Default How to model the house

I've read a lot about modeling antennas and ground. But what about the
house? Dipole configurations might look like this.

Or this

Or even this

-----------------------------------

(ASCII art looks better in a monospace font)

The house probably makes a lot of difference to gain and pattern, and
also for other antenna types.

Modeling the house as part of ground might make sense, but there will
be lots of differences. Metal roof and sidings would turn the house
into a faraday cage. A wood frame house with no wiring and plumbing
may be almost like air.

Has anybody included buildings in their models, and have they checked
if this made the model more realistic. Any rule of thumb parameters?
