Concept Development

Our process transforms bold concepts into timeless designs that enhance spaces and lives.

We fuse creativity with precision across two dynamic phases:

Concept Development powers Phase 1: Sketch Design & Phase 2: Preliminary Design.

Engineering

At Tjep, engineering brings visionary designs to life.

We fuse cutting-edge computational tools with sustainable precision and innovative production techniques. Our meticulous approach guarantees every project is structurally robust, budget-conscious, and ready to shine.

Engineering powers Phase 3: Design Finalization.

Realization

Our realization phase delivers expert production guidance.

We steer fabrication with precision, aligning innovative designs to sustainable practices and tight timelines. As your turnkey solution, we transform concepts into complete, ready-to-install creations—delivering high-impact results from vision to execution.

Realization powers Phase 4: Production, Installation & Evaluation.

Project Management

Solid project management ensures seamless execution.

We guide every design decision from vision to reality with precision and efficiency. Our dedicated approach aligns innovation, sustainability, and client goals to deliver impactful, high-quality results—while maintaining firm budget control.

Project Management powers every phase: Inception through Realization and Evaluation.

Identity Design

Identity Design shapes distinctive brands that inspire.

Our core competence is 3D design, but we love weaving in 2D design as an integral part of any 3D project. This can include naming and full brand identity creation.

Identity Design powers all phases of the project when applicable.

Keynote Speaker

Keynote Speaker Frank Tjepkema captivates with visionary keynotes on design's evolution.

From the satirical Bling Bling—layering global logos into a consumer culture critique—to its evolution into Logos, a dynamic digital artwork animating 160 deconstructing brand icons in the metaverse, his work pushes boundaries. His innovative Oogst research, timeless Bronze Age Collection, and bold public space projects like the reimagined Paleis Het Loo entrance gate ignite inspiration.
