What is SkyCity? 

SkyCity is a platform within Broad Group which wants to take this new material and other ways of construction to the next level and that is why we have launched a series of biannual design competitions called SkyCity Challenge. This year’s challenge “The Future of Housing" is meant to find new proposals for construction and design that are as innovative as the material itself. Remember BCORE is hollow on the inside and this brings us more opportunities in creating new hybrid solutions for construction.


What is BCORE?

BCORE is a new innovative building material Broad Group has just invented. It is made of stainless steel, composed of two sheets connected by a firmly welded tubular system, used in space technology. Since we are concerned about the impact of the current construction methods on the environment, we have decided to create this new material from scratch, securing low CO2 emissions, very high durability and overall recyclability. Zero waste impact.

What is a BCORE CTS Slab?

The BCORE CTS Slab is the name that receives the piece of BCORE cut 12 meters long by 2 meters wide.

What are the measures of a standard BCORE CTS Slab?

The standard BCORE CTS is 150mm thick. Understand that these CTS slabs are welded in giant ovens in bulk for the maximum efficiency. The standard CTS Slab can be used for floors, structural walls, exterior walls with insulation and crossbeams. We are able to manufacture slabs with different thicknesses as well, but for the purposes of this challenge, please use the standard CTS slabs. This standard slab can be cut into different sizes for the purposes of your project. In case you want to use CTS Slabs also for the interior walls; the thicknesses are 40mm, 60mm or 100mm.

What is the price of a BCORE CTS Slab?

The standard BCORE CTS Slab (12m x 2m x 0.15m) cost is 38,400 RMB or 5000€.

Does the rock-wool insulation come with the CTS Slabs?

All the insulation material is already preinstalled in the factory together with the plumbing and wiring (based on your preliminary designs) and consecutively shipped mounted within the slabs to the construction site. Unlike the rock-wool insulation inserted into the slabs the standard BCORE CTS Slabs does not come with plumbing and wiring solution by us. If you choose to insert them within these panels, please provide us with a scheme of your solution. However, it is not mandatory.


Must the design concern a housing prototype to be replicated and multiplied in several units so as to obtain a building, a tower to be used as a residence, or the project must relate to the single housing unit?

Is up to the participant. However, we are looking for the rentability of this project in the near future. Exploring models like co-housing, for example, will be totally acceptable and favorable.

Is there a specific place for the location of the design?

No. The participant is free to choose the place of the project. As the goal of this project is to achieve a complete solution of a modular prefabricated set for housing, the location is irrelevant. 

Should be items, such as bathroom units or doors be included in the container's space as well?

Yes. Doors, windows or kitchen/bathroom units such as sinks, toilets, or showers should have their space in the container. Remember that we are designing a product to be delivered to the customer for a final assembly.

We are open to hear any new design ideas or strategies that could resolve any space issues occupied by these elements in the container, for example by encouraging the future clients to use easily accessible and standardized units available anywhere around the globe.

Applies the same with furniture?

No. The furniture does not. 

Are there any limitations or standards in the number of square meters of the floor-plans according to our design?

No, just make sure that the volume of all the dissasemblable pieces of your designs, fit into a single standard shipping container (40 feet, 40´ × 8´ × 8´6")


Can I participate individually?

Yes, individual proposals are accepted. The registration can be also done by a single participant.

Can a participant be in two different groups with different proposals?

Yes. A participant can be in two different proposals since each of these proposals has a different code. Just make sure you use a different email address for it to avoid confusion.

If I want to modify the registry by adding or removing any of the participants, can I do it?

Yes, no problem, just do it before October 1, 2019. If you do, please send us an email with the ID registration code we have sent you to avoid the confusion.

Is the contest only open for architects?

Not necessarily. The contest is open to any creatives related to the contest anywhere around the world, you can be an industrial engineer, civil engineer or just a big fan of off grid sheds. We are hoping to receive the best ideas, related to the field of design and construction.

Students and graduates are welcome to participate as well.

Can I send more than one proposal?

Yes, but each proposal must have a different registration code.

What happens if the winning team can't attend the SkyCity 2020 residency at BROAD Town?

The winning team has a month to confirm their visit to China. This can be done by all the members or at least (1) of them. In case no one from your team can attend the residency, we will invite the team from the second place.

Who would cover my travel expenses to and from China?

Broad Sustainable Building Ltd. and SkyCity will make sure that the winning team will receive 2000 USD as travel allowance in local cash, once the team successfully arrives to the Airport in Changsha.
