How it works
From a sentence to drawings for discussion. Six person-years of engineering underneath.
On the surface: the wizard and the editor - the same screens as in the app. Underneath run our own geometry kernel, a team of AI specialists, MEP in installation zones and a quality check from every view. Turn on the X-ray and look under the surface.
On the surfaceDescribe the building in your own words. The hologram beside the field follows what you type, and below it you see which parts of the brief the kit reads and what is still missing.
Under the surfaceThe server reads the brief and routes it: native building, kit, or the open lane. The turn then gets only the API vocabulary this building needs.
On the surfaceThe anatomy of a good brief: what is required, what is optional, examples and common mistakes - for a family house, a hospital, a hall, and a building no kit covers yet.
Under the surfaceEvery kit has its own guide: the order in which it reads a brief best, what each part controls in the kit, and what happens when a part is missing. A type without a kit is built in open mode.
On the surfaceThe summary shows the type, the architecture and the MEP. Choices the kit would otherwise make on its own - the layout, the storeys, the roof - are yours, one click each.
Under the surfaceThe answers are added to the brief of the turn, so the model and every further iteration work from the same words. Only options the kit builds cleanly are offered.
On the surfaceThe generation card shows what the AI team is doing right now. A family house usually takes 6–11 minutes.
Under the surfaceA team of AI specialists run by more than 23,000 lines of server orchestration, 49 tools of our own kernel, and a dedicated briefing for every turn.
On the surfaceSearch an address or a parcel. Harness loads the cadastre, aerial imagery and terrain, places the house on the plot and computes the earthworks. Official data in 10 countries: Czechia, Germany, Austria, Switzerland, Spain, the United Kingdom, Norway, the USA, Brazil and India.
Under the surfaceParcel boundaries from the cadastre (where the authorities publish it), elevation, the building line, setbacks and utility protection zones. The house turns to fit the plot, and levelling is counted apart from the foundation dig.
On the surface“Add a terrace with a pergola to the living room.” Or by hand in a full BIM editor - walls, windows, stairs, MEP, with undo and sections.
Under the surfaceOur own geometry and BIM kernel with more than 225,000 lines, not a layer over someone else’s CAD. An instruction becomes a measurable goal, and Harness offers another iteration until it is met.
On the surfaceA quality scan finds what does not fit and fixes it before you get the model.
Under the surfaceA gate of 11 aspects from every view, clash detection and rules of construction logic: nothing floating, stairs with headroom, rooms with air.
On the surfaceVisualization with sky and shadows right in the browser, plus a construction schedule and a bill of quantities generated from the model.
Under the surfaceThe schedule is assembled from the model’s elements by storey and phase; the quantities are counted by material and class and the model is coloured by them. No render farm needed.
On the surfaceA drawing set from the model with a checklist: fill in the authorised person and the plot, then download the PDF.
Under the surfaceDrawings are derived from the model, not drawn by hand: plans, sections, elevations, the site plan and MEP coordination drawings. The checklist shows what the set still lacks. It is not design documentation for a building permit.
On the surfaceA link for colleagues, 3D viewing without installing anything, or a client presentation in several styles. Export to IFC 4.3, DWG and DXF, PDF, XLSX and CSV, glTF and OBJ.
Under the surfaceThe presentation is a public page with the model, opened in the client’s browser. The model stays in your project and in open formats.
On the surfaceAn address, photos, drawings and a survey become a model of the existing state and a building passport.
Under the surfacePhotos are read question by question, compared with the cadastre and the terrain model, and the camera is registered to the photos.

The server reads the brief and routes it: native building, kit, or the open lane. The turn then gets only the API vocabulary this building needs.
These are not images or finished files. The editor assembles each one in your own browser, element by element, and then you turn it round.
Live model - BIM Harness
The model is assembled on your own machine, not on our server. It takes a few seconds depending on the building.
Example models

Linear structures: from terrain to drawings
Roads and railways in one workflow from the brief to the drawings. You describe the project in one sentence; the app downloads DMR 5G terrain and orthophoto from ČÚZK and proposes route variants. Alignment, vertical profile, cross-section with superelevation, earthworks, nearby utilities and a station with its platform are computed over the same terrain in S-JTSK coordinates and saved into one BIM model, which produces the drawings, setting-out, a bill of quantities in OTSKP items and SFDI data.
Where: design categories and standards for Czechia (ČSN 73 6101, TP 170) and Germany (RAL, RAA). DMR 5G terrain is fetched from ČÚZK inside the app; elsewhere the design runs on your own survey (LandXML TIN, DWG).

