Cambridge
Cambridge isn't a particularly big city yet takes centre stage for the main university, which it's iconic for. The city by itself only has a populace of 125,000 but pulls in a good amount of tourism with the river attraction as well as other activities. There's a selection of housing within the city as well with older and contemporary homes, so no matter if it's insulation or renewable technology, be sure to keep your Cambridge property up-to-date.
