CTHB Law Office Interior, Istanbul by Salon Architects

  • Comment

Lighting fixtures align with the tectonic of the design language in Salon Architects’ CTHB Law Office interior, writes Alper Derinbogaz

The architect’s view

This is a refurbished space in an office building, structured within a repetitive standard construction grid. The interior challenges this rigid grid to create tension between the rectilinear and non-rectilinear. The corridor is a transitional zone between lawyers and the clients, a longitudinal space dividing service areas from offices. The colours and materials distinguish the surfaces by their use. As the dark grey zone identifies the service functions, the wooden surfaces cover storage spaces.

The slim, linear ceiling lighting guides visitors between the spaces, which are organised hierarchically according to use. Lighting fixtures align with the tectonic of the design language. Depending on the viewers’ perception, the folded metal plate is a horizontal line or a non-orthographic object, like the mathematical concepts of referential relationships and covariance.

All the forms are meaningful in dynamic perspective, not just from certain angles. This is hard to represent in two dimensional media - it needs to be experienced spatially. Inside a conventional orthogonal office structure, the space represents the inherent qualities of law institutions through its non-linear yet unbiased and strong tectonics. The tensions between the orthodox rectangular volumes and oblique surfaces, along with the contrast between cold and warm materials, also embodies the occupant’s intrinsic professional values.
