Carriage House Plans, Garage Apartment Plans & ADU Designs

Carriage houses, or coach houses, were initially built to keep horse-drawn carriages safe. Nowadays, they’ve transformed into separate garages with living quarters on top. They give their homeowners extra room to live in, with layouts that can be customized quickly. Common features included in carriage house plans are garage space, private living quarters, and additional storage, with some plans offering amenities like bathrooms or kitchenettes as part of the base design. Whether you want an oversized garage or space for just one car, these homes are an excellent and valuable addition to any property.

Today, many people are fascinated by old-style carriage houses but those kinds of houses are hard to find. So, many homebuyers who dream of living in such houses, decide to build their own. Many new carriage house plans are inspired by traditional designs or traditional architectural styles, and might resemble the old ones but are meant for just one family. Some even use old designs to build garages with extra storage or cool hangout spots.

History and Benefits

Originally constructed as outbuildings on large estates, carriage houses were designed to store horse-drawn carriages and provide living quarters for staff. Over the years, these structures have evolved to serve a variety of modern purposes, offering homeowners valuable benefits such as additional living space, secure storage, and increased property value. Today’s carriage house plans often include garage apartments, making them a popular choice for those looking to add a guest house, in-law suite, or rental property to their land.

With a range of plans to choose from, you can easily find a carriage house that fits your needs, enhances security, and adds a touch of classic charm to your property.

Features of Carriage Home Plans

Interior features: 

Carriage Houses typically have high ceilings, reaching 20 feet or even more on the first floor. They are usually built with two floors, and some even have a room upstairs where typically the coachmen would stay. Windows are designed out front which means this style of house gets limited natural light. 

Exterior Characteristics 

Carriage houses possess different roof styles, such as gable or gambrel roof layouts and flat or sloping roofs. They also have big garage-style doors with limited side windows. The exterior of the house is made of materials such as brick, vinyl, or wood. 

Size of the Carriage House 

Carriage houses come in various sizes, depending on where the building is located. City Coach houses were smaller and simpler in design, large enough to store horse-drawn carriages but not enough for the coachmen. 

However, rural cart sheds were big and well-made. They sat on large land areas, fitting multiple carriages and their gear. Wealthy homeowners usually added stables for their horses and enough living space for drivers and all staff. 

Other features: 

• Larger Doors 

• Open Floor Plans

• Unique Architectural detail

• Living spaces that are entirely functional

What Makes a Carriage House Plan Unique?

A carriage house plan blends vehicle storage and livable space into one efficient structure. Traditionally inspired by historic carriage barns, today’s versions combine a garage on the first floor with a compact residence above — often including a bedroom, bathroom, kitchenette, and open living area.

Key Characteristics

• Garage on the main level (1–3 cars)

• Living quarters above or beside the garage

• Ideal for narrow or secondary lots

• Flexible layout for guests, renters, or home offices

• Cost-effective and space-efficient construction

• Can function as an ADU, studio, or multi-purpose building

Why Carriage Houses Are Popular Today

Modern homeowners choose carriage house plans because they offer:

• Affordable construction compared to full-size homes

• Rental income potential (Airbnb, long-term rentals)

• Privacy for guests or extended family

• A separate studio, office, or hobby space

• Attractive solution for properties needing a small footprint

Carriage house plans allow you to enjoy the comfort of a compact home with the practicality of integrated garage space — making them one of the most versatile small home designs available.
