The Cement Factory was discovered in 1973, it was an abandoned cement factory and partially in ruins, comprised of over 30 silos, underground galleries and huge engine rooms; Ricardo Bofill bought it and began renovation works. He identified the program; The Cement Factory was to be used as architectural offices, archives, a model laboratory, and exhibition space, an apartment for him, as well as guest rooms and gardens. He defined the space by demolishing certain structures, cleaning cement, exposing previously concealed structures and creating the landscape architecture by planting various plants such as eucalyptus, palms, olive trees and cypresses; renovation works lasted nearly two years — via Yatzer

Perhaps the most famous racing Ducati of all time is the 750 that took Englishman Paul Smart to victory in the 1972 Imola 200 race. And with a machine as iconic as that, you’re going to get people wanting to copy it. One such man is German Hajo Barth, and to make life easier, the starting point was his SportClassic Paul Smart 1000. Ducati already did a pretty good job in emulating the original Paul Smart bike, but Barth wanted something even closer—not only in looks, but also performance. So he took his bike to the dealer Ducati Rhein-Sieg in Waldbröl, and they set to work — via Biek EXIF

The 4-valve Guzzi motor has to be one of the most imposing powerplants of all time. And Jasper Mulder, a marine contractor currently working in Nigeria, was so smitten he chose his 1993 Moto Guzzi Daytona on the strength of that motor alone — via Bike EXIF

Larry Houghton of Lamb Engineering in the UK keeps a low profile on the custom motorcycle scene. But he’s got an unerring eye when it comes to building show winners: his latest creation took the top trophy at Custom Chrome’s recent European Bike Show. ‘Son Of A Gun’ is based on a BSA Gold Star, although there’s little left of the original. The engine is a 1951 ZB-model single—which makes it 499cc, I’m assuming—and according to Larry, it’s an ex-racing engine. (Which makes sense, because BSA offered different compression ratios and camshafts to cater for the sporting fraternity.) The gearbox is thought to be from a BSA M20 military motorcycle, and that’s where the vintage authenticity ends — via Bike EXIF
