"Guy and his team did an amazing job, they were able to work with my budget and get everything done (and more) in the original timeframe we discussed. Guy came up with an effective and beautiful redesign of my bathrooms in our first meeting. This was my first remodel, so I was a bit nervous but he gave me advice on everything along the way. He was helpful, kind, and patient through the entire process. Highly recommend!"

"Great experience! We used Amaral Construction to paint our kitchen cabinets and install new countertops, sink, faucet, and garbage disposal. Edgar and his teams did great work, always showed up on time, and were very transparent in their work. They finished 3 days early to the quoted schedule and had less than 1% cost growth! Edgar chatted with me before making any decisions and was super responsive via email, text, and phone. I also appreciated never being pushed to add more work or increase the scope of the project. Edgar listened to our wants, gave advice, and went forward with our choices to a T. Thank you Amaral Construction!"

Addition to existing structure building services FAQs
How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.
Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
