This is just a compilation of construction cost of different hotels and buildings in Ethiopia. It's hard to compare the figures below since the exchange rate of ETB has changed considerably in the last 20 years. Some figures are written in USD while some are in ETB.
For example, Sheraton Addis cost around 200 Million USD on 1998 which at the time will be less than 1.4 Billion Birr if the exchange rate of ETB was 7 against the USD. At the time of writing this post (October 2015), the exchange rate of ETB is around 21 compared to USD. So, Sheraton addis might cost 4 Billion Birr or more right now. (October 2015)
