Architect fees in the Los Angeles areas

Hello all,

i'm looking for an architect for a 2 homes project in the Malibu area.

The plan is to build 2 nice different modern homes on 2 lots side by side.

I know architect fees range in the 10% area, however, given the high budget of such project, around 1.5 millions, i was wondering what is the fair rate and if the fee should include consultants and engineering costs.

Any input would be appreciated

Best
