Home Additions in Colorado Springs

Room to Grow, Right Where You Are.

Your family has grown, you’re working from home, or you finally need room for the people and things that matter, but leaving the neighborhood, schools, and home you love isn’t the answer. A home addition gives you the space you need right where you already live. For over 30 years, Bob McGrath Construction has built additions across Colorado Springs that match the original home’s structure, rooflines, and finishes so closely they look like they were part of the original plan.
Let’s Expand Your Home

Primary Suites That Give You Your Own Retreat

Add a private bedroom, spa-style bath, and walk-in closet when your current layout leaves no room to unwind.

Second Stories That Double Your Space

Build up instead of out when your lot is tight, without giving up your yard or your neighborhood.

Kitchens & Living Rooms That Fit Everyone

Expand cramped kitchens and family rooms into open, connected spaces built for everyday life and entertaining.

In-Law Suites That Keep Family Close

Create private, comfortable living space for aging parents, adult children, or long-term guests under one roof.

Garages & Bonus Rooms That End the Clutter

Add garage bays, workshops, home offices, or flex space when your home has run out of places to put things.

An Addition That Looks Tacked On Hurts Your Home's Value

Poorly planned additions are easy to spot: mismatched rooflines, siding that doesn’t line up, and floors that don’t flow from the old space into the new. They can also hide bigger problems where the new structure meets the old foundation. We design every addition around your home’s existing architecture and structure, and our licensed and bonded crews tie it all together so the finished space feels seamless inside and out and adds lasting value to your home.

The BMC Way

Simple principles behind every project.

Our decisions are guided by function, context, communication, quality, and the long-term value of the spaces we create.

  2. No Guesswork

    We design the addition around your home's existing structure and style, build a detailed budget, and set a schedule before construction begins.

  3. No Disruption

    A dedicated superintendent manages your build daily, keeping the job site organized and your household running as normally as possible.

  4. No Loose Ends

    We review the punch list together, resolve every item, and don't call it done until your new space feels like it was always part of your home.

Home Additions FAQs

Answers to the questions Colorado Springs homeowners ask most before adding on, from cost and timelines to permits and living at home during construction.

How much does a home addition cost in Colorado Springs?
Cost depends on the addition’s size, type, and finishes, along with site conditions and how the new structure ties into your existing home. A second-story addition and a single-room bump-out aren’t priced the same way. After walking your property, we provide a detailed budget and recommend alternatives where needed to keep your project within your guidelines.
Timelines depend on the size and complexity of the addition, design decisions, and permitting. We build a detailed construction work plan up front so you know what to expect at each phase.
An addition lets you stay in the neighborhood, schools, and home you already love while getting exactly the space you need, designed your way. If you’re weighing both options, we’re glad to walk your property and talk through what an addition would involve.
In most cases, yes. Much of an addition’s construction happens outside your existing living space, and we plan and schedule the work to keep disruption to your household as low as possible. We’ll talk through what to expect for your specific project before work begins.
That’s the goal on every project. We design each addition around your home’s existing architecture, rooflines, and exterior materials, and carry the interior finishes through so the old and new spaces flow together.
It depends on your lot size, your home’s existing structure, local setback requirements, and how you want to use the new space. We evaluate your property and help you choose the option that makes the most sense for your home and budget.
Yes. With decades of local experience, we know Colorado Springs’ building codes and handle permitting as part of the process.
We do. When your project calls for a specialty subcontractor, we find the right expert and supervise their work directly, so every part of your addition meets the same standard of quality.
Yes. Our crews are licensed and bonded, with over 30 years of experience in residential and commercial construction.
