Qualities of a Custom Designed Home

McCullough Design Development (MDD) is the single source for an integrated Custom Estate Design-Build experience in San Diego County. While implementing all services in-house, from concept planning through construction, they efficiently allow for budgets and schedules to be met with ease.

Families are spending more time at home, providing the opportunity for many to re-evaluate what “home” encompasses, delving into priorities and aspirations when it comes to living authentically. MDD excels at taking those ideas and lifestyles and translating them into beautiful homes that evoke an emotional connection while remaining within budget. The epitome of MDD’s philosophy of a well-crafted home is built on thoughtfully considering how design can meet function and longevity.

Its latest telling in luxe architecture, The Novel Farmhouse, exemplifies this streamlined sensibility. Nestled on a pinnacle point in Del Mar Mesa overlooking a serene coastal valley, ideal living is created. At a time when homes are repurposed as a beloved restaurant, fitness center, place of employment, and classroom, designated areas have become vital in maintaining a harmonious living atmosphere. Versatility abounds in this 4 bedroom, 4.5 bathroom, and 4-car garage residence featuring a workout studio, home office, TV cavern, private spa patio, and 2-room flex space pre-planned for a future guest house. A true estate displaying energy efficiency with a Tesla Powerwall, photovoltaic solar, UV air purification filter, and drip irrigation system.

Designed to coalesce as one, the indoor-outdoor living dynamic blends nature’s palate with hand-picked, custom selections of crisp ivories, sandy beiges, and solstice blues, evolving this residence into a place of peaceful recreation and relaxation. The calm expansiveness of the great room maximizes both natural light and unending views juxtaposed with the glass-encased wine wall completing the space with opulent sophistication. Adorned in light wood cabinets and black modernist appliances the entertainment kitchen affixes a full-service prep-kitchen and dry pantry fitting for all culinary goals.

The great room, primary bedroom, and workout studio occupy a direct connection to the outside through panoramic sliding glass doors. Once opened, your senses become immersed in the delightful medley of idyllic coastal breezes, boundless scenery, and harmony of nature quietly growing around you under the covered veranda, creating every opportunity for indulgence of SoCal living.

Barbecue favorite meals in the al fresco kitchen then revel in delicious food around the veranda island while friends and family gather to watch movies by the fireplace. In ultimate connection with the landscape beyond, dive, float, or wade in the property’s impressive infinity pool completed by an illuminating fire bowl, beach entry, and Baja shelf.

As the first and last place one finds themselves each day, the primary retreat presents as an exclusive experience. Room to bask in a quiet morning coffee or evening glass of wine as the backyard’s cinematic views beckon. Displaying high-end cabinetry and a hidden secret/safe area, the refined dressing room provides beautiful closet storage. A large soaking tub peers out to the private spa patio affording restful solitude and the melody of a waterfall fountain.

Lead architect, Monty McCullough, has developed an affinity for learning new techniques, discovering that one individual creation always leads to the next. MDD wholeheartedly believes in the mantra of quality over quantity, and the timeless aspects of architecture that will endure for generations to come. Today and everyday “home” should be synonymous with a personal oasis; a place where you not only live but become alive.

McCullough Design Development (MDD Homes) announces its record-breaking sales! Two luxury estate residences have officially SOLD this week and one custom lot is pending after the successful Grand Opening of MDD’s newest chapter in design, which debuted at the beginning of February in the Rancho Valencia Resort community. Hidden within the lush surroundings of Ranch Santa Fe and characterized by a storyteller’s twist on California-Spanish architecture, this home pairs a smooth stone and stucco exterior with modern contemporary features and vibrant landscaping.

Also sold on the same day was MDD’s Modern Farmhouse in Artesian Hills—a perfect contemporary interpretation of the classic homestead, with all the latest features and finishes exuding a juxtaposition of warm wood elements and mixed metals throughout the space portraying the perfect transitional balance. Completed by an attached Accessory Dwelling Unit (A.D.U.) with its own address, parking, laundry, and full-service kitchen.

MDD’s Modern Farmhouse in Artesian Hills – SOLD

Curiosity and innovation fuels MDD’s living spaces to be both beautiful and functional. The company’s intentional choices make these areas interesting and inspiring places to live, truly speaking to the soul about authenticity and individuality, yet also taking care to address practical connectivity needs.

