Readers could not hold back their excitement after plans were unveiled by Kengo Kuma and Associates for an aquatics centre framed by black pyramids in Copenhagen, in this week's comments update.

Making a splash: readers gushed over renders of Kengo Kuma's planned Water Culture House that is planned as part of COBE's regeneration of Christiansholm in Copenhagen harbour.

HeywoodFloyd approved: "Interesting and thought-provoking design. Also a very good schematic presentation, concepts are presented with just the right mix of clarity and ambiguity. Excellent work from this guy, as usual."

"A sense of cave diving, wonderful," wrote Harmanto Nguyen, in reference to Kuma's design.

Rot took their praise to the extreme: "Clear and spiritual. Elemental and modern pseudo-archaic. Masterful."

"This will be incredible. Kuma is a material master," agreed Archi.

Noa had just one question: "When will it be built?"

Miles Teg felt the plans could not be any more current: "Another great design from a great master, including a duck-face making, selfie-taking, render girl no less!"

But the renders did have one fault according to this reader.

Waste of space: the cost of a stay at Texas-based startup Orion Span's planned luxury space hotel, which will be marketed at £6.7 million for 12 nights, left some readers bemused this week.

"Don't you just hate these projects that pander to the very rich? It's stupid and absurd!" fumed Chris Brown.

"To be fair, this is probably the most beautiful way of wasting your fortune," countered Zea Newland.

Sascha took a more optimistic approach: "Some of the very rich will go to space. My only hope is that this trip, the unique experience and the view down on mother earth will change them and their point of view."

"The survival of our species hinges on developing a spacefaring infrastructure and a self-sustaining off-world presence," Chuck Anziulewicz chimed in.

"The survival of our species hinges on us not trashing the Earth," fired back Aaron.

For one reader, the price was not the main factor on whether they would visit.

Airbed: Airbus revealed designs that would convert aircraft cargo compartments into passenger sleeping quarters, including beds and meeting rooms, but readers were quick to debunk the idea.

"No way these images reflect how it will look in reality," pointed out Robin.

"Where are the windows!?" exclaimed Hah.

"I can't imagine how much it would cost to sleep in one of those bunks," cringed Kawiman636.

But Colin MacGillivray left to the defence of the concept: "Less than a flat bed in business class probably. This is a great idea for flights taking off after 10 pm when the passenger just want 8 hours sleep."

This reader had thought of another way the quarters would help him get some sleep on his next flight.

Pink slip: Martin Brudnizki Design Studio renovated the infamous London members' club Annabel's with the aim of capturing "the spirit of English eccentricity" got a mixed response from readers this week.

"This represents everything that is wrong with hospitality design," sighed Michal.

"If Brexit was an interior," added The Huey, cheekily.

Chris MacDonald was left flummoxed by the project: "It's so over-the-top and gaudy, every bone in my body wants desperately to hate it. But I don't! It's so ugly it's brilliant; is that even a thing?"

"Much of it is 'bad taste', but it would be so much fun to be there" admitted Karol B.

This reader was definitely comfortable with the overhaul of the club.
