RENDER13 – Interior design and 3D visualization studio
Design that tells your story. Solutions and visualizations that bring your story to life.
I help people create their dream space – whether it’s a warm, functional interior or an impressive, harmoniously designed exterior.
ABOUT ME
RENDER13 is run by me as the founder, and I collaborate with experts from various fields, from architects to contractors and furniture manufacturers.
Interior design has been a hobby for me for years, and through concrete experiences and projects it has grown into a professional profession, especially through 3D modeling and rendering.
Today, I combine technical knowledge and experience in space planning to help clients clearly see and understand their space – through interior design concepts and photorealistic 3D exterior visualizations. In addition, I connect them with proven contractors when necessary.
Through design, I create spaces that attract, relax and inspire – before they are decorated or built. This gives clients security, clarity and better control over the project, without unnecessary doubts or mistakes.
Also, the visualizations I create are of great use to investors and real estate agents (agencies) in encouraging the sale of undeveloped or undeveloped properties.
I try to provide something new, my own stamp, with every project, and in doing so, I give my best.

SERVICES
INTERIORS
Together we define the functional layout, style and atmosphere of the space. You can choose the service as a basic or extended project, depending on how much help you need in the implementation.
Basic project:
2D floor plan of the space with furniture layout
Photorealistic 3D visualizations
Extended project (all basic + additional as desired):
Custom furniture drawings + material suggestions
Catalog of standard furniture and lighting with discounts
- Lighting, socket, water and drain layout
- List of sanitary facilities + layout of coverings and decorations
- Budget for all interior design elements
At the end: You get a finished and clear PDF document, with a high-resolution visualization render, ready for use or sending to contractors.
EXTERIORS
Based on your documentation (conceptual, main, detailed design, floor plan, facades…), I create photorealistic visualizations of the object and its surroundings. If necessary, I add additional details – everything that the buyer, investor or you need to clearly see what is coming.
Which includes:
Exchange of ideas about the appearance of the object and its surroundings
Modeling and creation of visualization in several steps
Revisions and refinements based on your feedback
High-resolution renders (PNG) ready for presentation, sale or decision-making prodaju ili odluke
If the client sends photos of the location, I can integrate the object into the existing image — for an even more realistic impression.
ADDED INFORMATION
All projects are carried out exclusively online – via phone or video calls, messages (Messenger, Viber, WhatsApp) and e-mail – without going out into the field.
📩 The client submits documentation, photos and video materials by email.
In the same way, I send variants for revision through the stages of production, as well as finished conceptual solutions / interior design projects and final 3D visualizations.
