Its thoughtfully designed floor plan delivers privacy, comfort, and convenience while maintaining the welcoming appeal of traditional residential architecture.

The duplex spans 66 feet in width and 40 feet 8 inches in depth, creating a balanced and attractive exterior presence suitable for a variety of neighborhoods and lot configurations. Finished with a combination of brick veneer and siding, the home achieves a timeless appearance that blends durability with classic curb appeal. A traditional stick-framed roof with an 8:12 roof pitch enhances the home's character, while the overall building height of 19 feet 1 inch maintains an approachable residential scale.

Designed as two separate yet symmetrical residences, Unit A and Unit B each provide approximately 1,035 sq. ft. and 1,036 sq. ft. of heated living space respectively. Both units are arranged entirely on a single level, offering exceptional accessibility and convenience for homeowners, tenants, retirees, or families seeking stair-free living.

Each residence features a welcoming covered front porch measuring 32 sq. ft., creating an inviting entrance and a pleasant outdoor space for relaxation. At the rear, a private 29 sq. ft. stoop provides convenient outdoor access and enhances the functionality of each unit while preserving privacy between households.

The interior design emphasizes efficient use of space through an open-concept floor plan that seamlessly connects the kitchen, dining, and family living areas. This arrangement creates a bright and spacious atmosphere while encouraging interaction and comfortable everyday living. Large windows allow natural light to flow throughout the interior, contributing to a warm and inviting environment.

At the heart of each unit is the keeping or family room, a comfortable gathering space designed for relaxation, entertaining, and daily activities. The open layout ensures easy movement between living areas while maximizing the sense of openness within the home's footprint.

The duplex includes a total of 4 bedrooms, with 2 bedrooms located in each residence. These thoughtfully arranged sleeping quarters provide privacy and flexibility for a variety of living arrangements. Whether accommodating small families, roommates, retirees, or guests, the bedroom layouts support comfortable and efficient living.

One of the standout features of each unit is the private owner's suite. Conveniently located on the first floor, the suite offers a comfortable retreat complete with a private bathroom and a walk-in closet. This arrangement enhances both privacy and functionality while providing the conveniences expected in modern residential design.

The overall duplex includes 4 full bathrooms, with each residence containing 2 full bathrooms. This generous provision of bathroom facilities ensures convenience for occupants and guests while supporting the needs of contemporary households.

Additional practicality is provided through dedicated first-floor laundry facilities within each unit. By placing laundry spaces on the main living level, the design simplifies household tasks and contributes to the overall efficiency of the floor plan.

The home is built on a durable crawl space foundation and utilizes dependable 2x4 wall framing, supporting long-term structural performance and straightforward maintenance. Throughout the residence, 8-foot ceilings create comfortable room proportions and contribute to a welcoming atmosphere.

The single-story configuration enhances accessibility and makes the duplex particularly appealing to retirees, downsizers, and homeowners seeking ease of movement. At the same time, the dual-unit arrangement creates opportunities for rental income, extended-family living, or investment ownership.

Blending traditional architectural charm with modern convenience, this duplex offers a highly adaptable living solution. Its combination of private residences, open-concept interiors, covered porches, and comfortable bedroom suites makes it an excellent choice for homeowners and investors seeking long-term value, flexibility, and enduring appeal.

Review image
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 Classic Traditional Duplex House Plan with 4 Bedrooms, Open Living Areas, and Single-Level Convenience | Holden House Plan 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 Classic Traditional Duplex House Plan with 4 Bedrooms, Open Living Areas, and Single-Level Convenience | Holden House Plan 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 Classic Traditional Duplex House Plan with 4 Bedrooms, Open Living Areas, and Single-Level Convenience | Holden House Plan 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?

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.
