Welcome to OSM.

Mapping new developments is trickier without aerial imagery, but there's 
quite a bit you can do to make it more accurate than guesswork.

  * if you're mapping the roads use the GPS to walk down their centre,
    if it's safe to do so, of course)
  * Takes *lots* of photos. Videos are even better
  * If there is something already mapped in OSM Field Papers may help:
  * I found that many new estates have a certain amount of conformity.
    Try offsetting a copy of the road centre lines to use as guidelines
    ensuring buildings equidistant from the road & the same width

To map larger buildings you can walk walk around it taking waypoints 
with a GPS whenever you're in line with the plane of a building's side. 
These points can then have a way drawn with their opposite number to 
create the buildings outline. Make sure you're far enough away from it 
to avoid GPS interference.
