Check the drawings from your outside designers — with the article of law behind every finding.

WHO DOES WHAT

The software takes on the checking work.
People look only at the design judgement.

Recalculating figures, matching drawings against each other, applying the law, and keeping the record of the back-and-forth with your outside designers — the software takes these on. What designers look at is the design judgement.

Anything uncertain is marked “to be confirmed”; estimates are never reported as compliant. Final judgement is made by a licensed architect.

EDITABLE

What comes out, you can fix on the spot.

You do not have to send the software's findings as they are. Fix, drop or add them on screen — and make small drawing fixes without going back to your CAD.

Fix, exclude and add findings

• Click a finding's text, severity, grounds or location on screen and edit it in place.
• Exclude a finding you do not need; excluded findings never appear in the report.
• Right-click on the drawing to add a finding at that spot.
• Everything can be undone with Ctrl+Z. Edited findings are not overwritten by the software at the next submission.

Fix the drawing

• Small fixes to text, dimensions and lines use the same operations as Jw_cad (left = free point, right = snap point).
• Or open it in Jw_cad, fix and save there — it is reloaded automatically.
• The fixed drawing is re-checked as a new version. The original submission is never overwritten.

Version 1.0.0 (Japanese screens). All data is a fictional demo project.

LANGUAGES

Chinese and Vietnamese too. Your partners can check their own drawings before sending.

Many builders outsource drafting to design offices in China and Vietnam. Besides checking on arrival in Japan, the drafting side can check against the same criteria before sending. The back-and-forth of findings and answers can be followed within the same project.

COMPARISON

How it differs from other tools

Insight Home Design focuses on checking received drawings, getting them fixed and keeping the record. Drawing, application calculations and on-site sharing are better done by other tools. Use it alongside the tools you already have.

◎ Strong　○ Supported　△ Partly / with conditions　— Not found in public information

Our assessment based on public information as of October 2026. These are general tendencies by type of tool and vary by product, version and configuration. A "—" for another tool means we found no mention in public information, not that the feature does not exist. The marks for Insight Home Design on receiving-side checks and mismatches between drawings describe the feature; how much checking time it saves is being measured in trials.

FLOOR PLAN DRAFTS (IN DEVELOPMENT)

Floor plan drafts: get a draft, then fix it on the drawing.

From the site survey drawing (.jww) and the conditions (law, product rules, surroundings), it makes draft floor plans. It first works out the height range the site allows — from the road slope, the north-side slope, the height district and the absolute height limit — and keeps the roof inside it; if nothing fits, the draft says so as “to be confirmed”. Designers finish them; the draft is a starting point for thinking.

• Drafts are labelled by colour: as requested / with a condition relaxed (the heading says which) / needs fixing before use.
• Drag walls and openings, double-click a room. Each change rebuilds the tatami counts, the area table and the checks on the spot. Ctrl+Z undoes.
• What was read as fact, what was assumed and what needs confirming are written on the drawing and in the check table.
• Draft checks include whether the roof (eaves and verges) stays inside the site. The road-slope setback is measured from whichever is closer to the road: the eaves or the tip of a second-floor balcony.
• On sites facing two or more roads, the area where a narrower road counts as having the wider road's width (Building Standards Act Enforcement Order art. 132(2)) is judged as the article states — in the drawing check as well.
• Export to PDF and Jw_cad (.jww) in one go. The .jww can go straight to your outside designer as the request drawing.
• Register your company's standard plans and the drafts follow your own patterns.

What comes out is a draft. Designers finish it, and final judgement is made by a licensed architect.Version 1.0.0 (Japanese screens). The site drawing is fictional.

FLOOR PLANS

Make floor plans for flyers and listing sites from your drawings, and adjust the look.

Since version 1.0.1, “Floor plans” is in the left menu. Real-estate agents and store sales staff can use it without going through the drawing check screens. Start from a blank sheet, an underlay, a plan drawing or a floor plan draft; adjust the look with styles, colors, floor patterns, tatami, parts and your logo; then export to images, PDF and more.

• Four ways to start: blank / trace an underlay (image, PDF, Jw_cad, DXF) / automatically from a plan drawing (Jw_cad, DXF, PDF) / from a floor plan draft
• Six looks (soft, simple, premium, monochrome, gray walls, hand-drawn); per-room colors and floor patterns; tatami layout for Japanese-style rooms
• Room names, jō counts, floor and total areas and the north arrow are filled in automatically; add notes, your company name and logo
• 61 parts (kitchen, bath, furniture, cars, plants and more); add your company's own parts and default colors
• Export to PNG, JPEG, BMP, GIF, TIFF, PDF, SVG and EPS; high resolution (4K/8K) and to-scale printing (1/50, 1/100, 1/200)
• Before export, a side panel shows guideline checks for Japanese real-estate ads (jō count at 1.62 m² per jō, how to label rooms without windows). They are guides for you to confirm, and nothing is drawn on the plan

WHAT YOU DECIDE

What you decide.

What the law decides, the product carries. Your own design standards are yours to set, and the product checks against them. Design judgement stays with the designer, as it always has.

How to decide them is in the onboarding guide (PDF). It runs on the standard values at first, so you can decide after the trial. Open the onboarding guide
