Minnesota architect Josh Lewandowski has started a blog where he'll post one meaningless architectural diagram every day for a year (+ slideshow).

Since 7 September, Lewandowski has been publishing a single drawing to his Pointless Diagrams blog every day, and intends to continue for a whole year.

"I started the blog because for as long as I can remember I've always drawn and doodled 3D sketches that have an unapologetic dearth of meaning," Lewandowski told Dezeen. "I'm doing it because of my sincere belief that setting aside time to doodle useless stuff is extremely useful."

The drawings depict imaginary structures and architectural scenarios, and some of the diagrams also feature directional arrows. "I like that people I've shown them to see different things based on their own experiences," he said.

"I draw my inspiration from architecture, furniture, engineering, geometry, cereal boxes, Lego instructions and Etch A Sketch memories," explained the designer. "I always use pen and ink because an early art teacher told me erasing is for wimps."

The original drawings are made in pen and ink on buff acid-free paper and are available for purchase from Lewandowski.

Lewandowski studied Art and Architecture at the University of Minnesota and a Masters of Architecture at Yale University. He is the founder of furniture design firm Nordeast Industries.

Other illustrations featured on Dezeen include Toby Melville-Brown's drawings of impossible architectural structures and Tom Ngo's Architectural Absurdities series featuring a building made of stairs and an impossible lighthouse.

Here's a full description from Lewandowski:

Pointless Diagrams

I started the blog because for as long as I can remember I've always drawn and doodled 3d sketches that have an unapologetic dearth of meaning.

Whether it was in a 6th grade English class, during a Peter Eisenman lecture in grad school, or when I should have been CADing while employed at Robert A M Stern Architects; I was drawing.

The sketches are usually meaningless and aesthetically could be described as equal parts Draw Squad and James Stirling.

I draw my inspiration from architecture, furniture, engineering, geometry, cereal boxes, lego instructions, and Etch A Sketch memories. I always use pen and ink because an early art teacher told me erasing is for wimps.

This blog chronicles my attempt at a year-long endeavor to draw one diagram a day, because of my sincere belief that setting aside time to doodle useless pictures is extremely useful.

They appear meaningful without actually being helpful. Some might seem to reference real things or show some sort of relationship between things, but that is merely coincidental. Enjoy.
