Coilliot's factory and warehouse were located to the rear of his house, and therefore the façade held a double purpose, both decorating the front of his home and advertising his business.

The Coilliot House is constructed of bricks and cut stone, with decorative elements in wrought iron, ceramic and enamelled lava.

[2] While only the Coilliot House itself is a registered building (including its interior), the block of flats and warehouse also feature Art Nouveau details deemed worthy of preservation.

For instance, elements of the apartment block's façade at 13/17 rue Fabricy and its ceramic fireplaces were added by the DRAC to the national heritage register in October 2011.

[3] However, the house's Art Nouveau interior decoration and furniture can be seen in a short clip shot in 1983 and now accessible on the INA website.
