DIGITAL VS PHYSICAL?
Most products are digital-only. They include templates and instructions you can download and assemble yourself—nothing physical will be shipped. Each one comes with everything you need to get started at home, whether you’re cutting by hand or using a machine.
If you prefer ready-made pieces, I also offer a small selection of pre-cut paper models and greeting cards. You can view them by clicking the button below.

What's included in your download
- Printable PDF templates for manual cutting
- DXF / SVG vector files for cutting machines (Cricut, Silhouette, etc.)
- Step-by-step assembly instructions in PDF format
You’ll only need a few basic tools—printer, knife, ruler—and some time to build. It’s a simple and satisfying way to explore form through paper.
Get Started
ARCHETYPES
This series began during lockdown, when I no longer had access to my studio to create the concrete sculptures that usually form the core of my artistic practice. It started as a personal challenge: could I translate my work into a completely different material, using techniques that were its opposite?
I decided to add another constraint using just a single sheet of standard paper, with no glue—following the principles of Japanese Kirigami. Unlike the better-known Origami, Kirigami allows cuts as well as folds. What began as a creative challenge quickly turned into a passion, then an obsession. What you see here is part of that exploratory journey.
ASSEMBLAGES
The models in this series are more intricate, reflecting the architectural language of my concrete work.
They’re designed as standalone sculptures—something you can keep, display, and interact with over time. Some include modular components, giving you the freedom to follow my original layout or experiment with your own combinations.
CUTOUT CARDS
These templates let you create original farewell cards from simple sheets of paper—easy to assemble, fun to put together, and designed to be shared.
Mix and Match
Each design includes a cover and a matching insert, but all elements within the same series are interchangeable. You can combine them freely to create different variations with just a few adjustments.
Combine Across Sets
You're also free to blend pieces from different sets. Some combinations will work better than others, but experimenting is part of the process.
Print, cut, and fold—by hand or with a cutting machine. No glue required. The result is a thoughtful card you can offer, frame, or keep.
HOUSES
This series takes a more direct cue from real buildings—specifically, houses. While the forms remain minimal, they echo one of architecture’s most fundamental themes: the idea of home. My architectural background is especially present here.
The Tiny Houses are a great entry point for beginners, while the Modern Houses offer a bit more complexity and a satisfying build experience.

No-BU-RU: Art, Design & Architecture
My name is David Umemoto. My journey into the arts began as an architecture intern during the early days of computer graphics.
During the pandemic, unable to access my art studio where I created my concrete sculptures, and confined at home, I sought a way to continue my creative work while involving my two young children. My work with paper began as a personal challenge: could I translate my sculpture and architectural work into a material as different as paper? Through this platform, I share pieces of that creative journey with you.

About Physical Products
If you’re looking for something ready-made, I also offer a series of finished paper objects you can gift, display, or keep.
These are hand-assembled pieces, made from cardstock in my Montreal studio and shipped directly to you.
Many of the designs are based on the same models found in the digital section—some are nearly identical—but here, the work already done for you.
