The “relational volume” of the house features an “Hemisphere”, recalling Houston’s space enterprises modernity, with useful diameter 8.40 m, connected by an “octagon transition” ring to a “cuboid” 8.5x8.5x2.40 m . The “Hemisphere” hosts main floor ( +0.60 for living) and mezzanine (+3.20 for dining; the “cuboid” hosts the ground level (-1.90).
The smallest “envelope” for the necessary “volume” should achieve best thermal relations in the local environment and best personal relations in the resident family.
Thermal performance is assured by:
double reflective, crash proof, glazing; sun tracking and insulating shells, with louvers ;
minimum heat transmitting envelope and solar direct radiation interdiction;
thermostat at lower level.
Unity or at least contiguity in family life can be supported or encouraged by a living space without internal partitions with the attraction of full angle perception of local environment.
Symmetry of design fits extension of lots from 33’ x 90’, with any orientation and location with regard to street.
The house adapts to neighbourhood by reflecting on dome glasses the image of its surroundings.
Excavated soil (except polluted stratum) will be reused on site. Design is for later recycling of most materials: dome aluminium and glasses, concrete modular units, copper conductors and pipes.
Cubic/spherical construction stands better storms and earthquakes.
Gas burning boiler, Utilities’ meters and AC splits are located in a “satellite”.
Ventilation is achieved by opening windows and a top louver.
Low costs are possible for relevant off site construction.
Design follows IBC as amended by the City of Houston.
