1. Brief Audit Evidence (Supplied Facts): Wall & Constraints: 2.8 m (280 cm) wide wall, 2.45 m (245 cm) ceiling height. Thermostat located 35 cm from the right edge of the wall. Furniture: 1.9 m (190 cm) sofa positioned under the arrangement. Art Inventory (6 pieces total): 1× Indigo abstract print: 50 × 70 cm (portrait). 2× Charcoal line drawings: 30 × 40 cm (portrait). 3× Family photographs: 20 × 25 cm (2× portrait, 1× landscape). Style & Hardware: Calm asymmetric arrangement, walnut frames, 5–7 cm spacing between frames, removable hooks only (renter-friendly). Assumptions (Labeled & Conservative): Sofa Position: Assumed centered along the 280 cm wall (occupying x = 45 cm to x = 235 cm). Sofa Height & Seating Clearance: Assumed standard sofa back height of ~85 cm from floor, leaving ~160 cm vertical clearance above the sofa. Thermostat Position/Height: Located at x = 245 cm to x = 280 cm from the left corner, at standard switch height (~120–150 cm from floor). Frame Dimensions: Dimensions listed in the brief represent total outer frame dimensions including frames. Gaps & Conflicts: No structural contradictions detected in the supplied dimensions. Minor Gap: Exact vertical placement of the thermostat is unspecified, but its horizontal position (245–280 cm) keeps it outside our target layout footprint (which stays within the 190 cm sofa span, x = 45 cm to x = 235 cm). 2. Selected Collection Piece Dimensions Orientation Role Selection Reason Indigo Abstract 50 × 70 cm Portrait Anchor Strongest visual weight and largest scale; anchors the off-center focal point. Charcoal Line Drawing #1 30 × 40 cm Portrait Secondary Balances anchor mass across the vertical axis with soft graphic texture. Charcoal Line Drawing #2 30 × 40 cm Portrait Secondary Provides vertical symmetry on the opposing side to create rhythm. Family Photo #1 20 × 25 cm Portrait Bridge Connects the anchor to secondary pieces; distributes photography medium. Family Photo #2 20 × 25 cm Portrait Bridge Fills intermediate cluster void and ties smaller scales together. Family Photo #3 20 × 25 cm Landscape Accent Adds dynamic variation in orientation; acts as a visual counterweight. Exclusions: None. All 6 pieces are used to form a balanced, cohesive, 6-piece gallery layout. 3. Layout Options Layout A: Asymmetric Block Anchor (Left-Heavy Balance) Structure: Anchor (50×70) placed on the left side. The two 30×40 charcoals stack vertically on the right side. The three 20×25 family photos form a tight bridge column/cluster in the center-right transition zone. Overall Footprint: 140 cm Wide × 85 cm High. Spacing Logic: Strict 5 cm gap between adjacent frame edges. Ordered Positions (from Floor / Left Wall Edge): Position 1 (Anchor - Indigo): Bottom-Left | x: 50 cm to 100 cm | y: 140 cm to 210 cm Position 2 (Photo #1 - Portrait): Top-Middle | x: 105 cm to 125 cm | y: 185 cm to 210 cm Position 3 (Photo #3 - Landscape): Mid-Middle | x: 105 cm to 130 cm | y: 155 cm to 180 cm Position 4 (Photo #2 - Portrait): Bottom-Middle | x: 105 cm to 125 cm | y: 125 cm to 150 cm Position 5 (Charcoal #1): Top-Right | x: 135 cm to 165 cm | y: 170 cm to 210 cm Position 6 (Charcoal #2): Bottom-Right | x: 135 cm to 165 cm | y: 125 cm to 165 cm Strengths: Creates a clear narrative flow from rich indigo tone to light charcoal linework; very stable rectangular outer boundary. Risks: High visual density on the left side requires precise leveling so it doesn't feel lopsided. Layout B: Centered-Anchor Cloud Flow Structure: Indigo Abstract set in the center-left. Charcoals flank the top-left and bottom-right edges. Photos form a stepped diagonal path through the middle. Overall Footprint: 155 cm Wide × 95 cm High. Spacing Logic: Uniform 6 cm gap between all frame edges. Ordered Positions (from Floor / Left Wall Edge): Position 1 (Charcoal #1): Far-Left Top | x: 45 cm to 75 cm | y: 165 cm to 205 cm Position 2 (Indigo Abstract): Center-Left | x: 81 cm to 131 cm | y: 135 cm to 205 cm Position 3 (Photo #1 - Portrait): Top-Right | x: 137 cm to 157 cm | y: 180 cm to 205 cm Position 4 (Photo #3 - Landscape): Center-Right | x: 137 cm to 162 cm | y: 150 cm to 175 cm Position 5 (Photo #2 - Portrait): Far-Right Top | x: 168 cm to 188 cm | y: 175 cm to 200 cm Position 6 (Charcoal #2): Bottom-Right | x: 168 cm to 198 cm | y: 130 cm to 170 cm Strengths: Highly organic, relaxed aesthetic; spreads color tones evenly across the wall. Risks: Spans 155 cm wide, bringing right-hand pieces close to the thermostat zone; harder to align cleanly with removable hooks. 4. Recommendation Chosen Arrangement: Layout A (Asymmetric Block Anchor) Decision Rationale: Scale & Proportions: Layout A's footprint (140 cm wide) sits at 73.6% of the 190 cm sofa width—falling precisely into the ideal 66%–75% visual width rule for artwork above furniture. Clearance & Safety: Kept between x = 50 cm and x = 190 cm, staying well clear of the thermostat (starts at x = 245 cm). Bottom edge sits 40 cm above the sofa back, preventing accidental head bumps. Installation Feasibility: Straight vertical/horizontal alignment axes make hanging with removable adhesive hooks significantly easier and more accurate than a diagonal cloud layout. 5.

Top & Bottom Anchors: Hang Photo #1 (Piece 2) aligning its top edge flush with Piece 1 (at 210 cm). Hang Charcoal #2 (Piece 6) aligning its bottom edge flush with the baseline datum (125 cm). Secondary Vertical: Hang Charcoal #1 (Piece 5) flush to the top datum (210 cm) above Charcoal #2 with a 5 cm gap. Fill Center Column: Install Photo #2 (Piece 4) aligned to the bottom baseline (125 cm), then center Photo #3 (Piece 3) horizontally and vertically in the remaining middle slot with 5 cm gaps. 6. Shopping & Preparation List Frames: 6× Natural Walnut frames in specified artwork sizes (1× 50×70, 2× 30×40, 3× 20×25). Hardware (Damage-Free Renter Solution): 2× Medium/Large Sawtooth Picture Hanging Canvas Strips or Adhesive Wall Hooks (rated for frame weights, minimum 2.2 kg rating each). 8× Small/Medium Picture Hanging Adhesive Strips (for 30×40 and 20×25 frames).

Final QA Check [x] Alignment: Top flush line established at 210 cm (Indigo, Photo #1, Charcoal #1); bottom baseline established at 125 cm (Photo #2, Charcoal #2). [x] Sightline: Overall optical center sits at 162.5 cm—near standard standing eye level (~155–165 cm). [x] Color Balance: Strong indigo focal point balanced on left; lighter charcoal drawings visually counterweighted on right; warm walnut frames unify all 6 pieces. [x] Clearance: 40 cm safety margin above sofa back (85 cm + 40 cm = 125 cm art bottom); layout terminates at x = 165 cm, leaving 80 cm clearance from the thermostat at x = 245 cm. [x] Renter-Safety: 100% surface-safe installation using removable adhesive hooks/strips on painted drywall; zero drilling required.
