Marino borders other northside areas such as Fairview, Donnycarney and Clontarf. Marino roughly encompasses the area within the boundaries of Sion Hill Road, Gracepark Road, Philipsburgh Avenue (north of Lynch's), Malahide Road and Shelmartin Terrace. His book, To-morrow, a Peaceful Path to Real Reform (1898), was reprinted in 1902 titled Garden Cities of Tomorrow.

Howard's idea came from 19th-century writings which inspired him to build the opposite of the general urban conditions that existed at the time, hence building the 'Garden City', to be 'a perfect combination of rural and urban living'. The design of the new Marino development was heavily influenced by the Garden City Movement, which originated in the United Kingdom with Sir Ebenezer Howard. The initial development featured around 1,300 concrete-built houses. It was built, in a planned form, on former grounds of Marino House, in an area between Drumcondra, Donnycarney, Clontarf, and what became Fairview. The windows have blacked-out panels to hide the fact that the interior is a complex of rooms, not a single chamber.Marino ( Irish: An Mairíne) is an inner suburb on the Northside of Dublin, Ireland. The towering front door is a sham – a much smaller panel opens to reveal the secret interior.

A variety of statuary adorns the outside, but it's the amusing fakes that are most enjoyable. But instead it is an extravagant convoluted maze: flights of fancy include chimneys for the central heating that are disguised as roof urns, downpipes hidden in columns, carved draperies, ornate fireplaces, beautiful parquet floors constructed of rare woods, and a spacious wine cellar. The exterior of the building, with a huge entrance doorway, and 12 Tuscan columns forming a templelike facade, creates the expectation that its interior will be a simple single open space. He also came home with a big love of the Palladian style – hence the architecture of this wonderful folly. It was built in the mid-18th century for the Earl of Charlemont, who returned from his grand tour of Europe with more art than he could store in his own home, Marino House, which was on the same grounds (demolished in the 1920s). When it's operational, entrance is by guided tour only the last tour is 45 minutes before closing. Unfortunately it's closed for essential maintenance, with no reopening date confirmed at the time of research. It's not the roulette-wheel kind of casino but rather the original Italian kind, the one that means 'summer home' (it literally means 'small house'), and this particular casino is one of the most enchanting constructions in all of Ireland.
