Indoor-Outdoor Living in Every Model

Toll Brothers’ Sterling Grove Community bridges design and nature

In a park-like setting surrounding a Nicklaus Design 18-hole golf course in Surprise, Arizona, Toll Brothers has created an oasis of indoor-outdoor living.

The company calls its new Sterling Grove community “a remarkable collaboration between design and nature.” Built around moving walls of glass that flood homes with fresh air and natural daylight – and blur the boundaries between the interior and the exterior – the models at Sterling Grove have impressed homebuyers touring the eight new home collections.

“The reactions to Sterling Grove have been fantastic. We really embrace the indoor-outdoor living here,” says Dan Rhea, senior project manager for Toll Brothers at Sterling Grove.

Indoor-outdoor spaces in the homes at Sterling Grove are designed for al fresco dining, entertaining, and gaming.

Set on 780 acres, the community is centered around a tree-lined courtyard with four cornerstone parks, streams and ponds, desert gardens, and fragrant citrus groves. The community features 25 home designs ranging from 1,500 to over 4,000 square feet, and all merge landscape and architecture through the use of massive moving glass walls.

“We bring indoor-outdoor living into every model we create, regardless of the size,” Rhea says, “and with that, the key component is the multi-slide door.”

Model homes at Sterling Grove showcase the Series 600 Multi-Slide Door and the Series 3700 Vinyl Multi-Slide Door. Rhea has his favorite things about each product.

“For the Series 600 Multi-Slide Door, it’s definitely the low threshold option you can get,” he says. “It is such a great way to introduce indoor-outdoor living with a seamless transition.”

“My favorite thing about the Series 3700 Vinyl Multi-Slide Door is two-fold,” Rhea says. “First of all, it’s competitively priced. And then, it offers high energy efficiency.”

Energy efficiency is important to Toll Brothers, and Western Window Systems’ multi-slide doors helped them achieve their energy efficiency goals through the use of low-E, argon-filled glass and thermally broken aluminum.

“All of our homes here at Sterling Grove are Energy Star rated,” Rhea says. “We integrated Western Window Systems into those plans and have come out with some amazing HERS ratings.”

Multi-slide doors create open spaces and blur the boundaries between the inside and outdoors at Sterling Grove.

A closed 90-degree multi-slide glass door separates the outdoor living space and pool from the indoor living and dining room.

A 90-degree configuration of Series 600 Multi-Slide Doors eliminates a connecting post, creating a seamless transition from the indoors to the outside.

The energy efficiency and ease of operability of Western Window Systems doors makes it an attractive option for homebuyers who want indoor-outdoor living, and a perfect partnership for builders who want solid service.

“Western Window Systems is really a turnkey solution for us. The quality and the service we get from them is absolutely outstanding. The company stands behind their product,” Rhea says. “The service is great, the installation is easy, and people really enjoy the ability to open the doors up and just really enjoy this wonderful Arizona environment.”
