3D illustration of a sketch: A Danish client's hand-drawn plan turned into an apartment building

Do you have a plan quickly sketched on paper, but need representative drawings and a 3D view suitable for sale? That's exactly what we do at Ruut24 every day - we create a 3D illustration from a sketch , which helps turn an idea into a clear and sellable solution.
Below is an example from Denmark, where an existing building was re-planned into three apartments and the whole story moved from paper to a photorealistic 3D image.
Customer story from Denmark: from paper plan to apartment building
The Danish client had:
hand-drawn floor plan;
simple facade sketch;
photos of the existing house.
The goal was simple, but demanding: to show officials, investors, and future tenants what the building would look like after the renovation .
Our work is complete:
accurate floor plans based on the sketch;
exterior views (facades) with dimensions;
A photorealistic 3D illustration of the sketch , showing the new volume, materials, and surroundings.
Result: the client received a consistent and professional set of images to use in both project coordination and sales work – and was very satisfied with the work.
Step-by-step journey: sketch → CAD → 3D illustration
1. Hand-drawn sketch or photo
You can start with very simple materials:
sketch taken with a phone;
old paper drawing;
or a diagram quickly drawn on paper.
It is important that the basic dimensions are at least approximately known – we will specify the rest. This way, the initial sketch becomes the basis from which a 3D illustration of the sketch will later be created.
2. Digitization and floor plans
Next, we digitize the sketch:
we transfer rooms, walls, windows and doors to the CAD program;
we add dimensions and room names;
We design the plan in a consistent, easy-to-read style.
The result is a correct floor plan that is suitable for both official documentation and sales plans.
3. Facades and exterior views
To understand the volume and appearance of the building, we also create exterior views :
we draw facades based on photographs and sketches;
we place windows, doors and awnings in the right places;
We take into account the roof shape and other details.
Facades are necessary for both the construction project and the subsequent 3D model.
4. Photorealistic 3D illustration from a sketch
Once the plans and facades are in place, we move on to the 3D stage:
we model the existing building and the planned extension;
we add materials (facade plaster, wood, roof, window frames);
we create realistic light, shadows and the surrounding environment;
we place the building in the same view from which the client sent the photos.
This is where the final 3D illustration of the sketch is created – an image that looks like a finished photograph of the house of the future.
Why order a 3D illustration from a sketch?
Clear visuals for all decision-makers
It is easy for officials to understand exactly what is being planned.
Investors can assess the potential of the project.
Prospective tenants or buyers can see what their new home or office will be like.
Fast and cost-effective solution
You don't need an expensive and detailed project package. A sketch or paper drawing is enough, based on which we will create:
floor plans,
facades,
and, if desired, also a sketch of the entire 3D illustration .
This is often faster and more affordable than commissioning a completely new project and is particularly suitable for buildings where the basic framework already exists.
Suitable for both sales and design
The finished materials are useful for:
in real estate advertisements and sales presentations;
in communication with investors and banks;
when applying for a building permit (with the necessary plans).
Ruut24: we digitize plans and create 3D visualizations around the world
Ruut24 works completely digitally – our services can be used from any country in the world. We have created floor plans and 3D illustrations from sketches for clients in Denmark, Norway, Sweden, Finland, Germany, the USA and of course Estonia.
Our main services:
digitizing hand sketches, photos and PDF drawings;
floor plans for real estate sales and projects;
facades, sections and other technical drawings;
photorealistic 3D visualizations from single-family homes to smaller apartment buildings.
If you need to simply and clearly show what your building will look like, a 3D illustration from a sketch is one of the fastest ways to get there.
How to start?
Take a picture of a sketch or drawing with your phone or scan a paper plan.
Send the files by e-mail to info@ruut24.com .
Add a short description:
do you only need floor plans;
floor plans and facades;
or a full solution, where the end result is a photorealistic 3D illustration of the sketch .
We usually respond within 1 business day with a specific quote and deadline.
Summary
The Danish client's project shows how much can be done with a simple sketch on paper. For us, this is just a starting point - we then create accurate floor plans, facades and photorealistic 3D illustrations from the sketch , which will help you present and sell your idea with confidence.
