SHANGHAI, Jan. 21 (UPI) -- Shanghai company WinSun claimed it 3-D printed a five-story apartment building and villa using a 500-foot-long printer.

The apartment is undecorated, but the 11,840-square-foot villa is luxuriously decorated and on display in Suzhou Industrial Park.

It was printed using a special formula for patented "ink" comprised of construction waste such as concrete, fiberglass, sand, and a special hardening agent. It allows them to use a high amount of recycled material.

The process reduces construction waste by 30 to 60 percent, production times by between 50 and 70 percent, and labor costs by between 50 and 80 percent.

The same company claimed to print 10 houses in 24 hours in April.

Chinese company 3-D prints apartment buliding

The utility of 3D printing continues to grow with leaps and bounds and the most recent invention, the worlds first 3D-printed apartment building, is on display now at Chinas Suzhou Industrial Park. The building is the pet project of Shanghai-based company WinSun Decoration Design Engineering Co. who have been working hard in the industrial construction 3D-printing market.

The building stands five-stories, encompasses a 1,100 square meters (11,840 square feet) and is constructed from 3D-printed materials made from recycled materials combined with fast-hardening cement. The size makes this the tallest 3D printed structure in the world.

The large pieces are fabricated by this printer at WinSuns facility, shipped and assembled on-site. The components are complete with steel reinforcement and insulation to provide with official building standards.

The 3D printer array is monstrous in size compared to consumer models: 6.6 metres high, 10 metres wide and 40 metres long (20 by 33 by 132 feet). The printer was invented by WinSuns CEO and founder Ma Yihe who has brought the firm notoriety already by printing 10 houses in a day during March 2014.

Images and descriptions of the printing process from WinSuns website show the printer producing pieces by laying the frame and sides of the hollow walls and then filling it in with a zig-zag pattern of material to provide reinforcement. The company says that design is controlled by a CAD design template and a computer controls the extruder to lay down the final product.

According to WinSun the 3D-printing process saves between 30 and 60 percent on construction waste, can decrease production time between 50 and 70 percent and labor costs by 50 to 80 percent. The villa cost the company around $161,000 to build.

The company expresses an interest in using 3D-printing technology to reduce waste by using recycled materials and improve safety for workers and the environment, by exposing workers to less noise and hazardous materials.

WinSun wont release how large the architectural pieces it can produce are, however hopes to use its technology to facilitate even larger construction projects in the future including on bridges and skyscrapers.

China super-sizes 3D-printing with worlds first printed apartment building

A Chinese company has set another world first in 3-D printing living space.

WinSun, the company that used 3-D printed materials to aid in constructing 10 houses in a period of 24 hours in March 2014, has constructed the worlds first 3-D printed apartment building. The five-story building made its debut in Suzhou Industrial Park in Suzhou, China, alongside a separate, 3-D printed 11,840 square foot villa.

Printing large parts for buildings also calls for a large 3-D printer to accomplish the feat. WinSun used, according to CNET, a proprietary 3-D printer measuring 132 feet long, 33 feet wide, and 20 feet tall to print each part of the mansion. The 3-D printer uses a material created from ground construction and recycled industrial waste to construct the parts. Once the pieces were printed, the assembly of the building occurred at the site, with the addition of steel reinforcements and insulation to meet Chinas building codes.

The company, however, does not want to stop there. WinSun, CNET reports, aims to use its 3-D printing technology to tackle even larger projects, including bridges and skyscrapers.

Worlds first 3-D-printed apartment building debuts in China

Office space being built in the Bakery Square 2.0 complex in the East End's booming Penn Avenue corridor is almost fully leased, and developers are setting their sights on tenants for a second office building.

Because we're so close to Carnegie Mellon, Pitt and other local universities, we feel there is a lot of pent-up demand for companies who want to come to Pittsburgh to locate here, said Gregg Perelman, managing partner of Shadyside's Walnut Capital Partners.

