Does anyone know the correct way to indicate a named terrace of houses within a street, please? The case in question is a 'terrace' of semi-detached houses, so although I could tediously put an address to each house, I opted to enclose them in a landuse=residential and name that, but suspect this is not the preferred method.

The technique I have come to favour is roughly as follows:

Create a building for the complete terrace, tag this building_name=Blabla Terrace.

Afterwards there are a number of choices:

  • You can either split the building using the JOSM terracer plug-in and retain the original building, or do it manually in which case you will have to recreate the original building.
  • Remove the superfluous building_name tag from the individual building=house elements.
  • Add address information to the house polygons. Option 1: to remove the building tags from these just leaving polygons providing the address, and this seems to work for most purposes - thanks to Dee Earley for this idea); Option 2: use the building_part relation to identify the individual properties in the terrace.

Here's an example where I have not yet terraced the terrace: Peel Villas.

A much simpler way is to represent the terrace as a address interpolation way in which case you can just name the way as here: Robroy Terrace.

JOSM of course will protest loudly about overlapping buildings, but much of the information (other than addresses) which one may want to associate with houses in a terrace belong to the terrace (date of construction, no of levels, roof type, building material, builder, architect, etc).

The whole process requires more refinement, but in some places I think accurate information is not merely a nice to have, but essential. For instance Fford Garth Isaf (Lower Garth Road) in Bangor, Gwynedd ( has many terraces, with houses numbered in the terrace. Conventional sequential house numbering has been introduced relatively recently (also on Fford Garth Uchaf, where houses just used to have names).

A mapper near here does as you do. e.g.

I generally either put the terrace name in the housename field and the number in the terrace in the housenumber field, or I put both in the house name field. So in SK53's example I might have

addr:housename = 1 Peel Villas addr:street = Gregory Boulevard

None of these solutions feel entirely satisfactory. In the UK you might need to worry about "dependent thoroughfares"

Actually the houses in Peel Villas all have standard Gregory Boulevard addresses (surveyed but not entered into OSM).

In my home town in the UK which I have mapping they are many terraces and other residential areas that have a different name to the road that they sited along how I have solved this problem (though not sure if htis is the right one) is to draw a "living street" along the main street or road then naming the living street by the name of the terrace. Or I have drawn a single terraced house and named it for the whole terrace.
