1. IronRidge

1401 Viejo Ridge Drive, Lake Forest, 949-316-5576; liveironridge.com

IronRidge is emerging in the foothills near Whiting Ranch Wilderness Park in Lake Forest’s Portola Hills area.

Six neighborhoods make up IronRidge: the two-story, single-family home communities of Sagebluff, Brookhaven and Highmark, the two-story, estate homes of Windstone and the three-story, townhome communities of Copperleaf and Silveroak. LandSea Homes is the developer on all the neighborhoods but Highmark, which is being developed by KB Home.

Prices range from the high $500,000s for the two- to three-bedroom townhomes in Silveroak that are 1,300 to 1,693 square feet to the mid-$1.1 millions for the five-bedroom estate homes in Windstone that are 3,272 to 3,814 square feet.

In the Highmark neighborhood, the KB Smart Home System will be offered as a standard feature in all of the homes through the homebuilder’s partnership with Google. Powered by Google Home speakers with Google Assistant, the system will enable homeowners to control features such as a Nest video doorbell, lighting, window shades, cameras and more as well as automate routines to their own preferences. A look at how the system works is available to home shoppers touring the KB Smart Home at Highmark at Ironridge, 2042 Aliso Canyon Drive in Lake Forest.

The private, gated Ironridge community is flanked by nature trails. In the middle is the Ridge, an expansive recreation space featuring such shared amenities as a resort-inspired pool, splash pad, cabanas, picnic pavilion, sports fields and courts, playground and lawn area. Another community park is near the gated entrance, with another sports field, sand volleyball court, play lot, lawn area and large dog park.

2. Rancho Mission Viejo

With the open space known as the Reserve at Rancho Mission Viejo preserved, homebuilding continues on the remaining acreage that is the new community of Rancho Mission Viejo on land that once was part of the gigantic Rancho Santa Margarita Las Flores rancho.

You can see a glimpse of this history at Rancho Mission Viejo’s Cow Camp, the last working ranch in Orange County that still houses vaqueros and their families to take care of the herd.

Now under construction are the villages of Esencia — about a mile up Cow Camp Road from the first developed village, Sendero — and Gavilan.

With 11 all-age neighborhoods in Esencia and seven in Gavilan for those ages 55 and over, homes are available at a variety of price points, sizes and styles. For example, in the Topaz community of Esencia, the Topaz neighborhood offers three- to six-bedroom homes with 3,128 to 4,587 square feet in the $1.5 million range for move-up buyers seeking a lot of space. For first-time buyers and young couples, there are the two-story attached residences of Azure, which are one to three bedrooms, 707 to 1,519 square feet and range from $400,000 to $600,000.

A mid-level home in the village of Gavilan, such as those in the Arista neighborhood, are 1,416 to 1,876 square feet, with two bedrooms over one or two stories and a price of $659,990 to $734,990. Gavilan residents also have access to exclusive amenities such as their own lap pool, boccie ball courts and their own clubhouse called the Getaway.

All residents have access to such amenities as community pools and clubhouses, fitness facilities, parks, playgrounds and nature trails. The long-awaited Esencia school opened to about 400 students from kindergarten through fifth grade last school year, with sixth grade launching this year and then seventh and eighth grades the next two years.

3. Eastwood Village, Irvine

Encore and Jeffrey Road, Irvine, 844-263-6985; villagesofirvine.com

The newest Irvine village of Eastwood is made up of six neighborhoods — Marin, Calistoga, Delano, Avila Beverly and Morro — off Jeffrey Road between Irvine Boulevard and Portola Parkway. It’s an eclectic blend as each neighborhood has its own builder, five in all (Brookfield Residential is building two, Delano and Beverly).

The townhomes in Delano (starting at the mid-$900,000s) are at or nearly at selling out. Single-family homes in Marin (starting at about $1 million), Avila (starting in the low $1 millions), and Calistoga and Beverly (both starting in the mid-$1 millions) are now selling. Single-family homes in Morro, which also will start in the mid-$1 millions, have yet to go on the market.

Grand Trellis Park stretches through much of the village, and there are other outdoor spaces that include sports fields and courts, picnic areas, a Junior Olympic pool and other shared amenities. These are connected by pathways that then connect to the Hicks Canyon Trail as well as a pedestrian underpass to access the Jeffrey Open Space Trail.

Brookfield Residential’s townhomes in the Delano community became the first in the U.S. to offer Apple’s smart-home technology built-in when they went on the market two years ago. Residents can control devices such as their front door locks, lights and thermostats using Apple’s Home app on their iPhone, iPad or Apple Watch.
