For several decades, the American housing market was dominated by what many came to call the “McMansion.” These homes were large, highly compartmentalized, and often filled with formal rooms that looked impressive on paper but were rarely used in everyday life.

Home design trends come and go—but a well-designed house plan should feel intentional and livable for decades, not just a few years. At Peer House Design, we believe the best homes balance current appeal with long-term value. Whether you’re building now or planning for the future, understanding what dates a house—and what truly ages well—can help you choose a smarter plan from the start.

Designing or choosing a house plan is exciting—but it’s also where some of the most expensive regrets begin.

After years of working with homeowners, builders, and developers, we’ve seen a clear pattern: most regrets don’t come from aesthetics. They come from how a home actually functions once real life moves in.

The good news? Nearly all of these regrets are avoidable—if you know what to look for before you build.

Below are the most common floor plan mistakes we see, and how to make smarter, build-ready decisions from the start.

Square footage matters—but not in the way most people think. Bigger doesn’t automatically mean more expensive, and smaller doesn’t always mean affordable. Understanding what square footage actually represents can help you choose a plan that fits your budget and your lifestyle.

Farmhouse-style homes continue to be one of the most requested architectural styles in residential design—but not all farmhouses are created equal. Today’s buyers often find themselves choosing between a modern farmhouse and a traditional farmhouse, two styles that share roots but differ in important ways.

If you’ve ever purchased a house plan and been told, “Your builder will figure it out,” you already know the frustration that comes from plans that aren’t truly build-ready.

At Peer House Design, we use the term build-ready intentionally. A build-ready plan isn’t just attractive—it’s coordinated, clear, and practical enough that a builder can price it accurately and break ground with confidence.

Here’s what build-ready should mean—and what you should expect before construction begins.

Buying land feels like the first step toward your dream home—but in many cases, it’s smarter to choose your house plan first. At Peer House Design, we’ve seen countless clients fall in love with a piece of land only to discover later that their ideal home doesn’t fit the site, the budget, or the regulations.

When people ask, “How much does it cost to build a house?” the honest answer is: it depends—mostly on decisions you control.

At Peer House Design, we work with homeowners and builders every day who are trying to balance design, budget, and long-term value. The biggest misconception? That square footage alone determines cost. In reality, a handful of design and site choices drive construction costs far more than size.

Here’s what truly affects the cost to build—and how to make smarter decisions early.

If you’re looking to add value, generate rental income, or create flexible living space, you’ve likely come across two popular options: duplexes and ADUs (Accessory Dwelling Units). While both can be excellent investments, they serve different goals, budgets, and property types.

Sloped lots often get overlooked by buyers who assume they’re “too complicated” or “too expensive” to build on. In reality, the right house plan can turn a slope into one of your home’s greatest assets—unlocking better views, more light, and flexible living space.

At Peer House Design, we regularly design plans specifically intended to work with the land, not against it. Here’s how to choose the best house plan for a sloped lot—and why these sites can offer incredible value.

For decades, residential development in the U.S. has largely followed a binary model: single-family homes on one end, large apartment complexes on the other. But communities, developers, and homebuyers alike are realizing there’s a critical gap between the two. That gap is where missing-middle housing lives—and it’s quickly becoming one of the most important solutions to today’s housing challenges.

Investing in residential real estate continues to be one of the most reliable paths to long-term wealth—and well-designed duplexes are at the top of the list.
