What you can object to
An objection only counts if it is about a material planning consideration. Loss of value, a private view, competition or who the applicant is do not count. Most Hounslow applications are extensions and lofts, dormers and roof extensions, so these are the grounds that come up most here:
Also: character of the area, trees, noise and disturbance, traffic and parking, construction disruption, drainage and flooding. Then write it up with the objection letter guide or the template. Numbers alone rarely decide it: see how many objections stop an application.
