Layout plans
Explore in 1-2 hours multiple space layout options to validate the best path before detailed rendering.
Space layout (partitions, furniture, circulations) is an optimization exercise where multiple paths must be tested before finding the best. AI lets you quickly ideate multiple scenarios, architect refines after. Combined with tools like Midjourney to visualize, client can quickly validate direction. This guide presents the workflow that multiplies project-start iterations.
Step-by-step workflow
Characterize existing space
Existing plans with dimensions, ceiling heights, openings, ducts, water points, electrical outlets, constraints. Without precision, AI invents non-existent constraints.
Define program
Functions to integrate: zones (living, dining, sleeping, working), capacities, essential equipment. Guides layout choices.
Have 3-5 options generated
Request TRULY distinct layouts: open-space vs partitioning, central vs peripheral, traditional vs innovative. Useful comparison for client.
Visualize with Midjourney
For each retained option: 1-2 ambiance images via Midjourney. Lets client visualize without yet investing in 3D rendering.
Decide and deepen
Client chooses. Architect switches to SketchUp/AutoCAD for precise plan, and photorealistic 3D for final validation. AI saved initial ideation hours.

5 layout options
You're a senior interior architect. For this space: **Total surface**: [SQM] **Configuration**: [SPATIAL DESCRIPTION] **Openings**: [LIST] **Technical constraints**: [STRUCTURAL, DUCTS, FIXED WATER POINTS] **Ceiling height**: [HEIGHT] **Program**: [FUNCTIONS TO INTEGRATE] **Lifestyle**: [FAMILY DESCRIPTION] Propose 5 TRULY distinct layout options: 1. **Option A — Open space**: maximum decompartmentalization 2. **Option B — Semi-partitioned**: defined zones but visually connected 3. **Option C — Traditional partitioning**: closed rooms 4. **Option D — Biophilic**: nature integration, vegetation, natural light 5. **Option E — Modular**: mobile partitions, multifunction rooms For each: concept in 3 lines, zone implantation, strengths, weaknesses, which lifestyle works best, estimated budget.
Circulation optimization
For this layout: [RETAINED OPTION DESCRIPTION] Analyze circulations: 1. **Main flows**: daily trajectories 2. **Conflicts**: zones where flows cross 3. **Minimum widths**: compliance (corridors, door clearances) 4. **Buffer zones**: entry, transition spaces 5. **Optimizations** to fluidify Produce flow schema with improvements.

Frequently asked questions
Can AI draw precise plans?
For conceptual sketches and ideation: yes (textual or via Midjourney). For technical execution drawings: no, AutoCAD/SketchUp/ArchiCAD remain essential. AI helps explore, architect builds.
How to communicate multiple options to client?
Winning format: for each option, 1 schematic plan + 1 Midjourney ambiance image + 1 explanation paragraph. Client sees, understands, chooses in 30 minutes. That changes validation speed.
Risk of inventing non-existent constraints?
Real if constraints aren't specified. AI can assume a load-bearing wall where there isn't one, or invert. Always provide exact existing plan. For precise surveys, some apps (Magicplan, Polycam) digitize quickly.
What relationship between AI and SketchUp/Revit?
Complementary: AI for ideation and client communication, SketchUp/Revit for detailed rendering and execution. Emerging in 2026: AI plugins in SketchUp and Revit to generate variants directly.
