Below is a list of custom home builders in Florham Park, New Jersey, the builders who can help homeowners build the home of their dreams, no matter the budget. These builders were selected by our editorial team for their strong backgrounds, unique experiences, and the ability to collaborate with homeowners to achieve and exceed client expectations. 


Grant Homes

1 E. Main Street, Mendham, NJ 07945

Grant Homes is a premier builder of the finest luxury custom homes and residential properties in New Jersey. The firm’s founder and owner, Jay Grant, started the company in 1984 after graduating from Tulane University. A second-generation builder himself, Jay has assembled a skilled team of professionals who ensure that the building process is successful and fun for the clients. He holds his skilled craftsmen—many have been with Grant Homes for over 20 years—to the highest quality standards. 

One example of the firm’s work is this Dutch Colonial home in Princeton. In New Jersey, you will find that many homes are built in the Dutch Colonial style, due to settlers from the Netherlands building their homes in the area. Dutch Colonial homes, like this custom home below, typically feature gambrel roofs and chimneys. But this home veers away from the typical brick or stone materials for the exterior, instead employing wooden clapboard siding painted in a clean white. The window groupings are uniform, adding a sense of symmetry to the home. Finally, trimmed hedges and an expansive lawn complete the home’s look, making it a charming, warm place to come home to. 


Geiss Custom Builder

327-1/2 Millburn Avenue, 2nd floor, Millburn, NJ 07041

With over 150 luxury homes and countless remodeling projects comprising its portfolio, Geiss Custom Builder is a premier construction and renovation company offering luxury services to clients across Northern and Central New Jersey. The firm was founded by Cliff Geissler, a Graduate Master Builder, a Certified Graduate Remodeler, and a 2012 and 2013 Awards of Excellence Winner from the Community Builders and Remodelers Association of New Jersey.

One great example of the firm’s work is this custom home in Short Hills. The firm built this home in 2010-2011. It features an elevated exterior of stone and wooden clapboard siding, which makes for a charming and clean façade. Inside, the home features a spacious foyer to welcome guests, an eight-seater dining table, and a modern kitchen complete with island and counter seating. The living room includes trendy sofas with an abundance of throw pillows. Meanwhile, the bedrooms are the perfect respite from the humdrum of the day. 


Jack Finn & Company Building Contractors LLC 

Suite 2, Brassworks on Grove, 105 Grove Street, Montclair, NJ 07042

Jack Finn & Company is a local residential renovation and custom home building company established in 1980 by its namesake, Jack Finn. Jack employs a team of experienced project managers, carpenters, and tradesmen who bring their expertise to the construction site for timely and elegant completion on every job. Since 2006, the company has also completed some commercial renovation projects, including two Leadership in Energy and Environmental Design (LEED) Gold commercial buildings in Montclair.

Pictured below is an example of the firm’s work on a residential project. The project scope of this existing turn-of-the-century residence in Florham Park involved an addition and a renovation. Construction of the addition included the installation of a support kitchen, exercise room, full bathroom, and executive home office. The home’s new three-car garage also included the creation of a gated, heated motor court. The firm also built a pool pavilion with a fireplace. The homeowners wanted to match the exterior finishes of the new addition to the existing residence. One challenge the firm encountered—a challenge met with minimal problems—was to ensure that the graduated slate roof, pecky cypress trim, windows, and French doors were an exact match to the existing façade.


WA Construct

700 Kinderkamack Road, Oradell, NJ 07649

Originally established in Pakistan but in business today in New Jersey, WA Construct, formerly known as MS Warraich Associates, is a construction and renovation firm driven by both customer satisfaction and a passion for the craft. The firm is owned by Hasnain Nasar, an entrepreneur and builder with more than fifteen years of experience in construction and interior designing. Hasnain leads the firm as it offers comprehensive building services to clients, whether clients are looking to build a site from scratch, complete a major renovation, or put in a simple addition. 

One example of the firm’s work is this custom home in Florham Park. The snowy landscape of this custom home does nothing to deter this painted white custom home from standing out. With its wooden clapboard siding and black outlined windows, the home has an imposing presence softened by the peeking stone elevation at the base of the home. Inside, muted wood tones deck the floors of the spacious rooms throughout the house. Beyond the front door, you are immediately met with a foyer/living room with a stone fireplace. To the right of this area are the open concept kitchen and dining room with traditional furnishings. Upstairs, the expansive bedrooms and bathrooms are perfectly secluded from the activity downstairs, allowing the owners undisturbed privacy from the rest of the house.


L.G. Leider Homes

152 Rockwood Road, Florham Park, NJ 07932

Soon after Lenny Leider founded L. G. Leider Homes, his firm grew to become a premier builder in the luxury home market in the Madison and Summit, New Jersey areas. Lenny and his team of professionals at L. G. Leider Homes are known throughout New Jersey for high-end luxury homes that use only the finest workmanship and quality materials—materials that last for generations and make the environment a priority. 

One example of the firm’s work is this home in Chatham Township. Built as a spec home, this 6,000-square-foot house was the winner of the 2016 “Best Single Family Home Over $2,000,000” award from the Metropolitan Builders and Contractors Association. The home features a magnificent and stately exterior thanks to its portico with a roof and brick siding. The muted shades of the roof and exterior also come together to create a warm, inviting appearance. The bay window at the center of the home serves as both a break in the symmetry for the exterior and a lovely nook with a view for the interior. Overall, the home is both charming and grand—a beautiful sight to behold from the street.
