Popular questions
Couldn't find the parts you need to create your figurine
Most parts are already in our builder. But if you can't create yourself with the available parts, we can produce a part specially for you or change its color.
Just write to us in any messenger.

Calculate the cost of your set
Pick a size and the options — we'll show an approximate total. The final price is fixed once we've seen your idea.
1Set size
Most ideas land between 300 and 1000 parts — almost every order falls into this range.

Get an exact quote
The price is per set. This estimate is preliminary and is not a binding offer. If you need several identical sets we'll quote them separately — it works out cheaper.
We budget the design with headroom
How complex a scene really is only becomes clear during the work: sometimes the designer goes beyond the planned range. That's why the calculator already assumes the upper limit — so the price doesn't grow mid-project.
Design — paid upfront
The design stage is paid upfront: it is separate work by the designer that starts before any parts are bought. It isn't an extra charge — it's part of the total.
Parts — at the maximum price
Until there's a final parts list we price them at the highest possible rate. In practice some parts turn out cheaper — and the final total is almost always lower than shown here.
Price list
Prices by set size
If you'd rather not do the maths — the same numbers in a table.
| Set size | Parts | Price from | Design deposit | Custom box optional | Printed instructions optional |
|---|
The last two columns are optional. The "from" price already includes standard packaging and digital step-by-step instructions — that's everything you need to build the set. A custom box and a printed booklet are only needed if the set is going out as a gift.
All prices are per set. If you need several identical sets we quote them individually: the design, the box and the instruction layout are paid once for the whole run, so every additional set comes out noticeably cheaper.
Prices are approximate: we budget the design at the top of its range and the parts at the maximum price. The final amount is fixed once we've seen your idea and is usually lower than shown here.
How it works
From an idea to a real building set
You can come with a photo, a description or an AI visual. We'll check what can realistically be built, design the set in dedicated software, source the parts and prepare it as a proper gift.
-
You send us the idea
A photo, a description, a sketch or an AI-generated visual. It can be a house, a room, a piece of decor, a miniature scene or any place that matters to you.
-
We discuss how to build it
We look at your idea and explain what can realistically be built from bricks: which elements can be reproduced exactly and which are better adapted.
An AI visual is a reference. The real resemblance depends on the parts, the scale and the budget.
-
We agree on the format and budget
Together we settle the size of the set, the number of parts, how complex the scene is and the format: a standard set, a gift box or custom packaging.
-
We design the set
A specialist builds your idea in professional software: refining the shape, the details, the colours, the stability of the build and the future instructions.
This is a separate stage handled by a designer who specialises in custom sets.
-
We source the parts
Once approved, we draw up the parts list, pick the right colours and order everything your set needs.
Some parts may be sourced individually for your project.
-
We pack and ship
We prepare the set, the instructions and the packaging. If you chose a gift box, we design it around your idea. You get a finished, one-of-a-kind set.
What's included
Tap an item to see the details. Everything is included — no hidden extras.
-
Idea review
We look at your photo, sketch or description and explain what can realistically be built from bricks. We agree on the key elements and the level of likeness.
-
Adapting to real parts
We translate your idea into the language of bricks: choosing shapes, colours and parts that can actually be built, without losing the character of the idea.
-
Digital set design
The designer builds the model in dedicated software: refining the shape, the details, the colours and the stability of the build.
-
Building instructions
We prepare step-by-step instructions so the set can be built without anyone's help — just like factory sets.
-
Packaging
We pack the set with all its parts and the instructions. On request — in a custom gift box.
Your project in the hands of a true professional
Your order will be handled by Anton — an experienced builder enthusiast and creator of unique custom sets.
Frequently asked
How does payment work?
The first look at your idea and a rough estimate are free. If the format and the approximate budget work for you, the next stage is the paid design project. Once the design is approved we calculate the final price and start production after a deposit.
Can you add minifigures of people or pets?
Yes. You can add minifigures of people, pets or the key characters of the scene. We adapt how they look to the style of the set and the parts available.
Will the set look exactly like the AI image?
An AI image is a reference, not the final design. We keep the main idea, the composition, the colours and the recognisable details, but we adapt them to real parts, scale and what is technically possible to build.
Can I order without an AI mock-up?
Yes. Just send a photo, a description, a sketch or an example of what you want. An AI visual only exists to show your idea faster.
Why can't you give an exact price right away?
Because every set is made individually. The price depends on the number of parts, the complexity of the shape, the size of the set, the colours, the minifigures, the instructions and the type of packaging. First we assess the idea and give a rough budget, and after the design — the final price.
What's included in the price of a set?
The price can include reviewing the idea, adapting it to real parts, the digital design of the set, sourcing the parts, building instructions, packaging and, if needed, a custom box.
Will there be building instructions?
Yes, we can prepare building instructions for a custom set. How detailed they are depends on the size of the set and the number of parts.
Can you make a gift box?
Yes. We can prepare standard packaging or a custom box or sleeve designed around your idea. Custom packaging is quoted separately.
Can you build any idea?
We try to keep your idea as close as possible, but some shapes, very small details or complex organic forms may need simplifying. At the first stage we tell you honestly what can be built and what is better simplified.
