A proliferation of malls was part of that 'internationalisation.' Lots of global brands are found in these malls. Add the setting up of the Nairobi International Financial Centre.
The arrival of elite hotel brands such as Raddison, Hilton, Crowne Plaza, and Sheraton, among others is part of that 'internationalisation.'
Hilton has left me perplexed: They closed the CBD hotel but have opened 'Hiltonlets' on the outskirts of the city.
Does that show how the CBD has lost its lustre? It seems that the CBD will soon be left to the government.
Second heritage
Why not turn all these empty hotels and offices into apartments? Who said you must commute to work?
The second heritage is national, being the capital city, government officials from politicians to civil servants live there. That aggregation of leaders gives the city a special status.
Every five years, a new crop of leaders makes the city their home.
Most never leave after that. Students graduating from universities make it their home too. The city is always sucking in new people. Few leave either through natural attrition or giving up. Paradoxically, devolution made the city more attractive.
How do you stand out among the many counties? Make Nairobi your home! Lots of money made in the counties - legally or illegally - eventually makes its way back to the city.
That creates demand for goods and services and hence the high prices, from rent to a cup of tea. Noted, the county cars plying Nairobi streets every day? Did I hear some governors excluding Sakaja operate or used to operate from Nairobi? The third heritage is local, Nairobi despite its national and international status has ordinary Kenyans as the majority, making up over 60 per cent of the population.
That is the group that Mr Gachagua is vouching for. They were either born there or have immigrated. Mr Sakaja sees the other 40 per cent, the expatriates, the civil servants, the sophisticated entrepreneurs, or retirees.
They want peace in their homes and no noise from bars. They could probably afford wine in the house. Do you recall one city official saying the city is for whiskey and not chang'aa takers?
The rest, 60 per cent, the hustlers who live in the slums or pseudo slums or high-rise apartments do not notice the noise. They make a living out of it. They have kiosks or vibandas. And taking alcohol is part of their entertainment. There are no playgrounds or open spaces.
The triple heritage of the city is further illustrated by road networks. Some use the expressway, away from the public, with no bumps, roundabouts or police.

The rest are caught in the traffic jam commuting in matatus.
Others walk home or take bodabodas. Some never leave the city and are homeless. The local heritage is further complicated by immigrants who come to the city but keep their traditions, from language to food and religion.
Schools also reflect triple heritage. We have international schools, public schools and private schools.
That's replicated in medical services with waganga (witchdoctors) at the lowest level. Even churches have heritages ending with street preachers.
Economic classes
All these heritages have been cross-pollinated by colonial set up which still echoes to this day with estates reserved for certain social economic classes.
Seen signboards like "no matatus allowed on this road?"
Our leaders often represent one of these heritages or are hostages to them. Money or lack of it defines the heritages which rarely merge and are hardened over time.
We come to accept them and at times admire them. We work hard to shift from one heritage to the other, with pride. Some observers like former Murang'a Senator Kembi Gitura have suggested one way to disentangle this heritage is to make Nairobi a national territory.
That could demand a constitutional amendment. Was that in the Building Bridges Initiative (BBI)?
If we copied or adopted the US constitution, we could adopt its amendments. The constitution is not the holy Bible or the Koran, it can be changed to suit the changing circumstances. The three heritages will always contest, often using politics to advance their economic agenda. That is the reality our leaders must accept.
