Custom Sunrooms That Connect Your Home to the Outdoors – Year Around

A sunroom is one of the highest-value additions you can make to a home in Virginia, Maryland, or DC. It expands your living space, floods your home with natural light, and gives you a comfortable connection to the outdoors in every season — without the cost or disruption of a full home addition.

At City Deck, we bring decades of full-service construction experience to every sunroom we build. That means proper structural foundations, seamless integration with your home’s existing architecture, and the expertise to handle everything from framing to finishing — including HVAC, electrical, and custom window installation.

FREQUENTLY ASKED QUESTIONS

Sunroom FAQs

01. How much does a sunroom cost in Virginia?
Sunroom additions in Virginia typically range from $20,000 to $80,000+ depending on size, type (three-season vs four-season), window specifications, and HVAC requirements. Four-season rooms with full climate control and custom windows are priced higher than three-season enclosures. The best way to get an accurate number is a free on-site consultation.
02. What is the difference between a three-season and four-season sunroom?
A three-season sunroom is designed for spring through fall use — comfortable but not heated or cooled for extreme temperatures. A four-season sunroom is fully insulated and climate-controlled, making it a true year-round living space that adds conditioned square footage to your home.
03. Do I need a permit for a sunroom addition in Virginia?
Yes — sunroom additions require a building permit in Virginia, Maryland, and DC. City Deck handles all permitting on your behalf so you never have to deal with county offices or paperwork.
04. Can you add a sunroom to an existing deck?
Yes — we can convert an existing deck into a sunroom or build a sunroom addition that connects to your deck. This is a popular option for homeowners who want to maximize their outdoor living investment.
