Minnette conducted a number of studies which laid down some interesting concepts and ideas. She was interested in the sociology of the tourism and the culture reciprocity of tourism.
She had a concept flexible planning and an additive / subtractive architecture. An integrated plan of indigenous, environmental and ecological elements. The integration with the landscape for a traditional symbiotic relationship between architecture and the environment. A feeling of being free from 'herd' philosophy.
The integration of village arts and crafts as village workshops in the resort village.
With meditation gardens 'Sakman Uyanas'.
Internal circulation would be on foot, by peddled trishaws or bicycles.
The micro climate to be enhanced by pools and canals of water around the building. Lotus marsh gardens wherever there was land below spill level.
A wooded landscape with buildings amidst it.

The outcome was the SigiriyaHotel Development. Even though mock-ups were built, the project never got off the ground. Many of the ideas developed for Sigiriya were subsequently used by other developers, especially at Sigiriya and Habarana.

In 1982 Minnette settled down to work on the much needed 'Art Centre' in her home town kandy.

She wanted it to be a large interactive space where a number of activities could take place with a strong symbiotic relationship of arhitecture and entertainment. The excavated area to the rear formed a natural amphitheatre, and the 150 years old building adjoining the site became a focus to the new tradition. A kandyan village setting in the choice of trees, plants was a pleasing foil to the maligawa (temple of the sacred tooth) and and cross the lake the malwatta Vihara (reidence of the high priest of the sest). Minnette willed the 'Art Centre' to be the most characteristic and living illustration in the kandy region of a contemporary kandyan Architecture.

Many levelled kandyan flat tiled roofs and symbiotic indigenous features, thorana (gateways), midulas (open courts), mandapas (pavillions), rangahala (space for dance and music), avanhala (refectory), were all part of her design for the Arts Centre.
