AI for Site Feasibility & Development Planning

BUILDPLAN

Turn a site into a buildable business case.

BUILDPLAN guides the real planning workflow: set up the site, generate massing, test feasibility, build a BOQ, generate design images, and export a shareable proposal from one web app.

Built for developers, planning teams, land owners, and early-stage investment review.

How BUILDPLAN works

Workflow reflects the current product experience. Times vary by project.

Typical early-stage process

Fragmented workflow
1
Gather site facts in separate toolsStep 1

Map lookup, site area checks, and legal assumptions are scattered.

2
Test a building option manuallyStep 2

Volume studies, floor assumptions, and revisions take repeated effort.

3
Build the financial case in spreadsheetsStep 3

Rent, cost, loan, and return assumptions are hard to compare quickly.

4
Prepare something stakeholders can reviewStep 4

Sharing often means reformatting slides or PDFs from scratch.

Inside BUILDPLAN

One connected flow
1
Set the siteSite

Search an address, draw boundaries, and capture area/perimeter on the map.

2
Generate massingMassing

Test structure, floors, unit mix, and regulation-aware building volume.

3
Run feasibilityFinancial

Review cost, NOI, Cap Rate, IRR, NPV, DSCR, charts, and scenario assumptions.

4
Package and shareOutput

Use AI assistant, generate design images, export BOQ and PDF, or send a share link.

What teams get faster

Illustrative summary based on the current BUILDPLAN workflow.

Faster

Decision speed

Less switching between maps, spreadsheets, and slide decks

Lower

Rework

Site, massing, and financial assumptions stay connected

Stronger

Review readiness

Export a proposal or share a read-only link when the scenario is ready

Current product workflow

1

Site setup on map

Start from address, boundary, and site metrics

  • Search the address and center the project on Google Maps 3D
  • Draw the site boundary directly on the map
  • Auto-calculate site area and perimeter in real time
  • Switch country and language settings, including Japan and Mongolia
2

Massing and regulation-aware planning

Build a practical volume study before detailed design

  • Set building use (residential, office, retail, mixed), structure, and floor count
  • Automatic compliance checks for coverage ratio, FAR, and height limits
  • Violations are listed together with suggested fixes
  • Visualize constraints such as Japan's slant-plane rules in 3D
3

Feasibility engine

Move from geometry to returns in the same project

  • Review cost, income, and annual report outputs in one place
  • Adjust financing such as LTV, loan rate, and term with multi-year amortization
  • Track NOI, Cap Rate, IRR, NPV, DSCR, and payback period
  • Compare rental vs. sale scenarios and save plan variants
4

BOQ β€” Bill of Quantities

From geometry straight to a cost breakdown

  • Auto-generate a multi-line BOQ from building type and size
  • Add, edit, and group line items by category
  • Save snapshots and compare two versions side by side
  • Export to CSV and PDF β€” with localized templates and currencies
5

AI, design, and delivery

Prepare a stakeholder-ready output without rebuilding the story

  • The AI assistant guides each step using your project data
  • Generate exterior design images from 4 angles based on materials and style
  • Export a PDF proposal after financial review
  • Share time-limited read-only links and track view counts

Who uses it

Developers & planning teams

β€œWe can move from site review to an internal go/no-go discussion in one flow.”

β€” BUILDPLAN use case

  • Land review before acquisition
  • Option studies before architect handoff
  • Internal investment committee materials

Land owners & investors

β€œIt is easier to compare what can realistically be built before committing.”

β€” BUILDPLAN use case

  • Second opinion on proposals
  • Sell vs. develop comparison
  • Early investment screening

Construction, finance & partner teams

  • Shared feasibility review
  • Loan and return discussions
  • Read-only sharing with partners and stakeholders

Frequently Asked Questions

What does BUILDPLAN actually cover?

BUILDPLAN covers the early planning flow: project setup, site boundary definition, massing, regulation checks, feasibility analysis, BOQ, AI assistance, design image generation, share links, and PDF export.

Do I need CAD or BIM expertise to start?

No. The AI assistant starts from an address and guides you through each required input step by step.

Which financial indicators can I review?

NOI, Cap Rate, IRR, NPV, DSCR, payback period, annual income/expense reports, and loan amortization schedules β€” all recalculated as assumptions change.

Which languages and countries are supported?

The interface is available in Mongolian, Japanese, English, and Korean. Japan-specific zoning math (coverage, FAR, slant planes) and Mongolian market settings (MNT currency, regional pricing) are built in.

How is project access handled?

Projects are tied to the authenticated user account. External sharing uses time-limited read-only links with view tracking.

Can I export something client-ready?

Yes. Export a PDF proposal after financial review, and include AI-generated design images and the BOQ breakdown if needed.

Planned expansion

Phase 2

BIM and floor logic

  • More advanced massing generation
  • Better floor/unit optimization
  • Clearer 3D constraint visualization
Phase 3

Market and cost data depth

  • Broader rent and cost references
  • Stronger benchmarking inputs
  • Improved scenario confidence for planning decisions
Phase 4

Document intelligence

  • Reading land and planning documents
  • Constraint extraction from source files
  • Natural-language instructions for planning tasks
