Prefab Home 3D Configurator for Manufacturers in Spain
By Facundo Campo, 3D quoting tool developer
In short: A 3D configurator lets a Spanish manufacturer of precast concrete or modular homes have buyers design their home room by room, see it in 3D with their finishes and share it, while the quote comes from the manufacturer's own rules and prices.
A prefab home 3D configurator is a web app where the buyer designs their home —rooms, layout, roof, facade, finishes—, sees it in 3D while choosing and asks for a quote with the house already defined. For a manufacturer of precast concrete or modular homes in Spain, it answers the question every buyer has before signing: "how will my house look?", not "how did the show home turn out?"
What a home manufacturer sells in Spain
Spain's factory-built housing market has two big families, and each sells differently:
- Precast concrete prefab homes (casas prefabricadas de hormigón), with panels or modules made in a plant and assembled on the plot. Buyers value solidity and the feel of a "real house," and they ask a lot about the facade and the roof.
- Modular homes (casas modulares industrializadas), with steel or timber structures, delivered as modules and put together on site. Buyers value build time, efficiency and the option to expand later.
Either way, the manufacturer works from a catalog of models —single-story, two-story, with a porch, with a garage— and then adapts each one: an extra bedroom, the kitchen open to the living room, the porch on the other side, an upper floor. Those changes are what go through the architect or the engineering office for every inquiry today, and they eat the most time before you even know whether the customer will buy.
The buyer wants to see the house on their plot
The typical buyer has a plot (parcela) in a development outside Madrid, a village in Castile, the Málaga coast or inland Catalonia, and wants to picture the house there. They look at the catalog and photos of finished homes, but none of them is theirs.
The site's prefab home configurator shows how the first part can work: the house sits on a lot with a sidewalk and street, and the buyer sees it from outside and inside. Placing it on the customer's actual plot, with its dimensions, orientation and boundaries, isn't in the public configurator; it can be developed if your sales process needs it. What's there today:
- Floor plan editor: drag rooms, make them bigger or smaller, add bedrooms or bathrooms, edit doors, windows and the entrance, move furniture, undo and redo, see dimensions.
- Upper floor with stairs, choosing which way they go up.
- Flat, single-slope or gable roof.
- Facade: plaster with an accent color, brick, stone or wood cladding.
- Interior: ceramic tile, porcelain or wood flooring; real kitchen, bathroom, laundry and closet furniture; lighting.
- Exterior: porch, pool and a plot fence (wall, wire mesh or railings).
- Walk through the house at eye level, see it at night, and share a link with the exact configuration.
An example: a family near Valencia and a single-story home
A family with a plot near Valencia is looking at the three-bedroom single-story model. They want a bigger living room, an open kitchen, a porch facing the garden and a small pool.
Without a configurator, they email a question, the rep passes it to engineering, engineering edits the plan, and the quote arrives days later. If the family changes their mind, it goes around again. With a 3D configurator, the family enlarges the living room in the floor plan editor, opens up the kitchen, adds the porch, picks wood flooring and a white facade with stone, and shares the link with the parents helping pay for it. When they request a quote, the manufacturer gets the house fully defined and the rep quotes from there. If a combination isn't possible with your system —an opening a panel can't take, an upper floor on a module that can't carry it— the configurator's rules don't allow it.
I wrote about how the sale changes when buyers design room by room in prefab home 3D quoting tool, and how to use the editor is in floor plan editor for prefab homes.
Concrete or modular: the rules are the manufacturer's
Every building system has its limits. With concrete, panels have manufacturing sizes and window openings go where the panel allows. With modular, a module has a maximum transport width and rooms are split across modules. A generic configurator knows none of that; a custom one does, because the engine generates the house from rules your engineering team sets. I explain it in turning the owner's know-how into rules.
Permits and whatever each town council requires stay outside the configurator: that's for the project architect, and it's worth checking with a local professional.
What the manufacturer gains
- Inquiries with the house defined, instead of "how much is the Mediterranean model?"
- Less engineering work during the sales stage, because variations come from rules, not new drawings.
- Quotes in euros generated from the configuration, with a price table the manufacturer manages.
- Production that gets what was sold, without reinterpreting emails. See from quote to production.
Working with a developer in Argentina
I'm Facundo Campo, a software developer based in Quilmes, Buenos Aires, Argentina, and I focus on 3D quoting tools and configurators for manufacturers. I work remotely in Spanish and English; with Spain, my morning lines up with your afternoon. We start with a video call; you send me your catalog of models, plans, photos of finished homes and sample quotes, and I send you links to try each step in the browser.
If you build precast concrete or modular homes in Spain, message me on WhatsApp at +54 9 11 6193-3176 or email facundocampo100@gmail.com. I answer in English and Spanish. Or see how custom 3D quoting software works.
Frequently asked questions
Can the customer see the house on their own plot?
In the public configurator the house sits on a suburban lot with a sidewalk and street. Placing it on the customer's real plot, with its dimensions and orientation, can be developed as a custom feature; it isn't running in the public configurator today.
Can I load my catalog models?
Yes. Your models are loaded as starting points, and buyers modify them within the rules of your building system, whether concrete or modular.
Does the configurator have augmented reality?
No. Estructuras 3D configurators run in the browser on a computer, phone or tablet, without augmented reality.
Does it show the price to the buyer?
The public configurators don't show prices. In a custom build you can show a reference price in euros or keep it for the sales rep only, whichever you prefer.
