Walk the space before it exists.

Prewalk is a video channel about how buildings feel, how they are made, and the tools that let us test them first: BIM, virtual reality and new building technology.

Four things we keep coming back to

Every video starts from a real architectural idea and explains it in plain language, with images you can follow even if you have never opened a CAD program.

How space feels

Why some rooms feel bigger, calmer or heavier than they are. Light, proportion, ceiling height and the tricks designers use.

Spatial perception

How buildings are made

New materials and construction methods, from steel warehouse sheds to residential towers, seen from inside real projects.

Building technology

Tools that let us test first

BIM, real-time rendering and VR headsets: walking through a design at full scale before a single wall is built.

BIM and VR

Buildings that look after themselves

Sensors, maintenance and smart buildings that notice their own problems before the people inside do.

Smart buildings

Start with the first episode

Why do some spaces feel bigger than they are?

A short look at how proportion, light and sightlines change the size a room seems to be, and how architects use that on purpose.

Let's work together

Prewalk also takes on project work: letting clients walk through a building before it is built, and helping brands in architecture and construction reach the channel's audience.

VR walkthroughs
Your design as a tour you can walk through on a Meta Quest headset or in a web browser, for client meetings, approvals and sales.
BIM modeling
Revit models built from your drawings, ready for coordination, quantities and visualization.
Renders and animations
Still images and walkthrough videos made with Enscape, Twinmotion or Lumion.
Sponsorships and collaborations
Video partnerships for software, materials and building-technology companies.

Pricing and common questions

How pricing works

Every project is different, so there is no fixed price list. The quote and timeline depend on:

Size and number of spaces to model and finish
What you already have: a Revit model, CAD drawings or only sketches
Level of detail in materials, furniture and landscape
Delivery format: headset app, web tour, video or images
Your deadline

Send your drawings through the form and you will get a quote and timeline for your project, free and with no commitment.

Questions

What files do I need to send?

A Revit, SketchUp, Rhino or ArchiCAD model is ideal. CAD drawings or PDF plans and sections also work; the model is then built from them.

Do my clients need a VR headset?

No. The web tour opens on a phone or laptop. A headset makes it more immersive, and the tour can also be delivered as a standalone app for Meta Quest that runs without a computer.

Can I review the work before it is final?

Yes. You see a draft before final delivery, so changes can be made while they are still easy.

Do you work with clients in other countries?

Yes. Everything is done remotely: files, reviews and delivery all happen online.

Made by a working architect

Prewalk is run by Soheil Vahedi, an architect who works on BIM for large residential towers and has designed industrial projects such as warehouse sheds, loading docks, pumping stations and electrical substations.

The channel grew out of building VR walkthroughs for real projects and wanting to explain, simply, why spaces work the way they do. Over time Prewalk will also share tools and software made for architects.
