I have two examples of new construction, single family homes in the 3000-4000 s.f. range in Brentwood and North of Wilshire Santa Monica selling well under $850/ s.f.
12314 Gorham Sold $2,150,000 - 4600 s.f. @ $467.39 s.f. - 06/05/2009
1024 23rd Street Sold $2,425,000 - 3500 s.f. @ $692.85 s.f. - 05/22/2009
There may be homes that are selling closer to $850-$1,000 s.f. but it isn't hard to find home selling for less in Brentwood and Santa Monica. Generally speaking the larger the square footage of the home the less per square foot you pay. There are exceptions, however.
