Frequently Asked Questions About Whole Home Remodeling

Curious about what to expect? Here are answers to some of the most common questions homeowners ask about building a home addition.

What types of additions do you build?

We handle a wide range, including primary suites, family rooms, guest suites, home offices, and second-story expansions, all designed to match your existing home.

How long does a home addition take?

Most additions take 3 to 6 months, depending on size, complexity, and permitting timelines. We’ll walk you through every step before construction begins.

Will the addition match the style of my current home?

Yes. We carefully select materials, rooflines, and architectural details to ensure the new space looks and feels like it belongs.

Do I need architectural plans before we start?

Not necessarily. We can work with existing plans or help develop them with our design and drafting partners as part of the planning phase.

Our Custom Process

1 | Discover & Plan

We start with a conversation about your goals, style, and investment range. During this phase, we listen carefully, gather details, and offer early insight into feasibility and approach.

2 | Build & Manage

Once plans are finalized, we bring together trusted tradespeople, realistic timelines, and hands-on project oversight. You’ll receive consistent updates, expert coordination, and support with material selections.

3 | Deliver & Support

When construction wraps, we walk through the finished space together to ensure every detail meets your expectations. You’ll receive documentation, warranty coverage, and continued support long after the dust settles.

What Our Clients Think

"I have been through several remodeling projects over the many years. This was perhaps the most complicated since we had to retrofit the house for an elevator. Warren is an excellent problem solver who worked through every obstacle. He communicates every step of the way and responds to texts and phone calls within a reasonable amount of time. I needed this remodel to go smoothly, and Warren made it happen. Results are great."

Lincoln Heights Client

What Our Clients Think

"Perfect results on my project; Warren was my contractor and now my friend. Never an issue he could not fix. Great subs, and above and beyond follow-up before and after the project ended. Would recommend to everyone I know and would hope to have another project with Warren. I always told Warren that he may have bigger projects and clients than me, but no one is happier."
