The Comalat house is a modernist work in Barcelona's Eixample, built in 1909-1911 by the architect Salvador Valeri i Pupurull. It is considered an example of late modernism for its decorative tendency to take the ornamentation to every corner. It is a work protected as a Cultural Property of Local Interest.

The main facade, which faces Diagonal Avenue, is symmetrical and more formal. It is made of stone and on a background of smooth stone the sculptural work above the windows and on the corbels of the balconies stands out. The whole is topped off with a pediment with oval openings and reliefs of garlands that has a rococo air dome covered with green glazed ceramics.

On the other hand, the rear facade, which faces Córsega street, less importantly, it has a much less formal and more free and original treatment, with irregular tribunes, roller shutters, stained glass and mosaics occupying the window sills, on artificial stone bases of different tones with organic shapes and parabolas of the Gaudienne type. The ceramic decoration, very abundant on this facade, is by Lluís Bru, who also did part of the interior decoration. One floor retains the original modernist decoration.
