An Addition Should Never Look Like an Addition

You've seen the ones that went wrong. A roofline that doesn't quite line up. Brick that almost matches. A floor that steps down where the new room begins.

Those problems start on paper. When one firm draws the addition and another builds it, details fall into the gap between them. Luxe closes that gap. The architect, structural engineer, and build team work under one roof, on one contract, with one fixed budget. The people who design your addition are the same people who calculate its loads, tie its foundation to the original, and frame it true.

That's why homeowners searching for home addition contractors near me keep landing on our work. The finished space reads as original construction, not an afterthought.

What's Included

Second Story, Room, Sunroom, and In-Law Additions

Every addition starts with the same question: where should the new space live? Here's how we think about the four most common paths, and the design-build work that comes with each.

Second story additions

When the lot won't let you build out, build up. A second story addition can double your usable space without touching the yard. It's also the most engineering-heavy addition there is. Your existing foundation and framing must carry the new load, and that analysis happens before the design is ever finished.

Room and wing additions

A room addition extends the main floor. Think a primary suite, a larger family room, or an expanded kitchen wing. We design the new footprint so rooflines, floor heights, and sightlines flow from old to new without a seam.

Sunroom additions

A sunroom addition brings in the light without giving up comfort. We build fully conditioned four-season rooms with real foundations, insulated glass, and finishes that match the rest of the home. Not a bolt-on kit.

In-law suites

Private space for parents, adult children, or long-term guests. A bedroom, a full bath, and living space, with a private entrance where the layout allows. Designed for independence and connection at the same time.

Structural engineering, resolved in design

Load paths, foundations, and framing get calculated by the same structural engineer on every Luxe project. Nothing is "figured out in the field," and nothing is decided by people you've never met.

Materials matched, not approximated

We source brick, siding, trim, and roofing to carry your home's lines and proportions into the new space. The goal is simple: a stranger shouldn't be able to find the seam.

Architecture and permits handled

We produce the drawings, run the structural calculations, and manage the village permit process from application through final inspection. One design-build team carries it end to end.

One accountable team

No hand-offs between architect and builder. One phone number, one contract, and one team that answers for the result from first sketch to final walkthrough.

What a Home Addition Costs in the Western Suburbs

Most Luxe home additions run $100,000 to $200,000, depending on size, structural scope, and finish level. You'll approve a fixed, itemized budget before construction begins, so the price you see is the price you build.

A second story addition sits toward the top of that range because of the structural work involved. A sunroom or single-room extension typically sits lower. Additions that include a kitchen or bath carry those costs as well.

Our Process

The Luxe Method, Applied to Your Addition

Every addition follows our four-phase process. Here's how it plays out. You can read the full version on our process page.

01

Step OneVision & Architecture

Walk your space with us. We study the site, the existing structure, and how you live. Then we produce the architectural and structural drawings and manage the village permit process.

02

Step TwoBespoke Curation

We match materials to the original home, brick to brick and trim to trim, and lock every selection into an itemized fixed budget. No allowances, no estimating games.

03

Step ThreeMaster Construction

The same crews execute the structural work. We get the addition weather-tight early to protect your home, then supervise the finish work on site every day.

04

Step FourWhite-Glove Handover

You walk the finished space with us, room by room. Documented, complete, and delivered as drawn.

If your project grows past a single addition, our whole-home renovation team handles it under the same roof.

FAQ

Home Addition FAQs

Straight answers to the questions homeowners ask us most.

How much does a home addition cost?

Most Luxe home additions run $100,000 to $200,000, depending on size, structural scope, and finish level. The band is wide because a sunroom, a main-floor room addition, and a full second story are very different builds. You'll approve a fixed, itemized budget before construction begins, so there's no estimating game at the end.

Will the addition match our existing house?

Yes. That's the core of how we design. The architect on the project carries the original home's rooflines, proportions, and materials into the new space, and the engineer ties the new structure to the old so floors stay level and walls stay true. If we can't source an exact material match, we'll show you the closest options before anything is ordered.

Can we live in our home during the addition?

Usually, yes. Room, wing, and sunroom additions stay outside your living space for most of the build, and we don't open the wall between old and new until late in the schedule. A full second story addition is different. The roof comes off, so many families arrange to stay elsewhere during the structural phase. We'll map this out with you before you commit to anything.

Do you handle the architecture, engineering, and permits?

Yes, all of it. Luxe is a design-build firm, which means the architect, structural engineer, and builder work on one team. We produce the drawings, run the structural calculations, and manage the village permit process from application through final inspection.

How long does a home addition take?

It depends on scope, and we'd rather give you a real schedule than a generic one. A sunroom moves faster than a wing, and a wing moves faster than a second story. You'll receive a realistic timeline with your fixed budget before construction begins, and we build weather-tight as early as possible to protect the home.

Does a second story addition need a new foundation?

Not always, but the existing foundation must prove it can carry the new load. The same structural engineer evaluates your footings, foundation walls, and first-floor framing before the design is finished. If reinforcement is needed, it's designed in and priced into your itemized budget up front, not discovered mid-build.

Tom of Luxe Development, made our home renovation dreams come true! Honestly, if we could, we would give him a 10 star review! Tom and his crew were extremely professional, courteous of our home, paid attention to all the little details and were great with communicating. There were always workers at our house to get the job done as quickly as possible as well. We highly recommend Tom and we are grateful our home was in such great care.

From start to finish our master bathroom remodel was a very positive process. Tom Naglak and his team were totally professional, efficient, and amazingly responsive. They're design conscious and fun to work with. When they say they're gonna do something by a certain date, you can count on being done. Workmanship is top notch. Can't recommend them enough.
