The Lamonette Residence

A Designer's Dream Hampton’s Style Home In Orange County And Los Angeles County Inspired by the elegant Hampton’s Style home that is common in the New England coast, this ground-up custom home build in the Los Angeles area features an attached collector’s garage, daily-drivers garage and workshop. The home seamlessly combines traditional east coast charm with a contemporary floor plan that is popular in Southern California. The home is casual yet sophisticated and feels bright and breezy with plenty of natural daylight and crisp white woodwork. Imagine a home that embodies everything you love about the East Coast, but fined tuned to your West Coast lifestyle. A home where guests feel at ease and the sophisticated luxury design is balanced by laid-back coastal-style touches.
Welcome to The Lamonette Residence.
 Because HartmanBaldwin built this luxury custom home from the ground up for our clients, they were able to come to us with a binder of inspirational images for each room, knowing every space could be a passion project. Our team shared their enthusiasm for the project's success and poured their full talents into its execution. Inspired by the elegant Hampton’s Style homes that are common along the New England coast, this ground-up custom Shingle Style home in the Los Angeles area features an attached collector’s garage, daily-drivers garage and workshop. This home was custom built specifically to match the needs of our clients and the landscape of the lot. Windows, door panels, and stained glass were strategically placed to maximize natural light and views of the property. Fire risks were addressed by crafting the characteristic shingles and trim with fire-resistant materials.
