How house manufacturers and architects use AR to sell homes before they're built

When we started Overly, house building wasn’t the first industry I had in mind for AR. Today I think it’s one of the best fits. Prefab and modular builders, tiny house and sauna house makers, A-frame specialists and architecture studios are very different businesses, but they share one problem. Their clients love the idea of a new home, but they hesitate when it comes to deciding, because a floor plan and three renders are not enough to imagine living in it.

In this blog, I share where augmented reality actually helps the sales process, how manufacturers and architects use it, and, honestly, what it can’t do.

Why homes are so hard to sell from a catalog

A house is one of the biggest purchases people ever make, and with prefab and modular homes, they often have to decide without ever standing inside the model they’re buying. The show home is in another country, the trade fair stand fits one unit at best, and the website shows the same renders as every competitor.

So the client starts asking questions. Will it fit on our plot? How big is it really next to our old house? Where will the terrace face? What do you see from the kitchen? Every one of these questions means another email, another call or another trip to a show home. For the manufacturer, that’s a longer sales cycle. For the client, it’s uncertainty, and uncertain clients don’t sign.

Architects know the same problem from a different side. Clients nod at drawings and then get surprised on site. Planning boards and neighbours have to imagine a building from elevations. Every misunderstanding costs time, and sometimes the project.

What augmented reality changes

With AR, the house stops being a picture and becomes an object the client can walk around. Using just a phone or a tablet, there’s no app to download: the client scans a QR code or opens a link, and the 3D model appears in the room or outside.

In practice, we see it used in two ways:

• On a table, like a dollhouse. A 1:10 model on the kitchen table, the office desk or the fair stand. People walk around it, look at it from every side and scale it up or down with their fingers. If you prepare a version without the roof, they can look straight into the layout.
• At full size, on the plot. The same model at its real size, placed on the ground where the house will stand. This is where the questions about fit, proportions and orientation get answered in seconds.

The phone does the tracking itself (ARKit on iPhone, ARCore on Android), so it works on most phones people already have. It also works for every type of home: modular and prefab houses, tiny homes and container houses, sauna houses, A-frames, houses on wheels and other portable living spaces.

Where manufacturers and architects use it

Here are the places where AR makes the biggest difference:

1. Product pages on your website. Every house model gets a “View in your space” button next to the photos. Visitors who use it are the ones seriously considering that house.
2. Printed catalogs and brochures. A QR code next to each model turns a paper catalog into a 3D showroom.
3. Trade fairs. Your whole range fits on one table, at a scale that works on any stand.
4. Sales meetings and plot visits. The client and the salesperson stand on the plot together and place the house where it will be built.
5. Architects’ presentations and public consultations. Clients, planning boards and neighbours see the building in its real surroundings.

Two projects from the real world

Public dialogue in urban development

In collaboration with a national government body, AR was used to let citizens preview a proposed public building in real space. Through their smartphones, they could walk around a future cultural centre, leave comments and take part in the design feedback loop. In UNESCO zones, AR can even replace 1:1 physical mockups, saving materials and space while giving far more visual clarity. And it opens public participation to more people than the ones who come to committee rooms. Project author Māris Putns from Studio Perspective.

How it works with prefab houses, shot in the field

This short video shows how it works in real time on prefab houses, filmed outdoors on site. You can see how quickly both the builder and the client get the full picture.

See it in action

Try it yourself. Open these demos on your phone, or scan them from your screen.

Place the house on any surface, walk around it and scale it up. The model is static, but it gives real scale and real context.

What you need to get started, and what to expect

The good news: most manufacturers and architects already have what’s needed. If your houses are designed in SketchUp, Revit, ArchiCAD or a similar tool, the 3D model already exists. It just has to be prepared for mobile, because a model built for construction drawings is far too heavy for a phone. We simplify the geometry and textures so the model loads quickly and still looks right.

To set expectations straight, a few honest limits:

• The models are static. Doors don’t open and you can’t switch materials or colours inside the AR view. If you need variants, we prepare them as separate models.
• Full size works best outdoors on open, fairly flat ground in daylight. In a small garden or a dark room, the tabletop scale is the better choice.
• A show home and a site visit still matter. AR makes sure that when the client comes to one, they already know which house they want.

There’s also one benefit people rarely expect: every scan is counted. You see which house models people actually open in AR and how long they look at them. That tells you more about real interest than page views do.

How we can help

For manufacturers and architects, we usually take care of the whole thing as one project: we prepare your 3D models for mobile, create the AR links and QR codes for your website, catalogs and fair stand, and set up the scan statistics. You don’t need anyone technical on your side. Send us one of your house models and we’ll show you how it looks in AR before you decide anything.
