It would probably cost about the same due to UK housing layout.

The 30A star hub could go under the hall floor (upstairs), with a run
to each room and drop to rooms below. Unfortunately it would require a
newly developed junction box using L-N-E bus-bars to handle 8-9x 4mm
sized cables. It would be useful for central inspection and testing,
but buried under a floorboard it could well end up forgotten and
screws can work loose.

Such "star spiders" are sometimes used for complex lighting circuits,
built up using modern enclosures and DIN rail terminals. Easy central
inspection and testing, neutral at every light switch etc.
