Dutch couple are Europe’s first inhabitants of a 3D-printed house:
The south Netherlands property, made by 3D printing a specially formulated cement through a nozzle on a robotic arm, is inspired by the shape of a boulder – a design difficult and expensive to construct using traditional methods, writes The Guardian.
While properties have been partly constructed via 3D printing in France and the US, the Dutch home is said to be the first “legally habitable and commercially rented property where the load-bearing walls have been made using a 3D printer nozzle.”
It is the first of five 3D-printed houses planned by construction firm Saint-Gobain Weber Beamix for a plot of land by the Beatrix canal.
“It is beautiful,” said owner Elize Lutz. “It has the feel of a bunker – it feels safe,” added co-owner Harrie Dekkers.
The house consists of 24 concrete elements printed offsite before transported by lorry and placed on a foundation by Dutch building firm Van Wijnen. A roof and window frames were fitted, and finishing touches applied.
Details of the construction are visible in the final product, for example, the point at which the 3D printer’s nozzle head had to be changed after hours of operation is visible in the pattern of the new bungalow’s walls, as are small errors in the cement.
By the time the fifth of the homes is built – with three floors and three bedrooms – it is hoped construction will be completed wholly on-site and various other installations will also be made using the printer, further reducing costs.
The 3D printing method is seen by many within the construction industry as a way to cut costs and environmental damage by reducing the amount of cement that is used.
People’s odds of loneliness could fall by up to half if cities hit 30% green space targets:
One in four Australians feel lonely on three or more days a week, write Thomas Astell-Burt (University of Wollongong) and Xiaoqi Feng (UNSW).
However, their recent study published in the International Journal of Epidemiology has found that adults in neighbourhoods where at least 30% of nearby land is parks, reserves and woodlands have 26% lower odds of become lonely – compared to peers in areas with less than 10% green space.
For people living on their own, the associations were even greater – in areas with 30% or more green space the odds of becoming lonely halved.
This is good news for cities around the world such as Barcelona, Canberra, Seattle and Vancouver, which have targets of 30% green cover.
It’s even better for residents of the City of Sydney and the City of Melbourne, with targets of 40% green cover by 2050 and 2040.
Successful products are often followed by copycats. Over the past year we have become aware of an increase in reproductions of the Linea range attempting to create a similar aesthetic at a lower price. This can compromise the overall durability and environmental credentials of projects being delivered, affect ongoing maintenance requirements, and in some instances pose a risk of injury to the public. The design of Linea is deceptively simple while delivering exceptional attention to detail. Details matter not only for beauty, but also for providing durability, and safety, that will last decades. Linea strictly uses the highest quality and sustainable materials, has passed rigorous strength tests, and is designed for longevity, with easily replaceable parts. The product range is the result of hundreds of hours of research and development …

Toronto swaps Google-backed ‘smart’ city plans for people-centred vision: Canada’s largest city has moved towards affordability, sustainability and environmentally-friendly design in a new vision for the Quayside waterfront – a year on from parting with Google-affiliated Sidewalk Labs. Waterfront Toronto launched an international competition in March to secure a new development partner for the Quayside lands, to build “a sustainable community for people of all ages, backgrounds, abilities and incomes.” The Quayside development will provide “market and affordable housing options for individuals and families. It will offer opportunities for aging in place, including the supports and amenities that will allow seniors to live independently. Inclusive economic development opportunities will create jobs and spaces for business owners that reflect Toronto’s diversity,” they write. The call for new proposals comes nearly a year after the Sidewalk Labs partnership was called off, a “stinging defeat” reports …
