I was part of a small group of about eight people guided around the house and its grounds. The arrival at the house is beautifully staged - it's invisible from the road, and comes into view as you reach the bottom of the driveway.
You can see in the image below that parts of the steel are in need of a coat of paint. Inside, the ceiling is showing evidence of dampness. The house is in the care of the National Trust for Historic Preservation which, given the current economic climate in the US, is looking more and more to private donations to maintain the property. This is not to say the house is falling into disrepair - far from it, it's just that the Trust is having to prioritise a schedule of works at the property. Proceeds from tours assist with these activities.
This view below is from the home's lawn on the promontory, looking back into the living area. Johnson had the trees regularly trimmed to enhance the view.
This view looks through the living area, featuring furniture by Mies van der Rohe, including a daybed specially designed for Johnson which subsequently went into production around the world. (Mies' glass house, known as the Farnsworth House, is located near Plano, Illinois, and was completed in 1951.)
There are other buildings on the property, including Johnson's studio and a small building at the entrance to the estate which was the last structure he designed. You can see shots of all of them on the official website of the house. If you're in New York, do book ahead and go and see this (the visiting season runs from May through to November - on October 20 New York architect Charles Renfro, our international judge in our Home of the Year award 2010, is leading his own tour of the house - tickets for this are also on the Glass House website). It's a magical architectural experience, and an insight into what seemed to be a pretty magical and enthusiastically lived life.
