3,306 Sq Ft Luxury Farmhouse Plan with Bonus Room and First-Floor Master Suite

Farmhouse LG178 is a sprawling residence defined by a 97-foot, 2-inch width, requiring an expansive lot to accommodate its 3,606 square feet of heated living area. This farmhouse-style design utilizes an 8:12 roof pitch with 9:12 and 12:12 secondary accents, creating a high-profile exterior silhouette that reaches a maximum building height of 27 feet, 4 inches. The structure incorporates 956 square feet of porch space, split between a 243 square foot covered front porch and a 713 square foot rear porch, establishing significant outdoor transition zones.

The interior architecture centers on a 10-foot ceiling height throughout the main level, providing a consistent sense of volume across the open-concept core. The layout features a large keeping room and family room that share a primary fireplace, directly adjacent to an island-equipped kitchen. This culinary space is supported by a walk-in pantry and a butler’s pantry, which facilitates efficient movement into the formal dining area. The floor plan utilizes a split-bedroom configuration, ensuring the primary suite remains isolated from the secondary bedroom wings to increase acoustic and visual privacy.

A 624 square foot bonus room provides additional vertical square footage, offering a flexible space for a media center, hobby area, or guest suite above the garage. The primary suite is engineered for convenience, featuring direct access from the bedroom closet to the laundry room, effectively streamlining household chores. The total 4-bedroom, 4-full-bath, and 1-half-bath layout is optimized for high-capacity living while maintaining clear separation between public social zones and private quarters.

Construction specifications include a 3-car garage occupying 624 square feet, which integrates into the 72-foot, 6-inch depth of the footprint. The inclusion of a dedicated mudroom and utility area further enhances the home's practical utility. Every element of the floor plan is calculated to manage traffic flow, from the direct kitchen-to-dining connectivity to the strategically located bathrooms that serve the secondary bedroom suites.

Key Features: 4 bedrooms, 4 full bathrooms, 1 half-bath, 3,606 sq ft heated living area, 624 sq ft bonus room, 3-car garage, split-bedroom layout, first-floor master suite, laundry-to-closet access, butler’s pantry, vaulted ceiling volume, walk-in pantry, mudroom.

JoAnne and the entire staff was extremely helpful and patient with us while we decided between 2 homes. This home has outstanding curb appeal and a great layout perfect for us. I work from home so having the home office off the foyer is fantastic. I converted the wet bar into a storage closet for my office. We also extended the laundry room into the porch and created a multipurpose laundry/mud room. I would buy from archival designs again and again.

It took almost a year to pick a plan. Since my husband and I retired a few years ago we wanted this last house had to have everything we wanted and needed. The kitchen is my favorite part of the house. I can see what’s happening in my neighborhood through my kitchen window and watch my husband garden in the back yard. Our children think we made a smart decision when we picked this house for our senior years.

We’ve had an amazing experience with our new home and are excited to be moved in. The customer service we received during our modifications was exceptional. We are loving the open layout of the kitchen and family room. It feels spacious and I’m already planning on hosting holiday dinners at home. We recommend Archival Designs to anyone interested in building the home they’ve always wanted!

We absolutely adore the Kildare Place house plan. Made some modifications to make this home ours! Our house is the talk of the neighborhood. We host big parties every holiday and still get compliments from our friends and family. We searched for months and looked through hundreds of floor plans and this one had almost everything we wanted, and with the help of the great staff at Archival Designs we got exactly what we wanted!

FAQ

Can I modify this 3,306 Sq Ft Luxury Farmhouse Plan with Bonus Room and First-Floor Master Suite now or later?

Absolutely. We offer in-house modification services to adjust layouts, room sizes, or expand garages before purchase. If you prefer to make adjustments during the construction phase, purchasing the CAD file package allows your local builder or architect to make on-site changes. Simply click 'Request a Modification' for a free quote.

How much will it cost to build this 3,306 Sq Ft Luxury Farmhouse Plan with Bonus Room and First-Floor Master Suite and why aren't exact costs shown? 

Construction costs vary significantly ($150–$300+ per sq. ft.) based on your location, material choices, and local labor rates. Because site preparation and regional codes differ, it is hard to provide a universal cost always.

Will this 3,306 Sq Ft Luxury Farmhouse Plan with Bonus Room and First-Floor Master Suite fit my lot, and can I add a basement or flip the layout?

You can check the 'Modifications' tab for width and depth requirements. To fit your site's orientation, most plans are available in a 'Right Reading Reverse' (mirrored) format. We also offer slab, crawlspace, and basement foundation adjustments for every design.

Do your plans meet building codes in my area and do I need a professional stamp?

Our plans meet or exceed national IRC (International Residential Code) standards. However, due to varying local requirements regarding seismic, wind (hurricane), or snow loads, house plans do not come with a professional architect’s or engineer’s seal. Most municipalities require a review and stamp by a local licensed professional to obtain a building permit.

Are plumbing, HVAC, and mechanical drawings included?

We provide the architectural and schematic electrical framework, but HVAC and plumbing layouts are not included. Because local codes and climate-specific systems vary significantly across the country, these are best finalized by your local subcontractors to ensure your home’s systems are optimized for your specific site and energy requirements.

Why should I choose Archival Designs and are the plans guaranteed?

With over 40 years of experience, Archival Designs provides high-quality, builder-ready designs that balance aesthetic elegance with structural integrity. We offer a Best Price Guarantee, a 10% discount for military and first responders, as well as builder discounts for life. And loyalty perks for pro builders. All plans are designed to comply with the IRC codes at the time of their creation. Learn more about our Best Price Guarantee.
