The original, highly decorated, cast iron sewage vent pipes are still intact and visible on the exterior of the building.
Cabragh House School
From 1906 until 1927 Amber House housed a "Boarding and Day School for Girls and Little Boys" known as Cabragh House School and operated by the Hornby family from Ireland. Edwardian photographs of both the scholars and the school have been preserved.

Because New Zealand has had for the last two centuries (and continues to have) the highest ultra violet exposure levels of any populated region on earth it is extremely rare to find used (as opposed to unused roll) examples of Victorian Wallpaper in New Zealand that have not faded badly from exposure to sunlight.
This remarkable state of preservation is rather ironic considering that Nelson yearly vies with its neighbours Richmond and Blenheim for claiming the highest number of sunshine hours in the country, with an annual average total of over 2400 hours. You can see the raw data here:

There has been speculation that, because deep below Amber House are separate beds of shale and sand, these strata have acted like a naturally occurring analogue of the earthquake resistant base isolators of the Parliament House in Wellington to reduce the incidence of short periodicity lateral waves at Amber House during earthquakes.
The evident resilience of this old chimney means that it is even possible that it pre-dates the 1893 magnitude 6.9 Nelson earthquake that moved the spire of Christ Church Cathedral in Nelson nearly a metre out of the vertical plane.
Old English Walnut tree
Amber House has the oldest English Walnut tree (Juglans regia) in the South Island in the back garden. Although old, this venerable tree is relatively small since, when it was originally planted, it would have been only yards from the original shoreline and on very sandy soil with the roots lacking an adequate water supply. This desiccation has resulted in an almost Bonsai like effect.
