I've finally added some lot numbers to the map in my area. Took a little walk around some random streets and was able to figure out the number pattern. That allowed me to fill in ever address in the village.
Hopefully when the Nominatim gets updated we'll be able to search for lot numbers in Charlestown.
Actually if you look at the Bing overhead shots of the area you'll notice many houses in there not accounted for. It's actually more of a conceptualized lot scheme than the actual one. You'll notice at Enid's Barber Supplies there's a W and E component to the lot number. The area between Adelaide and St. Stephen's is one lot width, the others are two and each lot may have up to 4 main divisions.
But THAT is something for another time. :-)
P.S. Zoom in on the map to see Charlestown

Why are you guys so structured? In Belgium, the buildings are just like tumour cells. osm.org/?lat=50.93983&lon=3.06938&zoom=15&layers=M
I have to check each house to see what number it has.
Currently, I'm trying to draw the buildings, so that I can use walking papers to complete the numbers and check the building outline.

If you zoom out and look at the water channels in Guyana you'll see why. Basically there's miles and miles of rice and sugar cane fields. They're all rectangles with ditches surrounding them and canals here and there feeding them. It seems basically once in a while the govt. acquires a large tract of land and proposes a "housing scheme". It gets divided up into lots and they sell them off cheap. So every block has a ditch around it, most houses have a small bridge to the front door and villages are boundaried by waterways.
Once I figured that out the whole naming scheme and numbering scheme started to make lots of sense. Unfortunately many of the housing schemes don't have street names so someone may say they live at "Lot 275 Diamond" and you have to go around asking for directions the whole time. Usually you call someone on the cellphone as you start to get to their area.
Look here (osm.org/?lat=6.75321&lon=-58.17252&zoom=15&layers=M) the lots are the same size as the nearby blocks. I could spend years tracing just the waterways. :)
