Custom Sunroom Design & Build for Washington, DC Area Homes

A custom sunroom is a great addition to any home—it’s a place where the indoors meet the outdoors and serves many purposes, from eating breakfast and watching the sunrise to relaxing with a good book to watching summer storms at night.

Although sunrooms or four-season rooms aren’t a necessity the way bathrooms and kitchens are, they are beautiful luxuries worth considering for your DC metropolitan area home!

Considerations for Custom Sunrooms & Four-Season Rooms

A design-build company will help you with all the details, but in general, sunrooms are extremely customizable and can look exactly the way you want them to. Factors to consider and discuss with your design and installation team include:


Southern and eastern facing sunrooms get the most heat and sunlight. If you want to grow plants, you’ll want it pointed in one of these directions. Rooms that face north will get less sun exposure and be colder in the winter—but they’ll also face less heat gain during the summer, making it easier to maintain the temperature.


Do you need ventilation? Whether you’ll have screens, windows, or skylights is up to you, and we’ll be able to discuss with you the best option based on your needs and design preferences.

Heating and cooling

Will your sunroom require heating and cooling? If so, it will probably require an individual heating and cooling system with its own thermostat. Requirements will differ from other areas of the house, so the space’s heating and cooling system must be planned in advance.


Ideally the room should not be constructed on piers, with the underside of the floor exposed to the weather – it will be much colder. Preferably the foundation will consist of proper continuous masonry, with an insulated crawl space, especially if you’re using the sunroom as part of your living space. If you want to display plants in the room, it is wise to have an insulated concrete slab that allows for damp conditions and floor drains.
