3D Visualisations for House Manufacturers Before the Prototype: What to Order and in What Order? Based on the Seven Models of Mök. majad
A house manufacturer should order 3D visualisations when sales have to start before the first house is finished — the website, the product catalogue and the exhibition stand cannot wait for the prototype. In that case the order matters: first the floor plan from the manufacturer, then the 3D model and its approval, and only after that a front view of every model, a 3D floor plan, an interior view and material options. This guide walks through the steps using a real example. Mok Houses OÜ (Mök. majad), an Estonian house manufacturer, started in autumn 2025 without a single finished house and ordered the visuals for seven house models between January and May 2026. At the time of writing, its website carries more than 40 images made by us.
When should a house manufacturer order 3D visualisations before the prototype?
When the buyer has to decide on the basis of an image. A manufacturer who builds to order cannot wait until the first house is finished and a photographer arrives — the website has to be live before that. Mök. majad’s initial brief was simple: a product catalogue that looked polished, attractive and realistic rather than cheap. Sketches and diagrams do not give the same spatial impression. The buyer wants to see what the house looks like as designed, how the rooms are laid out and what the interior is like.
Two situations where it is better to wait: when the floor plan is still being developed (every change on the plan is a change in the model and new images) and when a single house is being sold that can soon be photographed. For a product range with several models, each needing images of the same quality, visualisation is a practical way to get a consistent catalogue before production. We wrote earlier about how visuals support modular house sales using the example of Timbeco.
What does the manufacturer send?
A floor plan — even a hand-drawn sketch — showing dimensions, wall thicknesses, window and door positions, and furniture. In addition, the heights that a plan does not show: building height, ceiling height, roof build-up thickness. And the materials: facade cladding (Corten steel and timber cladding in the case of Mök. majad), interior lining, flooring. For Mök. majad the floor plans came from the manufacturer’s designer. The architectural design is the manufacturer’s; we created the 3D models and visualisations based on it.
One boundary is worth knowing in advance: 3D visualisation does not replace design work, and we do not design. If the plans are still at the idea stage, they need to be turned into dimensioned drawings before the model — how a sketch becomes a set of drawings for planning or building approval and when you need a designer is covered in our guide to building permit drawings.
Step 1: the 3D model and its approval before any images
The first thing we send the manufacturer is not a finished image but a set of working views of the model: a cut-away top view and an exterior view straight from the model, without lighting or materials. The manufacturer reviews them as they would technical drawings: does the sauna bench have two tiers? Is the door glazed? Is the cabinet in the entrance area the right height? On the first Mök. majad model, the sauna bench and the glazed door were confirmed using the model’s working views and resolved straight away. The lower cabinet with a TV, however, only came up when the finished images were being reviewed — and that meant redoing three images. That is exactly why it pays to go through the model’s working views properly rather than wait for the finished picture.
The model also raises questions that the floor plan does not answer: is the window height 2100 mm or 2400 mm, is the ceiling height 2500 mm or 2800 mm, is there a post in the middle of the large window. These are decided by the manufacturer, not the visualiser — but they should be decided before the images, because a change at the model stage is usually easier than after the final views are done. On the second Mök. majad model, both the window and the ceiling height were agreed from the model’s working views, before a single final image was made.
Step 2: one front view of every model
The backbone of the catalogue is one front exterior view of each model, taken from the same angle. The Mök. majad team decided this themselves: one image per model, all straight from the front, on a white background, with the plan underneath. This lets the buyer compare models and lets the web designer place the images in a consistent grid. In a product range it makes sense to standardise the views that every model has — the front view and the 3D floor plan — and to keep evening forest views and interior details for highlighting individual models and for social media. Views with forest and sky can be beautiful, but in a catalogue they can distract from side-by-side comparison of the models.
Step 3: the 3D floor plan
The front view sells the feeling, the 3D floor plan sells the space. A model seen from above shows the buyer the room layout, whether the furniture fits and where the windows are positioned — things that may be less immediately clear to a non-technical buyer from a conventional black-and-white floor plan. From the same model we can also produce a 3D floor plan for the product page without a new model.
With Mök. majad the 3D floor plans did what they often do: once the rooms could be seen in three dimensions for the first time, this prompted changes to the plans — including the position of the WC and swapping the basin and toilet so that the toilet was not directly visible from the doorway. The manufacturer had the designer update the drawings. That is the second value of the 3D floor plan: seeing the spatial layout in 3D brings questions and change requests to light before production, not afterwards.
Step 4: the interior view
For the interior view, a 3D model is a necessary part of our workflow. With Mök. majad we first tried a faster route — images without a 3D model, based on an existing image and the floor plan. The exterior looked good, but the windows were not the right widths and the furniture layout did not match the plan. A buyer who compares the image with the plan notices that. So a proper 3D model was made of every house, and the interior view was rendered from the same model with the furniture layout set by the manufacturer.
Step 5: material options
Once the model is approved, producing options from the same model is usually a smaller job than creating a new model. The Mök. majad sauna house was shown in three cladding variants from the same model: black, dark grey and brown timber cladding — the same house, the same angle, the same terrace. In total we produced 32 cladding views for the manufacturer’s models, and the buyer can pick a tone on the product page without anyone having to build anything. The same logic applies to colours, roofing and window frames: in our workflow, the variant is created in the model rather than edited onto the finished image.
How many images per model are needed?
For Mök. majad, three: one front view, one 3D floor plan and one interior view. That is how the manufacturer put it — more images would make the choice confusing for the buyer. It is one manufacturer’s choice, not a general rule, but a good starting point: three views cover the exterior, the layout and the feel of the interior. If the images are going on Instagram, ask for a 4:5 or 1:1 format straight away — the landscape image from the website may need cropping there.
The example of the seven Mök. majad models
Mok Houses OÜ is an Estonian house manufacturer founded in September 2025: sauna houses, holiday houses and family houses. We made the 3D models and visuals for seven models from its floor plans between January and May 2026. There are ten product pages (some models have S and M versions), and all the product images on those pages are rendered from the 3D models.
Frequently asked questions
Does the floor plan have to come from a designer? Not for the visuals — a dimensioned sketch showing walls, windows, doors and furniture, together with the heights, is a sufficient starting point. The building design itself is a separate job done by a designer; we do not design.
What happens if the plan changes later? The change is made in the model and the affected views are re-rendered. That is why the model is approved before the images — a change at the model stage is usually easier than after the final views are done.
Can more images be added later? Yes. A new view, a new cladding variant or an Instagram format is produced from the same model without starting from scratch.
Send the floor plan — get a quote and a deadline
Before sending an enquiry, put together:
the floor plan — PDF, DWG or a dimensioned sketch;
the heights — building height, ceiling height, roof build-up thickness;
the materials — facade cladding, interior lining, flooring;
the number of models and the views you want (front view, 3D floor plan, interior view, options).
If some of this is still being decided, we start from the floor plan and settle the rest on the model. Send the files to info@ruut24.com — we review them and send a free quote with a deadline.