O'Hara-based software maker Autodesk Inc. plans to lease about 15,000 square feet and employ 65 people in the six-story office building, scheduled to open this fall in Bakery Square 2.0. Internet search giant Google Inc. will anchor that building, leasing about one-third of the space.

By moving to Bakery Square, we will be in closer proximity to both established and startup companies in this area, Autodesk spokesman Noah Cole said.

Cole said the location will enable Autodesk to work more easily with CMU and Pitt researchers and tech developers, along with potential interns from the universities.

The brisk pace of securing tenants for the first building prompted Walnut Capital to start seeking tenants for the second one earlier than anticipated, Perelman said. The second building would be about the same size as the first, Perelman said.

I suspect we will be breaking ground on another office building ahead of schedule to keep up with this unbelievable demand, Perelman said.

Kevin Acklin, Mayor Bill Peduto's chief of staff and chief development officer, said he isn't surprised.

Walnut is doing so well because the site is so close to the talent base that Google, Autodesk and others are looking for, Acklin said.

Acklin pointed to transportation improvements in the area, including development of the East Liberty Transit Center near Penn Avenue with improved platforms and accessibility for transit riders using the Martin Luther King Jr. East Busway.

A Chinese company has successfully 3D printed a five-storey apartment building and a 1,100 square metre villa from a special print material.

Caixin

While architectural firms compete with their designs for 3D-printed dwellings, one company in China has quietly been setting about getting the job done. In March of last year, company WinSun claimed to have printed 10 houses in 24 hours, using a proprietary 3D printer that uses a mixture of ground construction and industrial waste, such as glass and tailings, around a base of quick-drying cement mixed with a special hardening agent.

Now, WinSun has further demonstrated the efficacy of its technology -- with a five-storey apartment building and a 1,100 square metre (11,840 square foot) villa, complete with decorative elements inside and out, on display at Suzhou Industrial Park.

The 3D printer array, developed by Ma Yihe, who has been inventing 3D printers for over a decade, stands 6.6 metres high, 10 metres wide and 40 metres long (20 by 33 by 132 feet). This fabricates the parts in large pieces at WinSun's facility. The structures are then assembled on-site, complete with steel reinforcements and insulation in order to comply with official building standards.

Although the company hasn't revealed how large it can print pieces, based on photographs on its website, they are quite sizeable. A CAD design is used as a template, and the computer uses this to control the extruder arm to lay down the material "much like how a baker might ice a cake," WinSun said. The walls are printed hollow, with a zig-zagging pattern inside to provide reinforcement. This also leaves space for insulation.

This process saves between 30 and 60 percent of construction waste, and can decrease production times by between 50 and 70 percent, and labour costs by between 50 and 80 percent. In all, the villa costs around $161,000 to build.

And, using recycled materials in this way, the buildings decrease the need for quarried stone and other materials -- resulting in a construction method that is both environmentally forward and cost effective.

In time, the company hopes to use its technology on much larger scale constructions, such as bridges and even skyscrapers.

BYRON CENTER, MI Apartments and condominium projects came roaring back in Ottawa County during 2014, fully recovering from a collapse of the market that dates back to 2008, according to Builder Track Reports.

Single family home starts also showed continued strength in the Lakeshore area, according to Builder Track Reports, which follows home building activity in West Michigan.

In Ottawa County, builders started construction on 443 apartment units, mostly to serve Grand Valley State Universitys student population in Allendale Township. Thats compared to a total of 52 units started in the previous four years.

CHICAGOThe downtown multifamily market continues to set records. Related has just sold OneEleven, its 60-story apartment tower at 111 W. Wacker Dr. to Heitman for over $328 million. At $651,000 per unit, Related officials say it is the highest amount ever paid for a Chicago apartment building.

The previous owner of the site at Clark St. and Wacker Dr. had already begun construction on the proposed 90-story Shangri-La hotel and condominium tower when the onset of the recession halted construction. Related took over the site just a little over three years ago after the partially constructed base of the building had sat untouched for several years. Related redesigned the site as 504 units of luxury rental housing, redeveloped the property and began leasing last spring.

