Each courtyard garden has been individually styled — one with an Italian theme and one Santa Fe style for instance. Formal in design, the main plantings consist of mondo grass borders surrounding buxus, murraya and may bush hedges. There are plantings of bougainvillea, white balsam, lillypilly, standard podocarpus, sesanqua camellias, agapanthus, liriope, acanthus and hydrangea.

With appropriately positioned screen plantings the gardens were designed and planted not only for pleasure but also for privacy. Peter's other objective was to fill the place with light and have each room looking out onto a green space. Each courtyard is enhanced with ornaments, sculpture, and decorations fitting with the style and individuality of each room. Peter says the bedroom courtyard is based on and Italian garden. It is adorned with box hedged and large topiaries and as often found in formal gardens, a central feature.

Peter's love of the garden extends from outside in, with indoor plants decorating the hallways and botanical artwork adorning the walls. But it doesn't stop there — Peter's garden has also overtaken the park next door.

Originally a children's 'concrete' playground that was very rarely used, the park is now an extension of the Wannan house garden. With the assistance of Parterre Garden (a local landscape design business) Peter approached his local council about 10 years ago with designs and plans to transform the idle parkland into a passive seating area for locals and passers by.

The council accepted Peter's proposal and undertook the main construction work of the garden including paving and implemented a minimal planting scheme. Peter then set to work filling the garden with additional trees and shrubs that have since grown to form a glorious garden. People in the neighbourhood or guests who can admire it from Peter's house can enjoy this secluded little oasis.

Peter has been honoured for his efforts by winning Woollahra Municipal Council's annual award in both 1998 and 1999 for best garden and courtyard.
