How it works

Five steps. AI does the heavy drafting; a registered architect reviews and signs. You stay in control at every step.

  1. Brief

    Fill out a structured form in 10 minutes: plot, building, preferences, photos.

    ≈10 min · client

  2. AI working draft

    Our system produces a code-compliant concept within 24 hours.

    ≤24 h · automated

  3. Engineer review

    Our internal engineer checks the draft, fixes obvious issues and queues it for the architect.

    ≈4 h · in-house

  4. Architect sign-off

    A registered local architect reviews, refines and signs the document.

    ≤2 days · partner

  5. Hand-over

    You receive the signed PDF, source files and a code-citation checklist.

Four phases · who does what · how long

An explicit AI/human split with time estimates. No claims are made until a registered architect signs the deliverable.

  1. Brief intake

    You describe the plot, the building and your priorities.

    ≈10–15 minclient

    AI does

    • Validate the structured form against the schema in real time.
    • Suggest sensible defaults from the selected jurisdiction (building code, units, energy targets).

    Humans do

    • You fill out the form yourself; no architect is involved at this stage.
    • You can save and return — no payment is taken before the working draft is shown.
  2. AI working draft

    Automated generation of a structured first draft.

    ≤24 hClaude Opus 4.7

    AI does

    • Generate the requested sections (executive summary, area breakdown, code-compliance notes, indicative energy and cost ranges).
    • Cite the relevant clauses of the local building code in every section.
    • Run an internal validation pass against the output schema and the forbidden-phrases list.

    Humans do

    • Nothing in this phase — the output is flagged as a draft.
    • The draft is stored internally and never sent to any authority, lender or insurer.

    Working draftthis output is a working draft only — not project documentation, not legally binding, never submitted to a competent authority.

  3. Engineer review

    An in-house engineer reads the AI output and corrects it.

    1–3 business daysengineer · in-house

    AI does

    • Surface schema-validation issues and forbidden-phrase matches to the engineer.
    • No new content is generated in this phase.

    Humans do

    • The engineer cross-checks every numeric claim against the source code.
    • Unclear or speculative passages are rewritten or removed.
    • If the case is out of scope (heritage, complex structure, non-standard plot) the engineer escalates or refuses.
  4. Architect sign-off

    A registered partner architect reviews and either signs or rejects.

    1–2 business daysregistered architect

    AI does

    • Nothing — the architect makes the decision on their professional responsibility.
    • The system logs the architect's name, registration number and date of signature.

    Humans do

    • The partner architect verifies plot-specific feasibility on site or from documents.
    • The architect signs the deliverable under their registration — at this moment the document becomes project documentation.
    • If the architect refuses, you receive written revision notes and a full refund of the architect-fee portion.

    Tier 2 / Tier 3Phase 4 applies only to Tier 2 and Tier 3. Tier 0 and Tier 1 outputs remain advisory after engineer review and are clearly marked as such.

Tier 0 and Tier 1 deliverables stop at phase 3 (engineer-reviewed advisory output). Only Tier 2 and Tier 3 include phase 4 — sign-off by a partner architect registered with the local register. The AI draft is never submitted to any authority.

AI narrative
Site context
AI confidence: 86%

The 320 m² plot sits in a semi-urban Almere block with predominantly two-storey detached neighbours. The southern setback (3 m) and the protected oak on the north boundary anchor the building footprint to the central two-thirds of the plot. The dwelling is positioned to keep the oak's drip-line uncompromised and to capture south-west afternoon light into the main living volume.

Volumetric concept
AI confidence: 81%

A compact two-storey volume with a low-pitch (10°) saddle roof, optimised for a south-facing PV array. Ground floor: open kitchen-living-dining (≈42 m²), home office (≈10 m²), entrance hall, WC and technical room. Upper floor: master suite with en-suite (≈22 m²), three further bedrooms (10–14 m² each), shared bathroom. The footprint stays within the standard NL plot-coverage ratio (Bouwbesluit / local bestemmingsplan to be confirmed).

Energy strategy
AI confidence: 78%

Envelope: Rc ≥ 4.7 m²·K/W (façade), Rc ≥ 6.3 m²·K/W (roof), triple-glazing U ≤ 1.0 W/m²·K. Air-tightness target qv;10 ≤ 0.4 dm³/(s·m²). Air-source heat pump (≈8 kW nominal) feeding low-temperature underfloor heating; balanced MV-HR with ≥ 92 % heat-recovery efficiency. Roof prepared for ≈ 4.0 kWp PV. Indicative BENG-1: ≤ 55 kWh/m²·year — to be verified by formal BENG calculation in Tier 1+.

Permit-package scope
AI confidence: 74%

For a Dutch new-build of this scale the omgevingsvergunning (Omgevingswet, in force since 1 Jan 2024) typically bundles the activities Bouwen, Slopen and (where applicable) Kappen. The drawing set below is the minimum the municipality of Almere expects for the bouwen-component; the cost schedule and construction timeline are advisory at Tier 0 and become binding only once an SBA-registered architect signs the Tier 2 package.

Open data gaps

Confidence is constrained by two open data gaps: the local bestemmingsplan has not been pulled, and there is no soil survey (sondering) yet. Both are required before any number on this page is treated as binding.

  • Local bestemmingsplan / Omgevingsplan rules for the specific cadastral parcel.
  • Soil survey (sondering) — needed to confirm foundation type and pile depth.
  • Confirmed DB-Geo / archaeological screening for the immediate plot.
  • Verified PV / heat-pump supplier quotes for the cost band.

SampleSample output. The figures, layouts and code references on this page are illustrative — they describe a fictional commission for an imagined family in Almere and are not advice for any specific plot. A real Tier 0 brief is generated from your own inputs and is reviewed by an in-house engineer before you ever see a number we treat as binding. Project documentation in the legal sense is only produced once an SBA-registered architect signs at Tier 2.

What AI does · what humans do

We are explicit about the AI/human split — it's a regulatory requirement and a question of trust.

Done by AI

  • Executive summary and area breakdown
  • Drafting compliance checks against the local building code
  • Drafting energy-performance estimates
  • Cost-range and material estimate (informational)

Done by humans

  • Engineer cross-checks the AI output
  • Architect verifies plot-specific feasibility
  • Architect signs the deliverable on their registration
  • DPO handles GDPR requests within 30 days
