Three Season Room Collection
Three Season Room house plans blend indoor comfort with outdoor living through expansive windowed spaces that can be enjoyed spring through fall. These light-filled rooms typically feature large windows on three sides, vaulted ceilings, and seamless transitions to both interior living areas and outdoor patios or decks. Originally popular in New England as "sunrooms" or "Florida rooms," these versatile spaces have evolved to become sought-after features in homes across North America.
The defining characteristic of Three Season Room designs is a glass-enclosed living area that acts as a buffer between indoor and outdoor spaces. These rooms commonly incorporate energy-efficient windows, sliding glass doors, and screened sections that can be opened to welcome fresh air. While not typically heated or cooled like year-round sunrooms, these spaces often include ceiling fans, removable window panels, and UV-protective glass to maintain comfort across multiple seasons.
Modern Three Season Room floor plans frequently position these spaces off main living areas or kitchens, creating natural entertainment zones that expand the home's usable square footage. Common layouts include open-concept designs where the three season room flows from family gathering spaces, creating sight lines through the home to outdoor views. Many plans feature 12-16 foot depths and lengths of 16-24 feet to accommodate both seating areas and dining spaces.
Today's designs incorporate contemporary amenities like low-maintenance composite decking, remote-controlled window shades, and all-weather furniture options. Popular upgrades include radiant floor heating, motorized screens, and indoor/outdoor fireplaces that extend seasonal use. These adaptable spaces serve as home offices, yoga studios, garden rooms, or casual living areas that connect inhabitants with nature while providing protection from insects and weather.
Particularly well-suited for lots with scenic views or mature landscaping, Three Season Room house plans appeal to homeowners who value indoor-outdoor living without the full expense of a four-season sunroom addition. The abundance of natural light and connection to the outdoors has been shown to improve mood and create inviting spaces for relaxation and entertainment. Whether used as a quiet morning coffee spot or evening gathering space, these rooms add versatility and value while maintaining energy efficiency compared to fully-conditioned additions.

Foundation Types
When de signing our house plans, a default foundation is set for a given plan. If possible, we include options to change the foundation type to better match your construction needs. For instance, if the default foundation is an unfinished basement, you'll have the option to change the foundation type to a walkout foundation, crawlspace, or slab foundation.
Please note: Some of our plans are designed with special foundation needs, such as post and pier for waterfront properties. These plans may not allow an option to choose another foundation type. If you find yourself in need of an alternate foundation and aren't given the choice, please fill out the alteration request on the plan page.
Right Reading Reverse
One of our more popular options is reversing the plan. Ordering the reverse option will not only flip the plan on the sets for you, it will also correct the text to make the plan read correctly while reversed.

All of our plans are offered as digital PDF downloads. If you want to make changes to the plan yourself, there is an add-on option that will give you the CAD files. Our CAD files are exported in AutoCAD format. You must have software capable of opening CAD files to use them. This option is great if you are in the business of home building and need to make slight changes to the plans per lot.
