Original design sketches for the front elevation and first floor plan of a rather large department store with shopping and offices on second and third floor, designed in the American "Richardsonian Romanesque" style. I used massive lintels over the doors and windows, a variant, in contrast to the more common huge semi-circular arches more often seen. This style of building still exists today in every American city, small or large, as commercial and public buildings, and, sometimes as grand luxury homes. To say they were well-built is an understatement. Some are primarily grey stone of some type, some are tan sandstone, but many are brownstone style in dark reddish brown sandstone with matching brick. This building design is a commissioned piece so there were stringent requirements on the size and shape of the ground plan and interior layout.
Technique: Hand-drawn pencil studies in small scale, 1/16"=one foot, front elevation toned to terracotta with software, floor plan reduced to half size.
That is Richardsonian. There is a great architectural statement of his in Buffalo, where I grew up. It was the State Mental Hospital, looks like a gothic castle. On the other end of that Avenue is a church designed by him as well.
Yes those buildings are outstanding because they are still standing. One big plus for a city whose economy bottomed out forty years ago is that there is no reason to pull down an architecturally significant building to make room for a parking garage. So, you have Sullivan, Richardson and Wright buildings. Your blueprints are great.
