In the 1970s, an urban development plan aiming at improving people’s living environment was introduced by the Hong Kong Governor Lord Crawford Murray MacLehose. The continuous growth in industrial export turned Hong Kong into one of the major international entrepots and earned it the reputation as one of the Four Asian Dragons. Simultaneously, demand for construction materials was bolstered by a massive array of infrastructure projects.

Building on a solid foundation with advanced technology and facilities, K. Wah’s Anderson Road Quarry became a key supplier of high quality quarry products and concrete which were deployed in a number of infrastructure and public housing projects in Hong Kong.

The improvement in the livelihood of the public led to an expansion in high-end property market. Seizing on the opportunity, K. Wah pioneered the development of luxurious villa-type houses in Hong Kong with the Black's Link Villas in Deep Water Bay in 1974. The superb location and captivating furnishings set a benchmark of luxury properties in Hong Kong. One of the eight villas was sold at a record-breaking price.

Reaching the end of the decade, Hong Kong had become a famous “shopping paradise” for tourists from around the world with an influx of over two million travelers paying visit to the Pearl of the Orient each year. Yet, Hong Kong still lacked comprehensive hospitality support. Always at the forefront of trends, Dr Lui joined hands with the world renowned hotel group Holiday Inn to build his first five-star hotel. In 1979, he acquired a land parcel in Tsim Sha Tsui East for HK$68 million and spent another HK$300 million to build the InterContinental Grand Standford Hong Kong (previously known as the Holiday Inn Harbour View) which officially opened in 1981. It was one of the very few five-star hotels in Hong Kong under a franchise system. Embracing the motto of customers first, K. Wah has been keen on nurturing professionals in hotel management along the years, which had also become the backbone for its success in the entertainment & leisure business in Macau later on. The pool of talents also contributed greatly to the local tourism industry.
