There are four main thoroughfares that comprise Centennial Park, the suburb. They are Lang Road, Martin Road, Robertson Road, and Cook Road. Of these Martin Road is the only one that has not segued into a major thoroughfare around the Sydney Cricket Ground and associated sporting facilities. Of course, this meant that it retained its 'exclusive' air.
Although the type of material used to construct the housing was mandated (to exclude the hoi-poloi) the style of building was not prescribed. Hence, along these four thoroughfares can be seen styles such as Federation, Arts & Crafts, Victorian, Old English, and Californian Bungalow. Being a member of the hoi-poloi, the thing that strikes me the most is the size of the blocks, the hedges to keep out prying eyes, and the landscaped gardens.
Having large houses of a specific style which are registered on the National Estate (its heirs and successors forever!), means a hefty annual bill for maintenance. Some of the houses are starting to look tawdry as a result.
