Market Research on construction 3d printers that can print houses

I am interested in purchasing a CONSTRUCTION 3D printer, an example construction 3D printer is The P1 model from BetAbram and the 3d printer from Winsun. I require you to source several different brands/models and answers the following questions with answers coming directly from the manufacture/suppliers of each model.
The questions to be answered are;

the price for each model?
the constraints of the each model? in regards to the maximum size unit it can produce
can the model build several units and connect them together ?
what inputs does the each model use ? (software ? material? power ? )
how much human intervention is required through the entire process ?
how quickly can the each model build units ?

a minimum of 5 models need to be included in the research with emphasis on models cheaper than £100,000.The example models can be used in the research.

Proof of correspondence with manufacturer must be shown (screenshot of email will do)

a suggestion to get some of the information is to simply go to each manufacturer's website and fill in the contact form asking all relevant questions and waiting for relevant answers for each question. However this is a suggested method and all task detailed above should be finished on completion of the job.
