There is indeed on Erra, on the central planets of Pleiadians/Plejaren, also some larger cities with multi-story houses, however no apartment blocks are to be found in the form of multistoried buildings or skyscrapers or the like, where the human beings must live packed together. Between the individual residential buildings oneself finds expanded park- and garden-plants, which with clean attached footpaths are looked after. Also is to be found well-regulated on central point landing points for personal- and special-flight-bodies, the entire overall ownership corresponds and can be used by everyone according to demand. Roads of any kind are completely unknown, because Pleiadians/Plejaren use absolutely no land-vehicles. Thus all populated areas are purely pedestrian zones, where no noise, no traffic chaos and no environmental pollution through exhaust gases etc. are given. The majority of the Pleiadians/Plejaren prefer, to live not in cities but rather apart from these in the green, i.e. in the country, and indeed in single family houses, which exhibit a hemispherical or spherical form and a minimum diameter of 21 meters.

For the main thing the building material consists of very resistant metal alloys or of plastic, which are gained from the soil, mainly from sand. This plastic is similar to our silicone. Each single family house stands by itself however on a fruitful property, that as a rule is a hectare (10000 square meters [2.471 acres = 1076.391 sq ft] = 100 x of 100 meters [328 ft. x 328 ft.]) in size. The group houses, i.e. families on these properties themselves strive, to be as self-sufficient as possible, accordingly each dwelling e.g. possesses its own water and power supply, which are dependent on no public system. For the domestic requirements each family or other housing unit on these properties plant their own gardens of fruit, vegetables, herbs and flowers, which in each case is with great joy worked on, nurtured and cultivated. Entirely completely every fertile area of land is used for natural food cultivation and therefore made arable and cultivated.

A homestead is to such an extent built and sized, that it provides a place for a family of five and no more, because the guidance issued maximum number of descendants amounts to no more than three children per wife. A guidance of the 'High Council', that, like all other guidance, is followed. For peace preservation reasons etc. parents-in-law should not live together with their standing-in-partnership, i.e. marriage-bonded children in the same household; a rule, which is consistently uniformly kept. Parents-in-law can however live on an adjacent property in their own single family house, themselves should however in no wise interfere in the concerns of their children, when these are married or grow out of the education age. Also this is a rule, like many others also, that is completely kept. At the age of 14 to 16 years the children leave the parents' house, in order to be educated in small groups and in the community of the same age ones.

Since the man is polygamous in the contrary to the predisposed monogamous woman, this is taken into consideration by Pleiadians/Plejaren in the form, that one man can marry up to four wives, which also prevents the prostitution, which among these extraterrestrials already from time immemorial is no longer given. When in accordance with this rule one man therefore has two, three or four wives, then they are often resident in a so-called quad, which consists of one correspondingly great property and of two, three or four single family houses, therefore each wife has her own refuge and consequently her own habitation and her own household.

Regarding the buildings is to still be mentioned, that these are created absolutely earthquake-proof against the most severe vibrations. Also they are absolutely protected against lightning bolt and elementary storms etc. All buildings, also when they are still thus large, are seamlessly manufactured from one piece, have as a rule only a few stories and possess a spring system, a type of floatation chamber.
