3D Model Gallery & Roof Structure | Single-Family Home in Meggen, LU

Initial Situation
An existing single-family home with an appearance that seems conventional at first glance—but with an interior layout that’s quite something: an open gallery level above the main living area, a freestanding fireplace serving as a space-defining element, a single-flight spiral staircase spanning multiple levels, and a roof structure featuring offset ridges, dormers, and cantilevered wooden purlins.

The client needed a reliable as-built documentation—as the foundation for upcoming renovation planning.

Services Provided by VDE
VDE fully surveyed the building using terrestrial 3D laser scanning. From the point cloud, a structured BIM model was created featuring:

• Architecture, including all variations in room heights and the gallery level
• Roof structure with dormers, staggered ridges, and timber construction
• Interior elements (fireplace, staircase, railings)

Result
The as-built model provided the planning team with a precise, three-dimensional foundation—no interpretations, no measurement gaps. In particular, the spatial interplay between the gallery, staircase, and roof geometry would have been only partially captured using conventional manual measurement methods.
