"My husband and I had several appointments with different contractors. When we met with Terry, we both felt he was very knowledgeable in all areas, and had very good pricing. Needless to say, we chose Newland Construction. From day one, we felt comfortable and at ease. Renovation Project: 1. Moved the small kitchen to our large dining room. 2. Moved dining room to former kitchen ( swapped rooms) 3. Dining room: (former kitchen) removed wall for open concept 4. New flooring 5. Stairs: replaced carpet with laminate, replaced rails 6. Living room: Added a window seat with storage 7. Living room: Added entertainment wall with shelving 8. Living room: Added modern fireplace 9. Added windows, moved sliding glass door WE LOVE THE FINISHED PRODUCT!! The project was right on schedule (5 months) and we didn't go over budget. As it is expected to run into a few snags during ANY renovation, Terry and John were very responsive and quick to resolve any issue. They were on top of the problem, and resolved with excellent results. We get a ton of compliments on our home. Thank you, Terry, John and your crew. You've exceeded our expectations. Highly recommended!!"

"We recently completed an extensive remodel of our home—new windows, fresh exterior paint, two fully updated bathrooms, new interior doors, upgraded flooring, and a complete transformation of our primary bedroom. The results have exceeded our expectations, and we couldn’t be happier. This level of satisfaction was only possible because of the personal and professional attention from David Eskin. From our very first meeting to his final message saying, “We are done,” David was attentive, thoughtful, and full of professional recommendations we would never have considered on our own. He kept us informed at every step—through each hiccup, process, and inspection—so we always felt confident and included. What began as a plan to simply “fix the house up until we find another home” has turned into “we’re staying,” because the craftsmanship is extraordinary, and it truly feels like home. We will be using Horizon for Round 2!!!"

"hired Frontier Remodeling for a home remodel, and it was a mistake. I selected them based on Aron telling me his guys were skilled, focused on quality, efficient, and clean. I experienced none of that. Work progressed slowly for 3 months. They rushed and cut corners at the end so they could finish and get paid. Quality was very poor, workers did not respect my property, and my new home was an unorganized filthy mess for 5 months. The only thing about Frontier Remodeling that was organized and punctual was Aron asking for progress payments. In the end, I had to hire other contractors to correct a fair amount of work."

FAQs for addition to existing structure building service projects in Mission Viejo, CA

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.