The acquisition of OneEleven in 2011 came at a significant discount to replacement cost making it an ideal fit for our fund management platform, skill set and our fully integrated execution strategy, says Justin Metz, managing principal of Related Fund Management, an investment adviser. In just three years, we were able to bring new resources, develop a marquee core asset and maximize value for our partners and investors.

By assembling a world-class design and construction team, we were able to take a distressed property along Chicagos riverfront that for years was symbolic of the recession and transform it into a luxury apartment tower that helped put the Loop on the map as one of Chicagos top residential neighborhoods, says Curt Bailey, president of Related Midwest.

New York-based Handel Architects designed the glass-sheathed tower and Kara Mann Design did its interiors. It opened in July 2014 and features a mix of studio, convertible and one-, two- and three-bedroom residences and more than 30,000-square-feet of amenity space. The property has proven popular and tenants now occupy more than 80% of the units.

The remarkable response, reflected first by the quick pace of leasing and, now, the record-setting sale of the building, validates our vision for this site and the Loop as a whole, where a number of new apartment developments are following in the footsteps of pioneering projects like OneEleven, Bailey adds.

Related Midwest will soon break ground on a 67-story residential tower at 451 E. Grand Ave. and also plans to develop 400 Lake Shore Dr., the site of the former Chicago Spire project.

INDIANAPOLIS (WISH) The investigation continues after a big fire destroyed a luxury apartment building in Fishers.

Investigators believe it could take months before theyknow the exact cause.The fire happened at The Flats in Fishers Marketplace early Tuesday morning. The building was under construction and vacant at the time. Two other buildings, including a clubhouse onsite were not affected.

Several construction workers scoped out the fire damage Thursday afternoon, just two days after a massive fire broke out at the Flats.

I see a building thats unsafe, said John Mehling, Fishers Fire Department. Due to the weight thats on the building now.

The multi-million dollar building is one of three buildings on The Flats property. It has been under construction since last year, and was scheduled to open April.

This could be one of those situations to where the investigators just dont have enough evidence to say one way or another that this is the cause, said Mehling.

The building still stands, but investigators said the freezing temperature is turning everything inside the structure into ice.

The problem with the ice right now aside from what its doing to the structure itself, is that its incasing whatever evidence thats in there, said Mehling. So to protect the evidence, we have to be very careful removing that ice from around it.

Mehling said it could take months to find out the cause of the fire because of the extensive damage, but theres a possibility, that the cause could be undetermined.

Apartment owner Peter Davis has been locked in battles with hisbuilding's developers for years and warns new laws that come into force on Thursday will cause an "even worse hell for home owners than we've been through".

Mr Davis and his wife bought an apartment in a new block on Sydney's upper north shore seven years ago, only to pay tens of thousands in legal fees to fix construction defects that required replastering the pool, a new ventilation system, as well as fireproofing issues discovered only last year.

Legal changes are "draconian", Sydney home owners say. Photo: Louie Douvis

"We [the owners' corporation] have paid millions in legal fees and expert reports that would stand up in court. Under the new laws, we would have had to pay for the repairs ourselves. These new laws are completely inappropriate," Mr Davis said.

Owners of new apartments will now have only two rather than six years to get developers to foot the bill for building defects, once the Home Building Amendment Act takes effect.

A spokesman for Fair Trading NSW said the new laws, passed in September last year, were designed to strengthen the consumer protections and address issues in construction industry by changing the licensing system for tradespeople.

These will increase penalties for practitioners and companies with a track record of issues, as well as changing payment structures to ensure fewer major defects.

Home owners will be able to access the previous six-year warranty only in relation to flaws that put the building or property at risk of falling down or becoming uninhabitable.The definition for "major defect" is new in the act.

But the peakbody representing strata owners has described the new defect rules as "draconian" and told Fairfax Media the changes would have serious and far-reaching consequences because many issues take years to emerge.
