The key bond=* can be used to nano map the bond of a brick wall. This can be interesting for historical research or 3D rendering of the building/ wall.

How to map

Important note: Do not analyse the bricks between windows, as the brick layer mostly tried to fill the space as best they could; focus on the areas above and below windows or gable ends instead.

Add building:material=brick or building:facade:material=* to a building or wall=brick to a free standing wall.

Add the key bond=* and one of the following values (list might not be complete, because these depend on the regional tradition of brick layers). It is possible to add several bonds to a building, separated by semicolon.

raking_stretcher_bond		Courses of stretchers with every second course set off by a quarter stretcher.	Danish: Løberforbandt Dutch: Klezoorverband

flemish_bond		Alternating stretchers and headers. The earliest example in England is Kew Palace (1630s).	Dutch: Vlaams verband French: appareil flamand

english_bond		Also known as Common bond in the UK, dating as far back as Tudor times. Strongest bond, and therefore often used for foundations. Alternating courses of stretcher bond and header bond.	Danish: Blokforbandt Dutch: Staand verband French: appareil anglais Spanish: aparejo inglés
block_bond		Very similar to English bond, but every stretcher course starts with a header.	French: appareil français
cross_bond		Derived from block bond, but every second stretcher course is set off by a header. Each header has either a stretcher above or below and a joint below or above, whereas in block bond, it always has a stretcher above AND below. Decorational crosses can be formed by differently coloured bricks. Sometimes differentiated between English cross bond and Dutch cross bond, depending on whether English (size) bricks or Dutch (size) bricks were used..	Danish: Krydsforbandt German: Kreuzverband French: appareil en croix ou croisé
scottish_bond		A course of headers followed by five courses of stretchers. See also below.	French: appareil américain
american_bond		A course of headers followed by (at least 5, but up to) 9 courses of stretchers. Called 7-course American bond up to 9-course American bond in the United States of America.	French: appareil américain
sussex_bond		Three stretchers, followed by a header, followed by three stretchers etc. In each course, a header is resting centered on a stretcher.
dutch_bond		A course of headers followed by a course of alternating stretchers and headers.	French: appareil hollandais Spanish: aparejo holandés
silesian_bond		Two stretchers and one header with the headers overlapping from course to course.
gothic_bond		Alternating stretchers and headers with headers overlapping and stretchers overlapping from course to course. Called staggered Flemish or zip bond in the US of A.	German: Polnischer Verband or Gotischer Verband French: appareil gothique
rat_trap_bond		Used for hollow walls. Looks similar to flemish bond, but bricks are standing on the stretcher face.
???		Stretcher bond with gaps for ventilation or decoration.	French: appareil à claire-voie Spanish: aparejo palomero Portugese: aparelho aberto
opus_spicatum		Ancient Roman and medieval bond (Wikipedia). Courses of diagonal bricks, sometimes broken by courses of stretchers.
stack_bond		Stretchers not overlapping.
irregular_bond		No discernible pattern, but certain rules apply.	French: appareil sauvage
dog_tooth_course		Also dog's tooth or saw tooth . Merely decorative, not for supporting walls (hence not a bond). Bricks are either laid turned 45° with the corner to facing out or every second header in a header bond set off inside the wall.	American English: Hound tooth course
