DIRECT ANSWER
Direct answer
AI-generated interior design renderings should begin from real spatial conditions: first organize the floor plan, dimensions, doors and windows, MEP provisions, retained elements, and client requirements; then select a base drawing, model, or photograph to control the layout; and handle style, materials, and lighting as separate concerns. The outputs are intended primarily for intent communication and scheme exploration. Any selected direction must be developed further through floor plans, elevations, detail drawings, material samples, and budget documentation, and must not be used directly as a basis for construction.
01 / APPLICABLE AUDIENCES
Applicable Scenarios
This workflow is suited to interior projects where a clear floor plan or on-site photographs are already available and the goal is to rapidly explore spatial character, material combinations, and presentation directions.
02 / STEPS
From Spatial Facts to Visual Expression
- Verify the floor plan against the site: confirm dimensions, doors and windows, beams and columns, MEP point locations, and all non-negotiable constraints.
- Establish spatial constraints: use a rough model, line drawing, depth map, or a mask with clearly defined boundaries to control composition — do not rely on text prompts alone.
- Isolate style variables: iterate separately on materials, color temperature, furniture, soft furnishings, and lighting.
- Lock confirmed content: fix all spatial conditions and design elements that have already been approved before each new generation round.
- Cross-check against the original conditions: verify scale, openings, furniture usability, and material logic.
- Feed selected images back into design files and sample-board lists for further development.

Begin by Establishing a Spatial-Facts Baseline Table
Before starting any generation, compile a baseline table recording room names, clear dimensions, floor-to-ceiling heights, doors and windows, beams and columns, MEP provisions, fixed joinery, retained elements, and any unknown conditions. When information in base drawings, photographs, and models conflicts, flag the conflict and return to the on-site source data for confirmation; do not allow AI-generated results to substitute for factual information.
Every round of candidate images must correspond to the same version of the baseline and to explicitly defined variables. If a candidate image has altered any fixed condition recorded in the baseline, that candidate must be discarded and regeneration must be based on the original spatial baseline. Only candidates that vary solely in materials, color temperature, furniture style, or lighting tendency should proceed to scheme comparison.

Preset Prompts Control Only the Direction of Expression
According to SketchUp's official documentation, the preset prompts in AI Render are used to control the visual style of generated outputs.
Whether construction information is complete must still be verified separately. This article recommends annotating each rendering with its intended use and version number, and linking it to the corresponding floor plan, material schedule, and budget records.

05 / BOUNDARIES
Manual Review Required
- AI may alter doors and windows, beams and columns, scale, and furniture structure.
- AI-generated materials do not necessarily correspond to real products, specifications, pricing, or availability.
- Lighting atmosphere is not equivalent to illuminance calculations or MEP design.
- Renderings cannot substitute for construction drawings, detail drawings, schedules, or on-site confirmation.

Returning Images to the Project Context
TechLab's publicly stated product direction emphasizes sharing project context. This article recommends that interior renderings not be treated as isolated images; instead, they should be recorded within the project workflow with their associated task, version, materials, and review comments. The specific method of recording should follow actual product capabilities and the team's established process.

FAQ / How to Create AI Interior Design Renderings: From Floor Plans and Shell-Condition Photographs to Scheme Visualization
Frequently Asked Questions
Can the process begin with only a single shell-condition photograph?
Early intent exploration is possible, but it must be made explicit that spatial conditions beyond what the photograph shows are unknown. The fewer floor-plan details, dimensions, and multi-angle views are available, the less suitable the results are for specific design decisions.
How can distortion of doors, windows, and furniture be reduced?
Use more precisely defined spatial base drawings, masks, or model constraints; reduce the range of variables changed in any single generation round; and after each round, check the output item by item against the original conditions.
Do AI renderings need to be annotated?
It is recommended to annotate each image as AI-generated or AI-assisted, and to record its version, intended use, and items still pending confirmation, so that clients or contractors do not mistake a conceptual visualization for an approved scheme.
