark-bronze lever handle at 38" AFF and a discreet matching hinge set. NO ornate trim. NO oversized hardware. NO contrasting paint.
- Door frame. Minimal flat dark-bronze metal frame, ~3/4" reveal, no protruding casing.
- The 84" height payoff. With the door slightly ajar, the viewer can see the door's top edge is appreciably above standard 80" height — the proportion reads as quietly generous, NOT statement-monumental.

Floor. Wide-plank warm white-oak with subtle grain, matte natural finish, continuing under both the stair and the door threshold.

Wall planes. Medium warm-gray painted drywall, with a faint concealed cove glow at the wall/ceiling junction visible at the top of the frame.

Lighting mood. Calm even daylight from an off-frame upper window, raking gently down the stair treads and highlighting the white-oak grain. The 2700K cove glow adds a quiet warm horizontal datum. The low-level navigation light at the bottom riser adds a small warm pool. Mood is calm, generous, hand-friendly.

Material palette. Medium warm-gray walls and risers, warm white-oak treads / top rail / floor, matte dark-charcoal steel rods and wall handrail core, restrained dark-bronze door hardware and frame, warm dimmable 2700K LED accents.

What this is NOT (CRITICAL). Do NOT render as: a grand-staircase entry hall, a Hollywood-movie wide curving stair, a rustic-cabin stair with rough timber, an arts-and-crafts stair with heavy newel posts, a hotel-lobby monumental stair, a glass-and-cable suspension stair, or a contractor-grade utility stair. NO carpeted treads. NO oversized turned newel posts. NO ornate balusters. NO wrought-iron scrollwork. NO glass guard panels. NO cable rail (the project uses thin steel rods). NO open risers (closed risers per the acoustic spec). NO door panels with raised molding. NO craftsman-style door with stiles and rails. NO knob hardware (lever per the spec). NO contrasting "feature" paint on the door.

Style direction. Professional architectural visualization, photoreal, evenly exposed. Calm and quiet mood. Neutral camera at slight crouch eye-level (~4'-6") to capture the full stair run and the 84" door together. Wide angle equivalent to ~24mm full-frame. Sharp focus throughout, no shallow DOF. The render should feel like a single page of a contemporary residential-detail monograph — quietly proud of being well-proportioned and disciplined, never theatrical.
