The final addition to the house was a wing built between 1890 and 1891.

At first, only one wing of the building was built.

In 1921 a new wing to the building was built.

By 1917, only the front and the north wing had been built.

The new wing is much longer than the one built in the 1950's.

The present west wing had been built in its place by 1729.

The west wing and south front were built in 1842-46.

Another wing was built to the west and opened in 1977.

Currently the new wing of the school is being built.

The east wing of the building was built in approximately 1550.