01
Brief and ČÚZK data
The project described in one sentence; the app fetches DMR 5G terrain and orthophoto from ČÚZK for a corridor around the route.
02
S-JTSK coordinates
Main points of the route in Y, X with the bearing, the way Czech designers read them on a map; one click switches to E, N for CAD.
03
Route variants
The app proposes several routes over the terrain and compares length, earthworks, land take and cost; take the chosen one with one click.
04
Cross-section to TP 170
Category S 7.5 with the pavement layers, verges, slopes and ditches; superelevation in a curve is the same in the section, in 3D and on the drawings.
05
Earthworks and mass haul
Cut, fill, topsoil and the mass balance along the whole route, including what goes to the spoil heap.
06
3D road body
Saved to BIM, the road with its embankments, cuttings, ditches and guardrails sits in one 3D model over the terrain.
07
Nearby utilities
Crossings with existing utilities with cover and protection zones; for clashes the app proposes a sleeve or a relocation.
08
Railway
A single-track line with ballast, concrete sleepers and overhead line, with the same section and 3D as the road.
09
Station and platform
A station drawn as an area: building, platform, parking, turning loop and greenery; items can be moved by hand and stay with the route.
10
Drawings and handover
A sheet list with title blocks, PDF and DXF, setting-out points in S-JTSK, an OTSKP bill of quantities and versions in the CDE.
Coming soon · alphaAlpha means the whole path from survey data to drawings already works in the app and is being tested on real surveys, but layer thicknesses, clearances and tunnel excavation classes are still practice-based estimates (the standards are being added), bridge reinforcement is a first draft without structural analysis, and the SFDI and OTSKP outputs have not yet been checked by a designer.
Not a shell. A building with fourteen MEP systems.
Massing generators stop at the envelope and the layout. Harness carries on where a designer’s real work starts - services, penetrations and coordination.
Architecture and layout
Storeys, rooms by typology, circulation cores, multi-storey atria with escalators, set-back storeys, cantilevers and organic forms.
Structure and reinforcement
Columns on grids, beams, slabs, precast elements and steel halls. Foundations that follow the terrain and reinforcement generated to EN 1992 (Eurocode 2) rules - with schedules and drawings.
Ventilation, water and heating
HVAC with heat recovery, chilled water, heating from boiler cascades to radiators, domestic water with circulation and drainage laid to falls - mains in the ceiling void, shafts, risers and penetrations cut into the structure.
Electrics down to the circuits
Service connection, switchroom, boards per floor, feeders sized for the load, circuits, cable trays, emergency lighting, lightning protection with earthing and EV charging.
Low-voltage, fire and gases
Data cabling kept apart from power, fire alarm, sprinklers, gas and medical gases routed all the way to the beds.
MEP with clash checking
Clashes are not hunted down after handover. The check runs inside generation and measures analytically - route axes, radii, containment in a solid - and automatic repair reroutes the services until the model has no hard clashes.
A large hospital model now carries more than 4,000 MEP components across fourteen systems - and leaves without hard clashes. Every release is guarded by a regression suite of 4,500+ tests and a benchmark of 21 reference buildings, from a bungalow to a hospital wing with medical gases; live runs on real briefs keep stress-testing the whole chain.

Once a generation
Design has changed like this only twice. This is the third time.
From ink and ruler to the cursor took thirty years. From the cursor to a single sentence took one leap.
1960
Drawing board
Every line by hand, in ink, against a ruler. A changed brief meant redrawing the sheet from scratch — and every trade with it.

BIM Harness
Describe a building in one sentence and AI builds it: structure, rooms, façade and 14 MEP systems with clash checking. Open IFC you keep editing.
minutesfrom sentence to building
Those who moved from the board to CAD first gained years of lead.
That moment is here again.
An AI that doesn’t draw pictures. It builds models.
There are hundreds of image generators. BIM Harness is the only tool we know of that returns a complete, still-editable BIM model from a description.

