We are a full service home remodel company with Handyman services offered. We specialize in kitchens, bathrooms, & basement remodeling. We also offer new builds (and consultations) for ADU's, garages, & decks. Lastly, we have a trustworthy subcontractor group that is licensed & recommended, to provide remodeling aspects such as cabinetry, doors, windows, granite/countertops. Inquire about our concrete services & patios!

"Recently used 4 Season for my kitchen remodel, and am very happy with the end result—it's absolutely beautiful! Together we took the small kitchen from the 1950s to the 2020s, while maximizing the storage capacity. Nick and Russ were great to work with, and I really appreciated their friendly and down-to-earth approach. Nick made himself available for my many questions, his wife was a huge help when it came to making design decisions, and both Nick and Russ were always open to brainstorm ideas for practicality. These are people who take pride in their work and it will show in the end result. Looking forward to working with them again once I come up with the next project :)"

FAQs for addition to existing structure building service projects in Littleton, CO

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
