ISB® Building System

How It Works

From building system to completed structure.

ISB® connects architecture, engineering, system planning, production and construction within one coordinated project route — turning a building concept into a buildable structural system and, ultimately, a completed building.

From System to Building
Designed as a System

The system begins before construction starts.

ISB® planning starts with the building itself. Architecture, structural requirements and system geometry are coordinated before elements reach the construction site.

01

Architecture

Site, programme, spatial organisation, openings and architectural expression define the building that must be realised.

02

Engineering

Structural requirements, loads, geometry and project conditions are translated into an engineered building concept.

03

ISB® System Planning

Wall and floor elements, reinforcement and connections are coordinated around the architecture and structural design.

INPUT Site + Brief + Architecture
COORDINATION Engineering + System Planning
OUTPUT Buildable Structural System
From Design to Elements

Project planning becomes physical components.

Once architecture and engineering are coordinated, the structural concept is translated into wall and floor elements that follow the geometry and requirements of the building.

Wall Elements

Wall elements are arranged according to the building geometry, openings, structural requirements and connection strategy developed during system planning.

Floor Elements

Floor elements extend the coordinated structural system horizontally and are planned together with wall positions, reinforcement and wall-to-floor interfaces.

Assembly Logic

The structure develops from connection to connection.

Construction follows the system logic established during planning. Base conditions, wall junctions and floor interfaces connect individual components into one coordinated structural route.

Start at the Base

The structural wall system begins at the foundation interface, coordinated with the floor construction and surrounding envelope.

Connect the Walls

Corners and intersections establish continuity between wall directions and coordinate the structural layout of the building.

Add the Floor System

Horizontal floor elements connect with the vertical wall system through coordinated reinforcement and connection detailing.

One Coordinated Workflow

The building process stays connected.

ISB® is designed as a project route rather than an isolated material supply. Information moves from design through engineering and element planning into production preparation and construction.

01

Design

Architecture establishes the form, spaces and project requirements.

02

Engineering

Structural requirements and project conditions are defined.

03

System Planning

Wall, floor, reinforcement and connection logic are coordinated.

04

Production

System planning is translated into the information required for elements.

05

Assembly

Elements and connections form the planned structural system on site.

06

Building

The structural system becomes part of the complete finished building.

The Principle

One project route. Multiple professional disciplines.

Architects, engineers, system planners, production and construction teams remain separate professional roles — but the project information connecting them can follow one coordinated building route.
