For designers
The next step – without hassle
We make designers’ everyday life easier by offering direct support and functional stair solutions. When design is done together and in time, the project progresses smoothly also on the construction site.

A staircase is part of the structure, not a separate product. The designer must choose a solution that works in the project’s use, environment, and life cycle. Over 50 years of experience shows in knowing how to guide in the right direction. We don’t push a model, but seek a solution that withstands scrutiny and implementation
Supporting the designer from the start
Our design service is not just a promise but a tool that makes the project functional from the start. Designers receive precise production drawing sets and 3D views often already at the quotation stage, which reduces interpretation and ensures that the solution fits into the structure without correction rounds.
LK Design System (LKDS) is a design tool that speeds up and clarifies stair design and dimensioning. With it, 3D models and changes can be made in minutes, not days
This is why designers can trust that the dimensioning is correct, the documentation is in order, and deliveries come on time. No guessing rounds, no unclear points, but solutions that also work on the construction site.

LKDS – digital machine shop
LK Porras Design System (LKDS) is our way to make stair design faster and more reliably feasible. It combines design, dimensioning, and production into the same whole, so that solutions don’t just stay on paper.
- Speed: images suitable for the construction site and designers included already at the quotation stage
- Reliability: dimensioning and structures are based on modular solutions
- Smoothness: the plan moves directly to production without unnecessary intermediaries
