For decades, the “double wide” was considered the pinnacle of factory-built housing. But as families grow and the demand for open-concept living increases, a new standard has emerged: the triple wide manufactured home.

Offering between 2,000 and 3,600+ square feet of living space, these homes rival the size of traditional “stick-built” mansions for a fraction of the price.² Whether you are looking for a five bedroom mobile home to house a multi-generational family or simply want a luxury estate without the luxury price tag, a triple wide is likely your best option.

What is a Triple Wide Manufactured Home?

As the name implies, a triple wide manufactured home is built in three separate sections (or “modules”) in a factory.³ These sections are transported on three separate trucks and joined together on-site.

• Width: typically 40 to 50 feet wide.
• Length: often 60 to 80 feet long.⁵
• Construction: Built to the federal HUD code (unlike modular homes, which we will discuss later).

Because they are nearly square in dimensions, triple wides look less like traditional trailers and more like site-built ranch homes. Once a garage and porch are added, it is often impossible to tell them apart from a standard house.

Floor Plan Options: The 5 Bedroom Modular Home

One of the biggest advantages of a triple wide mobile home is the sheer flexibility of the floor plan. Because the home is so wide, architects can include features that simply don’t fit in single or double wides.

The “Multi-Gen” Layout

Many buyers search specifically for triple wide mobile homes for sale because they need space for aging parents or adult children. The most popular configuration is the “Parent/Child” split:

• West Wing: Master Suite (Bedroom 1) with a massive luxury bath and walk-in closet.
• Center: A 600+ sq ft “Great Room” combining kitchen, dining, and living areas.
• East Wing: Two to three standard bedrooms plus a second “Junior Master Suite” (Bedroom 5) with its own private bathroom.

If you are looking for 5 bedroom modular homes, a triple wide layout is often the most cost-effective way to get that bedroom count without building a second story.

Triple Wide Mobile Homes for Sale: Pricing & Costs (2025 Estimates)

While they are cheaper than site-built homes, triple wides are the premium tier of manufactured housing.

Cost Factor	Estimated Price	Notes
Base Home Price	$200,000 – $280,000	Price for the unit only (varies by luxury finishes).
Transport & Set	$15,000 – $25,000	Requires 3 trucks and a crane/large crew to join.
Foundation	$15,000 – $40,000	Requires a massive footprint (see below).
Total Project	$250,000 – $350,000+	Still significantly less than a 3,000 sq ft stick-built home.

Compare this to building a traditional home: A 3,000 sq ft site-built house at $150/sq ft would cost $450,000 just to build. The triple wide offers massive savings.

Critical Considerations: Foundation & Site Prep

You cannot just park a triple wide on the grass. Because there are three sections, there are two marriage lines (the seams where the sections join).

• Foundation Support: The foundation must support the weight of two heavy seams. This usually requires a “Runner Foundation” or a full concrete slab. Standard foundation piers may be used, but you will need significantly more of them than a double wide to prevent the floor from un-leveling and cracking the drywall at the seams.
• Land Width: You need a wide lot. A 50-foot wide home requires a lot frontage of at least 70-80 feet to meet most local setback restrictions.

Triple Wide vs. Modular: What’s the Difference?

When shopping, you will hear the terms “Manufactured” and “Modular” used interchangeably, but they are legally different.

• Triple Wide Manufactured: Built to the HUD Code. It has a permanent steel chassis underneath (even if hidden). It is often financed with a Chattel Loan (if on leased land) or an FHA Title II loan (if on your own land).
• Modular Home: Built to Local/State Building Codes (same as a stick-built house). It has no steel chassis and is lifted by crane onto a permanent foundation. It qualifies for standard mortgages.

If you are searching for triple wide mobile homes but want a basement, you are likely looking for a modular unit, as standard HUD manufactured homes are rarely placed on basements.

Conclusion: Is Bigger Better?

A triple wide manufactured home is the ultimate bridge between affordability and luxury estate living. It offers the square footage of a “McMansion” for the price of a starter home.

However, the logistics of buying one are more complex than a standard single-wide. You need wider land, a stronger foundation, and a larger budget for transport. But for the family that needs 5 bedrooms and a chef’s kitchen, the effort is well worth it.
