Talk:List of most expensive buildings

Antilia, South Mumbai
I just removed this from the top spot. The original edit introducing it was from 106.209.175.178, but that arbitrarily replaced Abraj Al Bait, and included an unreferenced, $15Bn number, which does not agree with the $2Bn estimate over on Antilia (building)). Still if $2Bn is accurate, it should be on this list, and the claim to "world's most expensive private residence" might be noted. I think this table needs to have the ranks removed, and the inflation adjustment done by macro. — Preceding unsigned comment added by Talkie tim (talk • contribs) 17:06, 8 February 2019 (UTC)

Palace of the Parliament
The Palace of the Parliament in Bucharest should definitely be added. Construction cost of $3bn. — Preceding unsigned comment added by 91.190.162.157 (talk) 18:41, 16 June 2017 (UTC)

AU Parliament
I get the strong sense that Parliament House, Canberra should be on this list. $1.1Bn AUD was around $710m USD in 1990 (I don't have data for 1988 forex) - it was the most expensive building in the world at the time. Going by US inflation rates (i.e. converting at 1990 rates, but from '88 to '12) the cost would be ~approx $1.4n today. Alternately if I go by AU inflation since 88 and convert to USD in 2012, it becomes $2Bn. --120.144.133.24 (talk) 01:49, 11 July 2014 (UTC)

-Its now listed as 1.1 billion, but its supposed to be in USD, while the source is in AUD. 23.240.131.64 (talk) 01:20, 27 February 2015 (UTC)

Revel should be added. 2.4 billion. — Preceding unsigned comment added by 50.14.74.174 (talk) 23:58, 12 September 2014 (UTC)

What about the new karolinska hospital i stockholm sweden? 1.87 billion total building cost (has since increased by about 7 percent), 6130 usd/sqm, floors 10. estimated to be finished 2017 — Preceding unsigned comment added by 192.44.242.18 (talk) 06:33, 5 December 2014 (UTC)

Adelaide Myer Centre
Built in 1988-1993 at a cost $1billion AU. That seems to calculate to about $1.97billion AU now and should probably be on the list. https://en.wikipedia.org/wiki/Myer_Centre,_Adelaide Romen (talk) 10:37, 25 April 2015 (UTC)

Royal Adelaide Hospital
Construction 2012-2016, not yet open, estmated at 2.3 billion AUD. however this was last stated around 12 months ago: https://en.wikipedia.org/wiki/Royal_Adelaide_Hospital

Need to improve clarity of definitions and accuracy of data set
There appear to be some discrepancies in and between the two lists which should be resolved. Among others:

a) The Shard is listed as the most expensive building at the time of completion (2012) at a price of US$ 3.9 bn. It does not, however, feature in the main list of most expensive buildings. Is this an oversight?

b) Marina Bay Sands is listed as having a total construction cost of US$ 5.50 bn although the main MBS article reports US$ 4.7 bn including the cost of the land. Are all the cost of construction figures including the land price?

Suggestions:

1. Column "Built" should be renamed to "Completed" - may also include a column "Started"

2. Open to more suggestions on how to improve the page...

what does "at time of construction" mean?
It really is difficult to work out what this metric is. — Preceding unsigned comment added by 58.96.110.98 (talk) 10:36, 9 September 2014 (UTC)

The list misses some very important entries
ie.: The Palace of the Romanian Parliament, with an estimated cost of over 4 billions USD (as of 2006) it would be on number 3. I find that it would be hard to miss the most expensive and largest administrative building in the world. Correction required. Roth66 (talk) 19:02, 11 October 2014 (UTC)Roth66

Where are all the big industrial and energy complexes?
- Three Gorges Dam $26 000 000 000 - Itaipu Dam $19 600 000 000 (1975-1984 dollars) - Guri Dam $2 500 000 000 (1963-1978 dollars) - Xiluodu Dam $6 200 000 000 - Flamanville 2 NPP may exceed $10 000 000 000 and its completion is unsure - Olkiluoto 3 NPP may be almost $10 000 000 000 and also its completion is unsure (the original price tag was €3 000 000 000) - Chernobyl New Safe Confinement $3 000 000 000 (est.)

