Crazy paving is a means of hard-surfacing used outdoors, most frequently in gardens. Paving stones of irregular size and shape are laid in a haphazard manner sometimes with mortar filling the gaps between.
The method originated in ancient Rome.{{cite book |title=Paths and Walkways: Simple Projects, Contemporary Designs |last=White |first=Hazel |author2=Plut, Matthew |year=1998 |publisher=Chronicle Books |isbn=0-8118-1429-7 |pages=[https://archive.org/details/pathswalkwayssim0000whit/page/80 80] |url=https://archive.org/details/pathswalkwayssim0000whit |url-access=registration |quote=Crazy paving. |accessdate=2008-07-18}} The design was half-way between mosaic and sectile and primarily used chippings of white and colored limestone.{{Cite book|last1=Ling|first1=Roger|title=Roman Painting|publisher=Cambridge University Press|year=1991|isbn=978-0-521-31595-1|location=Cambridge, UK|pages=19|url=https://archive.org/details/romanpainting0000ling|url-access=registration|via=Internet Archive|access-date=January 22, 2023}} It sets up the paving stones without geometric grid so that they are used as they naturally break as opposed to being cut in geometric shapes.{{Cite book|editor-first1=Jan |editor-last1=Birksted |title=Relating Architecture to Landscape|publisher=Taylor & Francis|year=2005|isbn=0-203-35260-2|location=London |pages=83 |doi=10.4324/9780203352601}}
Crazy paving became popular during the 1970s and the use of just one type of stone is among the modern updates.{{Cite book|last=Young|first=Chris|title=Encyclopedia of Landscape Design: Planning, Building, and Planting Your Perfect Outdoor Space|publisher=DK Publishing|year=2017|isbn=978-1-4654-7078-2|location=London|pages=352–353}} Today, the hard-surfacing approach is also used as a means to recycle paving materials.{{Cite book|last=Lawrence|first=Mike|title=Masonry and Plastering|publisher=Crowood|year=2011|isbn=978-1-84797-351-1|location=Marlborough, UK|pages=75|url=https://archive.org/details/masonryplasterin0000lawr_d3s1|url-access=registration|access-date=2023-01-22|via=Internet Archive}}
