The more sun a house gets, the higher its value, according to a new study which suggests developers might need to compensate neighbours when they block sun.
Motu Economic and Public Policy Research Trust has released what it calls the first research carried out anywhere in the world to specifically evaluate the extra value house buyers put on extra sunshine hours.
Arthur Grimes, a senior fellow at Motu and co-author of the study, said there was a direct correlation between more sunshine and higher values and the study was precise about how much extra value is added.
"Direct sunlight exposure is a valued attribute for residential property buyers, perhaps especially in a cool-climate city such as Wellington. However, natural and man-made features may block sunlight for some houses, leading to a loss in value for those dwellings," the study said.
"No study in the urban economics literature has estimated the value that house buyers place on sunlight when purchasing a property. We do so, finding that each additional hour of direct sunlight exposure for a house per day [on average across the year] adds 2.4 per cent to a dwelling's market value. This estimate is robust to a variety of specifications that investigate whether the value is conditional on other factors relating to the characteristics of the house or its suburb."
