Rose Garden Cottage is situated on Library Road between the Library and the Mews, just north of the Rose Garden. Once the site of the gardener's root house of the Dunsmuir family estate, then a gardener's staff room and equipment storage shed, the Rose Garden Cottage is now an administrative center for RRU.  It is also a showpiece of environmental sustainability.  The new foundation was largely hand dug in order to preserve the roots of nearby trees. Soil compaction was also minimized to avoid disrupting root systems. The foundation itself was made from a mixture of recycled glass and sand, which is less expensive than traditional aggregates and helps create a demand for recycled products. The manufacturer will recycle the carpet when it is worn out and the wood flooring is made of recycled by-products.