While MDD is currently sold out of ready-to-move-in homes, they will be rolling out more custom homes in early 2021. “We’ve got exciting things coming! We’ve committed more closely than ever on designing residential amenities and spaces that encourage interaction, build memories and are multipurpose, so they effortlessly adapt today and far into the future,” states Monty McCullough, president and owner of MDD Homes.

If you’ve missed out on their finished homes, don’t fret, they still have a few pieces of estate property ready to build on for custom clients in West Carmel Valley and Encinitas. “As Much as we love building our own homes, we love working with custom clients to build their vision!” says Lori McCullough, Co-Owner.  The possibilities with MDD are endless and imaginative.  For more information on their Custom Home Program call Lori McCullough at (858) 431-9622 or email or visit


MDD’s Grand Opening Success!

News & Events

Grand Opening Success!

A Modern Farmhouse style showcase model home in Artesian Hills and a brand-new coastal estate in Carlsbad made their debut last month from San Diego Builder, MDD Homes. The result? A combination of the two open houses garnered an 800-person turnout in one weekend. The showcase model home, however, was the main event, complete with an in-house culinary artist preparing light hor d’oeurves and bite-sized desserts for people to enjoy as they strolled through the sprawling estate.

From the moment you enter the 4,675 sqft. dwelling through the 10ft tall gravity pivot door you are struck with an expanding great room that seamlessly bridges the gap between indoors and outdoors, allowing a vast, panoramic view of southern California’s hillside terrain from the grand veranda. A common theme noted over the weekend was about this unique characteristic, “I love the openness when you first walk in.” Others described how it applied to the family unit and recreation, “truly a house designed for spending time together and entertaining guests.”

The excitement and enthusiasm from visitors pulsated throughout the walls of the home, as the whispers of what a possible future life on the 2.5-acre estate would look like carried through each room. The highest of compliments were conferred upon the MDD Interior Design Team, as their use of sophisticated finishes, contrasting colors, and luxurious textures boasted a visually appealing aesthetic. A favorite spot in the whole of the house was the spa-like retreat master bathroom. Outlined by its flat panel glass enclosure, black granite backdrop, stainless steel tub, and waterfall showerhead.

The attached Accessory Dwelling Unit (A.D.U.) with its own address, parking, laundry, and full-service kitchen, impressed many with its practicality and usefulness in today’s housing crisis. Another point of interest for visitors was the prep-kitchen or butler’s pantry, expertly demonstrated by MDD’s on-site cuisinier. The immaculate kitchen sparkled, but just behind it all the hard work that went into making the event preparations could be seen. A perfect test to show the practicality of having such a feature.

A special treat for MDD was when the many familiar faces it has gotten to know over the years through custom build projects, stopped in to tour the home and show their support. In talking with Monty McCullough, owner of MDD Homes, one previous client stated, “This is what we have been waiting for! We are ready to build with you again.” Another said, “we have been following your homes for years, but this is by far my favorite.” Mentions like this stand as a testament to MDD’s quality and uniqueness of design and their attention to the details, separating them from other builders in the area.


MDD Unveil Plans for 2019

MDD Unveils Plans for 2019

San Diego’s economy over the past year is one of the strongest in California and continued income growth is expected, making investing in a real estate in San Diego—especially in homes— a beneficial decision. But home ownership gives so much more than gaining equity and tax deductions– it provides the freedom to live as you want, build memories and give an endurable legacy to the next generation.  “A house means something different to each of us, but when you add in all the special touches of family, and cherished memories that’s when a house becomes a home and it is an investment worth making,” Says Monty McCullough, Owner of MDD Homes.

McCullough Design, one of San Diego’s premier Custom estate builders, recognizes that the demand for a place to call home is alive and well– whether clients are looking to build brand new, buy as a rental, or add to their existing home they aim to deliver in 2019. 

The 2019 Local Line Up:


MDD’s flagship Model Home will be opening in the Spring.  Expect a fresh face for this showcase home which shows the latest amalgamation of Modern Farmhouse with the sensitivity of yester year and all the modern comforts and styles.  It will yield spaces equally fit for a glamourous cocktail party or a quiet winter evening by the fire.


