Comments update: Isay Weinfeld's first New York project is the latest in a string of luxury developments changing the face of the city – but some readers think the rush to build high-end apartments is destroying the Big Apple's local communities. 

New luxury: Weinfeld's Chelsea development will feature two 11-storey buildings, including a fitness centre, an indoor pool and a secluded garden. Units are expected to start at $2 million (£1.3 million).

"Quelle surprise," wrote Dean. "Another luxury residential building in New York City – that's exactly what Manhattan needed to ensure diversity in the demographic."

"Does New York City have any type of housing other than luxury?" added Võ Duy Kim, while Luke said that the city's appetite for high-end housing should always be "balanced against the needs of wider communities".

Others felt Weinfeld's "simple and elegant" design represented New York's move away from "flashy" architecture. Read the comments on this story »

Drone delivery: Amazon unveiled a video showing the latest version of its self-piloted delivery drones at work this week. But could health and safety laws thwart the online retail giant's plan to roll out the technology?

"Governments are making it so difficult to fly any type of drone near or over people," wrote Nicole. "Amazon will be taking a huge risk unleashing these in the wild."

Abduction could also be a problem, according to readers. "What if I hold on to that thing when it wants to take off again?" asked Lisa. But optimists championed the project's potential to reduce carbon emissions.

"This could be so much more sustainable than convenient delivery methods," concluded Kevin. "It's one small step closer to a zero-waste society." Read the comments on this story »

Memorial architecture: architect and sculptor Mirosław Nizio is building a mausoleum to commemorate victims of Polish village massacres during the second world war. But some readers think his design is too bold to be a place of contemplation.

"This feels like everything to do with architecture and almost nothing to do with the massacre," said Michael Whittle.

"Sometimes subtlety goes a long way with projects like these," agreed Camden Greenlee.

"So what would you propose – another piece of jagged something from the Libeskind conveyor belt?" retorted CharlesCU. "It looks to me like an entirely appropriate and empathetic place." Read the comments on this story »

Good intentions: the poor design of refugee camps remained a hot topic this week, as Venice Architecture Biennale 2016 director Alejandro Aravena described the use of emergency tents as a waste of money.

Concerned Citizen's response to the article provoked a strong reaction after declaring many recipients of permanent housing solutions "show no gratitude or respect".

"So what then, give them nothing?" responded a commenter calling themselves MB. "I can't see any other way to resolve the situation than to treat these emergency camps as proper townships and develop them accordingly." Read the comments on this story »
