"Simply put, Bill builds from the heart. We had a major renovation that entailed reconfiguring the entire 2nd floor with the addition of a bed and bathroom. We also had our 1st floor reconfigured with a wall removal and a master ensuite established. With a project of this size there are challenges and Bill and his team worked as professionals through each one. The quality of build that Bill and his team establishes is top notched and stands with the best in the business, We did have some hurdles with finishing details, however, with continued communication with Bill and some realignment, the project came out better than our expectations. We're very happy with our overall results."

"The carpenter that did the job (Adam) was amazing. He had to expand the space for one window, narrow the space for another, and repair much cedar siding that had rotted away due to water damage. He also reshaped my patio door so it would close and lock more easily. He is a very talented carpenter and I have no qualms about highly recommending him."

Henry Showah Construction can skillfully design and remodel all types of projects. We take pride in our attention to detail. Please give us a call to set up an appointment.

"We contracted Henry as our GC to lead a 175K addition/renovation of our home. We added a master suite (w/ walk-in closet), another bedroom, a play/rec-room, and a workshop. We also took down the walls of an existing room to open up the common areas and built a hallway of pocket doors. We found him to be a great communicator. His subs were professional and courteous. Highly recommend him for others and would be happy to hire him again for future projects."

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.
