Not so small. Or cheap. But it is large:

“Embassy Baghdad” will dwarf new U.S. embassies elsewhere, projects that typically cover 10 acres. The embassy’s 104 acres is six times larger than the United Nations compound in New York, and two-thirds the acreage of Washington’s National Mall.

Now that's what I call "independence!" Sure sounds cozy to me:

The designs aren’t publicly available, but the Senate report makes clear it will be a self-sufficient and “hardened” domain, to function in the midst of Baghdad power outages, water shortages and continuing turmoil.

It will have its own water wells, electricity plant and wastewater-treatment facility, “systems to allow 100 percent independence from city utilities,” says the report, the most authoritative open source on the embassy plans.

Besides two major diplomatic office buildings, homes for the ambassador and his deputy, and the apartment buildings for staff, the compound will offer a swimming pool, gym, commissary, food court and American Club, all housed in a recreation building.

Security, overseen by U.S. Marines, will be extraordinary: setbacks and perimeter no-go areas that will be especially deep, structures reinforced to 2.5-times the standard, and five high-security entrances, plus an emergency entrance-exit, the Senate report says.

One wonders about the rooftop helopad situation, although the article fails to discuss that.
