Spacious Duplex with Modern Amenities and Covered Porches

Henry is a two-story duplex design encompassing 2,757 sq ft of total heated living area, configured to maximize rental yield or multi-generational utility. Measuring 61 ft 2 in in width and 46 ft 6 in in depth, the structure occupies a footprint that fits standard suburban lots while providing separate living quarters. The design incorporates 4 full bathrooms and 2 half bathrooms, ensuring private facilities for residents in both units.

The first floor provides 1,871 sq ft of space, anchored by an open-concept core that integrates the kitchen, dining, and living zones. A central kitchen island serves as the primary workspace, supplemented by a dedicated walk-in pantry for dry storage. The layout maintains 9-foot ceilings on the main level to increase interior volume and light penetration, while the 8-foot ceilings on the second floor create a more intimate scale for the 885 sq ft upper level.

Structural integrity is achieved through 2x4 wall framing and a 9:12 roof pitch, resulting in a maximum building height of 25 ft 9 in. The home is constructed on a crawl space foundation, which allows for site elevation and utility access. Exterior elements include a 60 sq ft covered front porch and a total of 390 sq ft of porch area, offering transition zones between the interior living spaces and the surrounding site.

Practical amenities include integrated fireplaces in the living areas and significant walk-in closet space for each bedroom. The duplex configuration utilizes a split-bedroom layout to enhance acoustic privacy between sleeping quarters and the shared living zones. This architectural model provides a balanced approach to multifamily housing with durable construction methods and efficient interior circulation.

Key Features: 2,757 sq ft total living area, duplex configuration, 9-foot first-floor ceilings, 8-foot second-floor ceilings, 9:12 roof pitch, crawl space foundation, kitchen island, walk-in pantry, covered front porch, multi-generational living, split-bedroom layout.

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 Spacious Duplex with Modern Amenities and Covered Porches 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 Spacious Duplex with Modern Amenities and Covered Porches 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 Spacious Duplex with Modern Amenities and Covered Porches 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.
