My first impressions are favourable. There are contraints though, as the design guide acknowledges:

> WikiHouse is intended for buildings of up to 3 storeys. This covers 95% of all buildings, and allows gentle density neighbourhoods of up to around 75 dwellings per hectare.

> The main constraint on height is not gravity, but wind. In high winds, lightweight structures are more prone to slight lateral flexing, which is not allowed within most building codes. Further structural research and testing is ongoing.