See https://en.wikipedia.org/wiki/List_of_megaprojects for more big construction projects.

What does a building mean?
E.g. ITER is not just a reactor. It's a facility containing multiple buildings.

Same goes for Olkiluoto 3. "Airports are excluded as their construction cost includes runways and systems" but also power plants include systems. Nuclear plants often consist of several buildings, cooling water inlets and outlets or cooling towers, sea walls or dikes, external power generators (with buildings), electricity substation(s), road and even rail connections (for fuel transportation). The cost might include training of employees, all kinds of government costs (nuclear safety etc.), some maintenance contract, testing, fuel, etc. — Preceding unsigned comment added by 78.27.94.0 (talk) 00:30, 6 August 2020 (UTC)

The Vienna General Hospital should be on the list
It is the most expensive European hospital. Total construction cost: 45 billion Schilling (3.3 billion Euro, 3.88 billion dollars) https://en.wikipedia.org/wiki/Vienna_General_Hospital#New_AKH — Preceding unsigned comment added by Chrimas1 (talk • contribs) 09:49, 3 October 2017 (UTC)

The scope of this list is unclear
What is a building and why are most megaprojects excluded? Oneiros (talk) 00:36, 4 February 2019 (UTC)

Clarification of the scope would aid in deciding whether alterations like this: https://en.wikipedia.org/w/index.php?title=List_of_most_expensive_buildings&diff=885060166&oldid=884054848 should be reverted ­– the reason given for the deletion is laughable anyways considering industrial buildings like Gigafactory 1 are listed as well. — Preceding unsigned comment added by 93.237.72.151 (talk) 18:57, 7 March 2019 (UTC)


 * Indeed, what about TSMC Fabs then? Each is estimated to be $10B+. Utopiah (talk) 23:00, 6 January 2023 (UTC)

Misleading figure for New Karolinska Hospital
I'm new to WP so I don't want to do anything wrong, but I will make a suggestion: The figure of 6 bn as production cost of the New Karolinska Hospital is misleading. The source is an op-ed in a Swedish newspaper, and not any kind of official figure of itself. There has been considerable controversy surrounding the construction of this hospital, especially regarding its cost, so I think this op-ed is cited for biased reasons. The op-ed itself refers to an article/investigation by a reputable newspaper, Svenska Dagbladet, here: https://www.svd.se/nya-karolinska-tio-miljarder-kronor-dyrare-att-bygga. That article cites the constructions cost at 23.5 - 24 bn Swedish kronor (SEK) including furnishing with medical equipment at 5.5 - 6 bn. The other costs are extraneous, such as prior demolition and rezoning of the land where the hospital is built, and costs incurred due to diversion of patients etc. They are NOT construction costs. We still do not have an official final tally of the costs, but a more accurate number should be 24 bn SEK or 2.58 bn USD, including equipment. Rgrankvist (talk) 12:30, 12 February 2019 (UTC)
 * Hi Rgrankvist! According to the article in SvD the cost is at least 25 bn sek, (2.7 bn USD). I cited the article and moved down the project to place 11, with the cost "c. 2.7 bn USD. St.nerol (talk) 16:21, 22 April 2019 (UTC)
 * This was changed back in an anonymous edit. I will reinstate the more established figure, this time without the cost for equipment, since it seems that this list aims to cover pure construction costs. (I came here again since noticing that the Swedish Social Democratic Party has made a campaign site based upon the running total cost of NKS and its high placement in this list.))

Harbours excluded?
"Airports are excluded" - and "harbours" as well? It seems for me like that. Then we should add this. --F.Blaubiget (talk) 09:51, 25 December 2020 (UTC)

The Great Mosque of Mecca speculation
The cited source for the first item of the list, The Great Mosque of Mecca (Expansion Project), says that the figure is from anonymous sources and that "no figures can be confirmed". So I propose removing this item. –St.nerol (talk) 21:14, 17 July 2022 (UTC)
