This glimpse, we believe, will help you appreciate the many distinct advantages offered by John Christopher Construction.

In this article, we’ll be discussing:

Why Choose Design and Build for Home Remodeling & Expansion?

The easy answer to this question is simplicity. By handling the entire process ourselves, we offer a single point of responsibility, smoother communication, and fully integrated design and construction. All working together under one roof. Bear in mind, when we say we do it all, we mean everything, including ancillary services such as permit acquisition, structural review, and subcontractor coordination.

But be prepared for a windfall to match all that convenience. You see, the improvements we make almost certainly will boost property value, often by significant margins. This bonus applies to any type of construction work, including ADUs. Which, as Orange County’s premier ADU builders, we’re particularly skilled at creating.

You’ll be pleased to know that our full-service approach gives homeowners complete flexibility when it comes to the improvements we make. With John Christopher Construction as your home rebuild partner, we can remodel existing spaces, expand spaces, add new levels to a structure, or build entirely new units. Wherever your dreams take you.

No problem — that’s right up our alley. With extensive experience in this area, John Christopher Construction can add a new bedroom, home office, guest suite, or family room. True, there’s a lot to orchestrate. But as room addition contractors that do it all, we capably manage the many challenges associated with this process, including structural integration, foundation/footing work, tie-ins to existing home systems, cost per square foot estimates, and permit acquisition. It’s an effort you’ll more than appreciate, because when we’re through, you’ll gain the comfort of increased functional space, a better fit for your current lifestyle, and a higher resale value for your property.

Second-Story Home Additions: Go Up, Not Out

Sometimes it’s not practical or possible to expand your home’s horizons on the ground level. For these situations, John Christopher Construction offers extraordinary second story additions. In fact, we consider ourselves the best contractors for second story additions in Orange County. If your property is situated on one of Orange County’s limited size lots, this could be the ideal option.

As design and build contractors, we handle all considerations such as engineering (structural load and earthquake code), stairs and egress, and roof removal and replacement. Moreover, we offer all the usual benefits of a top-to-bottom provider – coordinated structural, plumbing, electrical, and roofing work.

Adding Bathrooms & Bedrooms

No matter what type of room we’re adding, John Christopher Construction takes into account the full gamut of variables throughout the design and build process. These variables include square footage, plumbing rough-in, ventilation/natural light, finishes, and permit acquisition.
