Overview

Completely transformed within the last five years, this beautifully remodeled home in the prestigious Carolands area combines sophisticated elegance with modern luxury on over one-half acre. On a corner lot, with formal and garage driveways, the home is framed from the street with manicured boxwood hedges and entirely oriented to the level rear grounds that have been remarkably transformed for outdoor living. A window-lined gallery wraps around the entire home connecting the public rooms with the bedroom wing, all seamlessly connecting to the rear grounds. Here, a vast stone terrace extends the indoors to the outdoors, connecting to soccer-worthy lawn, and then to a separately fenced, recently added pool and spa alongside an outdoor kitchen and lounge with fireplace. Designed with children in mind – and an absolute recreational delight – the entire setting works equally well for sophisticated entertaining, hosting philanthropic events, and just quiet relaxation in complete privacy.

The residence features 4 bedrooms and 3.5 baths, predominantly on one level plus there is a lower level with recreation room, kitchenette, bedroom, and bath, also working well as separate living quarters for extended family, if needed. Additionally, detached guest quarters, currently customized for remote office work, feature a large desk, built-in cabinetry, integrated Murphy bed for convenience, and custom closets by California Closets. A large adjoining bath offers flexibility for use from the pool as well.

Throughout the property, the entire ambiance exudes designer style – from the gorgeous hardwood floors to the classic crown moldings and window shutters, and everything in between. Lighting selections are ever so modern complemented by recessed lights in most rooms and all-white cabinetry assists with the overall light and bright palette. A central room for formal and everyday living is adjoined by the perfect playroom, music room, office, or additional sitting area. The gourmet eat-in kitchen is positioned between the living room and formal dining room, all with the reminder of outdoor living extending just beyond. At the end of the main-level bedroom wing is the primary suite conveniently located next to two additional bedrooms that share a bath. Just turn the key and move right into this exceptional home – with all its flexibility for a variety of lifestyle needs, superior designer style, and convenient location to top-rated public and private schools.

Hillsborough

Carolands

2023 was a mixed bag for Carolands, which remained Hillsborough’s second-most popular neighborhood in 2023, but on the strength of only 13 sales, four fewer than in 2022 and less than half of 2021’s 29. But there is plenty of good news coming out of the Carolands market. Average sale price was up 8% — with the help of a pair of sales totaling $20 million between them — and the average DOM was down by half, to 30. Average price per square foot was down slightly, as was sale-to-list price ratio. In context, Carolands’ 2023 performance is more positive than negative, a reminder that expectations have changed since the overheated COVID market

Equally known for its pleasant, rolling streets as well as multi-million dollar estates, Hillsborough represents the pinnacle of exclusive yet laid back peninsula homes. With close proximity to all major roads, yet still secluded and private enough for the most discriminating homeowner, Hillsborough’s large but subtle homes and roads-without-sidewalks “woodsy” feel apppeal to many. And, it’s also one of the best and most picturesque towns on the peninsula for a Saturday jog!

The public school system in Hillsborough is among California’s finest, with an excellent faculty to student ratio and a successful technology program. Hillsborough’s Crocker Middle School is well known in the area for its excellent preparation of its students for high school and beyond. And, there are also three excellent private schools in Hillsborough: the Bridge School, which serves students with physical and speech impairments, the Nueva School, a noted elementary school, and Crystal Springs Uplands School, a well established and respected elementary through high school.

As of the year 2000, Hillsborough was the highest income place in the United States for cities of a population of 10,000 or more. The town is six square miles, of which 238 acres are open space and cannot be developed. It’s name comes from the hometown of William Davis Merry Howard in New Hampshire, who visited the peninsula in 1864 as a 16 year old and convinced his shipping magnate father to buy Rancho San Mateo (including what is today the city of San Mateo).

As Hillsborough is all single family homes, the town contributes a portion of the budget to the Burlingame and San Mateo libraries, and shares a fire department with Burlingame, called Central County Fire.

Special Yearly Event: The Concours d’Elegance, benefiting the Hillsborough Schools Foundation, held each August on the golf course started in 1956 by Hillsborough mothers.

Hillsborough is a town of rare affluence, number five on Bloomberg Businessweek’s 2009 list of “Wealthiest Towns in America.” It’s a unique place, with no shops, no restaurants, and no commercial entities of any kind within its borders. Its citizens live on half-acre minimum lots, many behind gates and rows of tall trees.
