Discover the timeless craft of Japanese joinery through hand sketches, detailed analysis, and 3D models designed for architects, designers, and furniture makers who want to understand, study, and apply these beautiful principles in their own work.

Japanese joinery is more than technique — it’s a philosophy of design, balance, and precision. Whether you’re an architect, designer, or craftsperson, understanding these joints unlocks new ways of thinking about proportion, material honesty, and structural beauty.

But most resources are either overly technical or too abstract.
This guide bridges both worlds — a visual and practical study that combines hand sketches, 3D renders, and downloadable models.

What’s inside Interlocking Elements?

Hand-Sketch Studies of 30 Japanese Joints

Each joint is broken down with hand-drawn sketches and visual mind maps, making complex joinery instantly clear and easy to understand.

3D Rendered Diagrams

Each joint is professionally modeled and rendered, giving you clean, accurate visuals that reveal exactly how the elements interlock.

Downloadable 3D Models

Take the study further with ready-to-use 3D models. Perfect for architects, designers, and makers who want to build, adapt, or experiment digitally.

  • We begin with an in-depth look at the new Midjourney interface, moving away from Discord. Explore key features like the Retexture Tool, Image Editor, Remix Tools, and Personalization options.

  • Master the art of crafting precise prompts to generate high-quality interior design concepts. Learn how to structure prompts for better control over style, materials, lighting, and composition. Explore advanced techniques like weighted keywords, negative prompts, and style modifiers to fine-tune your results.

  • In Chapter Three, we get straight into Moodboard Prompts—learning how to generate high-quality material concepts, explore unique combinations, and create visually compelling moodboards in seconds.

  • In Chapter Four, we dive deeper into materials and textures, using Midjourney as a research tool—exploring wood, stone, metal, and fabrics like never before. Experiment with textures, finishes, and combinations, refining your understanding of materiality through AI-driven exploration.

  • In Chapter Five, we use Midjourney as a tool to analyze color in interior design—breaking down palettes, contrasts, and harmonies directly from AI-generated images. By studying how Midjourney interprets color relationships, we refine our understanding of balance, mood, and cohesion, helping us make more informed design choices.

  • In Chapter Six, we transform our AI-generated moodboards into interior views, creating concept images that align with our material and color choices.

  • In Chapter Seven, we use Midjourney to explore abstract details—zooming in, reinterpreting textures, and generating rapid iterations to uncover unexpected design possibilities. This process helps refine ideas, experiment with composition, and bring new depth to our concepts.

  • In the Bonus Chapter, we use Midjourney to generate unique furniture concepts, exploring form, materiality, and detailing. From sketch ideas to refined iterations, we rapidly visualize and experiment with new designs.