Under the hood
Our own kernel, not a layer on someone else’s CAD
Most AI tools for architecture are plugins for established, expensive software - and they inherit both their ceiling and their licence. BIM Harness stands on a parametric kernel we wrote from scratch. That is precisely why it can do what a wrapper cannot reach.
The kernel is a parametric model in the browser - not IFC in memory. Move a wall and only what hangs on it regenerates; that is why an edit is instant, and a whole hospital of roughly 20,000 elements, MEP included, builds on the kernel in under a minute. Rendering runs on streamed 3D tiles, so even a model of 86,000 elements turns smoothly in the browser. IFC is the entrance and the exit.

A parametric object model
A wall knows it is a wall: it has a build-up, mitred corners, openings as a relation and a dependency graph. Change the type and the model regenerates - no rewriting lines in a file and hoping.
Grids, families, types and formulas
Structural grids, columns on intersections, datum elements, families with parameters and unit-checked formulas. Exactly the layer desktop BIM tools stand on - in the browser, without a five-figure licence.
Views, drawings and schedules
Plans and sections are generated from the geometry, annotations belong to the view, and schedules work both ways: overwrite a number in the table and the model changes.
IFC is the boundary, not the internals
The model does not live as STEP lines in memory. IFC is imported at the entrance and generated deterministically at the exit - which is why the export never collapses into triangle soup.

Harness builds more than houses now
Your own kits from one sentence, architectural style as data, spaces before walls, building services the way a designer draws them, and the passport of an existing building. The numbers come from live runs, not slides.

01Kits
Your own kit from one sentence
Write "Create a kit for breweries: brewhouse, fermentation, bottling…". Harness researches the parts, writes them as parametric functions, builds a demo and saves the kit for your organization. The next project simply uses it.
Industrial kits stand on a verified base: halls with structure, roof lights and PV, cranes, robots, racks, vehicles and the site
Every "Improve the kit…" turn files its next version
A factory from the kit for 2.2 credits in 97 seconds
Verified live on 4 Oct: a car plant, a brewery, a gondola lift and a playground. Each kit came from one sentence for 3 to 16 credits.
32 built-in styles from classical to parametric, or your own style card from photos, words or a model. Every later model keeps to it and reports after the build how many of its rules it met.
Massing, proportions, bay rhythm, openings, roof and materials by zone
Make the card by hand or with AI, most often from photos
Verified by a trial build of a sample house, at no credit cost
A style is data, not code: you create it yourself, without a programmer and without approval.
The building programme, operational links and standard room sizes are planned first. With them comes the room for services: shafts, ceiling voids, pre-walls and the installation zones of walls.
Rooms by typology and operational links
Shafts and service spaces reserved up front, not squeezed in later
The holographic preview changes with every choice
When a trade does not fit, its space grows by rule: a lower ceiling, a wider pre-wall. Nothing is left out.
04Building servicesIn verification
Services the way a designer draws them: zones, not blind routing
Electrical only in the installation zones of walls per ČSN 33 2130, water and heating in the floor build-up and pre-walls, drainage in shafts and under the slab, ventilation in the ceiling void, and every trade in its own lane. No two trades get the same place, so they cannot clash.
A trade is a data record: zones, lane, terminals, topology and sizing
Generator and checker use the same standard rule
Five building-services trades, domain networks for infrastructure
The zone engine is being verified on a corpus of houses and villas, then on a care home, a hotel and a hall.
Zones are derived from the architecture, so a changed layout means a new computation of zones and routes, not manual redrawing. No clash hunting and patching: every trade has its place from the start.
A zone grows monotonically and deterministically; nothing is ever left out
A new trade is added as data only; the engine does not change
Large buildings are coordinated by a typical section, as in hospitals and airports
The same principle will carry halls and stadiums: a band in the trusses, a service gallery, risers in the cores.
06Passport
Existing buildings: a model and a passport from photos and drawings
An address, facade photos, old drawings and a survey become a model of the existing state and a building passport. The AI only reads, deterministic code measures, and a person confirms the facts.
Drawings are read tile by tile, rectified, and the scale is calibrated by the areas in the legend
Facade photos settle openings, plinth, roof and colours
Checked against the cadastre and the DMR 5G terrain model
Every fact in the model cites its source
Interiors only for documented storeys, windows as whole frames without drift, nothing invented.
07Sport and infrastructure
Stadiums, roads and ports from kits
Verified kits for works that are not buildings: a football stadium and an ice-hockey arena, a cloverleaf interchange and a road through hills, a container terminal with cranes and a ship.
Roads the way a road designer draws them: transition curves, vertical curves, pavement layers on a 1:1 edge, shoulders, slopes with topsoil
Guardrails, delineators, kilometre posts, markings and lighting
Stadiums with a bowl of stands, a roof, floodlights and entrances
Open every model in the gallery, live in your browser.
Harness is not a walled garden. It opens IFC from Autodesk and Civil 3D, exports IFC4X3, writes properties to the Czech building data standard and hands you drawings as PDF and DWG.
IFC import with no silent loss
Every entity type in the schema has a declared fate and every element shows up in the import report. Across real-world exports from Autodesk 2021–2024 to Civil 3D - IFC2X3, IFC4 and IFC4X3, alignments included - measured import coverage is 1.0. What doesn’t import, you know about; nothing vanishes without a trace.
Building data standard
Properties are written as typed IFC values, the model validates against IDS, and the vocabulary of the Czech data standard (ČAS) loads straight from the public API. CCI classification lives in the project as maintained data, not as a note.
Drawings, PDF and exchanges
Plans and sections are generated from the model geometry and exported to PDF - dimensions, annotations and full diacritics included. The schedule exchanges with MS Project, the take-off with Excel.

