The Kumar family are long-time residents of an older neighbourhood of a major city. They inherited their home from Ms. Kumar’s parents. Their own family is now grown up and gone, and Mr. and Ms. Kumar enjoy the pleasures of the quiet and beautifully maintained back garden—that is, until the past few months. The neighbours on one side of the Kumars sold their property about a year ago, and the new owners have shown the Kumars their plans for the property. The plans involve demolishing the home and building a much larger house, very close to the boundaries of the property. Because the building will be three storeys high and because of its size and location, all afternoon sun will effectively be blocked from the Kumar’s garden. Moreover, they will lose their privacy. The Kumars are distraught. They are also very concerned about the noise and disruption from the demolition and construction. Finally, they have noticed that the large and noisy air-conditioning and heating units will be placed adjacent to their property, right beside their bedroom wall. Assuming that all these changes are within the local planning rules, what are the Kumars’ rights? What factors should the Kumars consider before launching a legal action?