The Company will also finish their coastal mini-estate in La Costa/Carlsbad in the Spring.  A lot of heart is packed into this 3,211 sq. ft. 4 Bed, 3.5 Bath gem.  Featuring flexibility with room to grow and adapt as family dynamics change, the floorplan offers more than meets the eye at first glance.  With a fully accessible and private 2 room guest area there is plenty of room for multigenerational living, income generating rental, a private office, or just the occasional house guest. The prime location has easy access to both freeway and recreational activities such as Encinitas Ranch Golf Course and Batiquitos Lagoon. 


McCullough will also break ground on their home in Bridlewood Estates in Poway and finish construction in the Fall.  A beautiful and simple 3745 sq. ft. plan including 4 BD/3.5 BA has all of the high-end amenities and unique features you would expect to see in a MDD home.  The options to add an attached 888 sq. ft guest suite, patio/veranda and extra 2 car garage gives the homeowner the choice to adapt the home to their specific needs.

And if a custom home is more your style, MDD also has finished lots available, ready to build on just waiting for your vision and creativity.



Located in the Del Mar Mesa community of West Rim in Carmel Valley, hidden against a quiet canyon preserve, McCullough has 2 lots that have the potential for large estate homes with golf course views. MDD created predesigned single-story floor plans maximizing the best views for potential homeowners to start the custom home design process. Each floorplan capitalizes on the regulations for an Additional Dwelling Unit (ADU)—a fully equipped and autonomous guest house with cooking facilities—perfect for meeting the needs of today’s families.


Deep inside the Rancho Santa Fe neighborhood and included in the Rancho Valencia Resort & Spa lies a secluded elevated lot that is perfect for a peaceful getaway with panoramic mountain views and ocean breezes. Pre-designed plans are available for a 5,402 sq. ft. single level plan that has a modern Spanish flare complete with 4 BD./4.5 BA, courtyard and bonus/rec room pre-plumbed for a full serviced guest suite/ADU.

Still just love your current neighborhood and can’t bring yourself to move? MDD has a plan for that too.  Incorporating new elements into an existing dwelling and restoring life back into the framework of a structure is their passion.  Whether it’s gutting the interior, a room addition, or a resort backyard, they combine their talents of design/build to recreate spaces that are functional and beautiful.  


Framing: A Modern Farmhouse

News & Events

The Modern Farmhouse Style

As stated in an earlier post, MDD Homes is working on an exciting new project: a modern farmhouse style model home coming next year (see rendering below)! The construction process is going well and the house (so far) looks fantastic!

Now, “modern farmhouse” sounds slightly ironic and perhaps a bit like an oxymoron, such as: small crowd, living dead, or random order. However, this style is currently the top exterior design trend sweeping our country. It calls upon traditional designs mingled with modern textures; a family-friendly, classic feel with a contemporary twist! Defining the modern farmhouse look includes polished horizontal and vertical wood sidings, a full or partial metal roof, and the tasteful use of contrasting colors. Porches, columns, and stone accents all unify to develop this stand alone style!


Right now it may just look like a tangle of wood, nails, and sawdust, but what you see in the photos below is the most vital step of the whole process. We’ve got all three “f’s” going on here: Footings, Foundation, and Framing.



Before construction can even begin, however, a thorough consideration of the design process must take place. This includes making sure every facet of the home is rightly placed so you can get the most out of your square footage and views. This open layout where the kitchen, family room, and dining room all combine to form one great room making you feel right at home, encouraging togetherness, and enjoying relaxed meals. Sliding doors leading out to a outdoor veranda/porch with a fireplace create the perfect spot for gathering, unwinding, and appreciating nature.

The Del Mar Mesa: Community and Opportunity

In 2018, Del Mar Mesa ranked as the no.1 best place to live for families in California based on criteria such as: cost of living, jobs, schools, diversity, activities, and safety. It is one of San Diego county’s most sought after localities for a reason.

A Southern Californian stretch defined by the grandeur of over 900 acres of preserved open space habitat particular to rolling hills, coastal canyons, and Eucalyptus groves. It is also home to the Grand Fairmont Del Mar Hotel and Golf Course, voted by multiple travel magazines in 2017 as one of the best hotels in the U.S.A. Top rated schools (Sage Canyon Elementary, Carmel Valley Middle, Torrey Pines High) coupled with over 10 miles of hiking, biking, or horseback riding trails make for the ideal community environment.

These two custom lots are full of opportunity for you and your family and perhaps the last chance for anyone to have a home built to suit their every need and want in the Del Mar Mesa area. MDD Homes has designed unique and pre-approved floorplans for each lot:
