Renfrew–Collingwood has seen a large amount of development in the past two decades, much of it coming thanks to the construction of the SkyTrain and its related stations. Three stations - Nanaimo, 29th Avenue and Joyce-Collingwood - were constructed on the 1986 Expo Line, while the Millennium Line brought the Renfrew and Rupert stations to the area. Joyce-Collingwood Station has turned into the centre of a booming residential area with condominium developments still being built around it; this area has encompassed the former Collingwood town centre, which continues to be a popular shopping area. To the north, Grandview Highway has drawn some large "big-box" stores and turned into an economic engine for that portion of the community. Also in that area is the busy Vancouver Film Studios operation. Much of the heritage of both Renfrew and Collingwood has been pushed aside by progress and redevelopment, but certain heritage sites still remain - for now. The Carleton Elementary School, at the southwest corner of Kingsway and Joyce, is one example of those early days of development. The 1896 building is still standing, along with several other school buildings from the development of the area. Renfrew–Collingwood is also the home of Vancouver's only remaining craftsman style firehall, Firehall 15, at the corner of Nootka and 22nd avenues. Currently, the City of Vancouver is researching the feasibility of preserving this building, as well the historically significant 2400 motel on Kingsway, though the future of both sites is very much in doubt. In 2007, the City of Vancouver announced the Norquay Village Neighbourhood Centre Program, one of several neighbourhood centre programs it plans to implement as part of its Eco-Density initiative. If the program goes ahead, much of Renfrew–Collingwood will be re-zoned from single-family homes to duplexes, with areas along some of the busier streets zoned for rowhouses. The idea is to increase density and encourage the development of shopping centres along Earles and Rupert streets. The plan is controversial: the city claims that density is better for the Earth's environment, but many residents do not want their neighbourhood to lose its single-family home character. The commercial area is anchored by a Safeway supermarket adjoining which is the Eldorado Motor Hotel, and features a wide array of businesses, including a variety of ethnic-owned and ethnic-themed businesses. The area includes Kensington Gardens, the new master-planned community comprising three residential towers, a supermarket, retail shops, Asian-inspired