Generative design has a reputation for grey blocks. BIM Harness builds real geometry - classical ornament as well as modern forms - and shows it photorealistically right in the editor.
Modern architecture
Rounded and organic forms, cantilevers, set-back storeys, glazed ground floors as lightweight curtain walls, timber cladding and multi-storey atria with escalators. From one sentence: a villa, a shopping centre, a hotel or a cultural centre.
Ornament as geometry
Cornices, window surrounds, corner rustication, pilasters, balustrades, arches, gables and dentils. Shaped profiles swept along the perimeter that break at openings and regenerate when you edit.
Photorealism without a render farm
Photographed PBR materials, shader-drawn timber, transparent glass, a sky with a sun and filmic tone mapping. Path tracing right in the browser produces photorealistic stills and fly-throughs - with no export to another program.
Built on the real terrain
Terrain from the Czech elevation model (DMR 5G), footprints from the Czech cadastre (RÚIAN) and photographs as the benchmark for fidelity. That is why the castles in the gallery sit on their rock - and your house sits on its plot.
AI design is just the start. Underneath sits a full BIM editor.
AI design of a whole building
A written description becomes a complete model: layout, structure, openings, façade, roof and fourteen MEP systems - from a family house to a hospital of 23,000 elements.
A team of 30 AI specialists
It is not one prompt working on the model. A registry of 30 roles - from structure and HVAC to fire - each writing into its own module while an architect holds the whole.
Iterate with the next sentence
“Add a storey.” “Enlarge the south-facing windows.” The AI updates the model, versions sit side by side - and a built-in prompt advisor helps you write a better brief.
An editor like professional CAD
A ribbon, families with custom solids, DWG and PDF underlays, details, keynotes and sun studies. 78% of the features of established, expensive BIM software - in the browser, nothing to install.
Classical and modern architecture
Cornices, pilasters and balustrades as well as organic forms, cantilevers, curtain walls and timber cladding - from the palette or with a single sentence.
IFC import and round-trip
Open your own project from Autodesk or Civil 3D - IFC2X3 to IFC4X3. Every entity has a declared fate, and the model survives export and re-import without loss.
Data standard and classification
Typed IFC properties, IDS validation, the vocabulary of the Czech data standard (ČAS) and CCI classification right in the model.
Drawings, PDF and DWG
Plans, sections and the “Drawings for discussion” set generated from the model, with dimensions, annotations and hidden lines - not design documentation for a building permit. Export to PDF, DWG and DXF.
Construction scheduling (4D)
Activities bound to model elements, dependencies, critical path, calendars, resources and baselines. A Gantt inside the editor and a two-way MS Project exchange.
Quantity take-off and cost estimate
Volumes, areas and counts measured from the geometry, company price lists and AI pricing with an audit trail. Live recalculation as you edit, export to XLSX and CSV.
