In this week's comments update, readers are discussing a skinny house with exposed concrete walls in Japan, designed by local studio IGArchitects.

Named 2700, the 2.7-metre-wide home was built on a long and thin site left over following a road expansion in the city.

"Doing more with less is always commendable" 

Several readers were impressed with how the design utilised the space available. "Doing more with less is always commendable," commented Jb.

"Another example of how strict codes and limited space force an architect to create something brilliant," wrote Duckusucker. "Japanese home architecture is easily the most inventive and attractive in the world."

Puzzello was also full of praise, writing "great house – this is urban density that only the Japanese know".

However, not everyone was convinced. Jack Woodburn called it a "concrete cave-like bunker abused by 24/7/365 roadway noise" before warning it was "likely at some point to be struck by a distracted and/or drunk driver".

Although they did acknowledge that it would be an "interesting take on a tiny home if located more sensibly".

"This is heartbreaking, one of my favourite buildings in any form or typology"

Commenters also reacted to the news of a fire at the 17th-century Børsen building in Copenhagen, Denmark, which caused its iconic dragon tail-shaped spire to collapse.

"You'd think these 'relics' would be protected by a 'tasteful' sprinkler system," proposed Dik Coates.

Meanwhile, in a comment that was upvoted seven times, Niles reflected "amazing how these historical buildings catch fire during construction works".

However, Applkonvurt was more preoccupied with the damage caused by the fire, lamenting "this is heartbreaking, one of my favourite buildings in any form or typology".

Later they added that "the three intertwined dragons that made up the spire were one of the coolest things you'll see on such an old structure – hopefully they can save it (or reconstruct it)".

"I doubt there is even demand to fill one fifth of this tower"

Another story causing traction in the comments section this week was the news that a height variance request for what is set to be the tallest skyscraper in the US located in Oklahoma City has been approved.

Most commenters were not impressed. "What a colossal waste of resources – I doubt there is even demand to fill one fifth of this tower," condemned Franky four fingers.

"I hope they can't afford to build the clutter around the base – keep it classy OKC," wrote Steve Hassler.

Ervin Schömer was similarly incensed "I think this is a stupid investment in Oklahoma!" They went on to argue that "there can be better ways to use this enormous sum of money for better purposes!"

"Nobody cares about skyscrapers anymore," added Jb.

Nevertheless, Apsco Radiales chipped in with words of encouragement, exclaiming "go for it, Oklahoma City!"
