These buildings are designed as models for drawing or modelling at school. They are great for drawing a floor plan, front elevation, side elevation and oblique drawing.
The dimensions of all models are multiples of five millimeters so they can be easily measured by your students without a caliper.
You can scale up the models, so the teacher has a bigger one for showing things to the students. (On the last photo you see prints with 100% and 300%.)
The author marked this model as their own original creation.
