Homeowners Love Their Home Additions In Ashburn, VA

Here’s what homeowners are saying about working with a real professional on their home addition project in Ashburn and surrounding areas.


I can’t say enough good things about MGS!

Chris and the Team were great. I called MGS in to fix a shower and tub installation that another “discount” contractor had completely messed up. 

They came in, evaluated what needed to be done to correct the issue and completed the job in a timely manner and at a great price.

They will be my go-to contractor for any future work I need done.

Chris and team were amazing to work with

From the initial consultation through completion there was great communication, and execution of this project. All options were discussed so that we could make the best decision on the options and layout. 

Our bathroom remodel lasted about a week once all the materials were in. Our home was left spotless at the end of each day, you couldn’t even tell that there was any construction happening! 

Truly professional service, and we are looking forward to our next project with Chris & his amazing crew.

Different Home Additions Cost In Ashburn, VA

While some home addition projects are very affordable and quick, others will bring way more value, but at a heftier price.

There are a lot of additions you can make, but we’ll only discuss the most common ones – the ones homeowners in Ashburn love.

The Cost Of A Bump-Out

As per, it costs between $85 and $210 per square foot to bump out a room. This implies adding a new foundation, new roofing, new walls, and finishes.

Bump-outs are often dining areas in kitchens, mudrooms right at the entrance of the home, or a dressing room somewhere in your master bedroom.

We recommend budgeting between $4,000 to $30,000 for a bump-out.

The Cost Of A Deck Addition

Decks are still home additions, and they’re some of the most impressive upgrades you can get. The average cost to build a deck is between $20 – $50 per square foot.

This addition means adding a deck frame, the decking materials, the railing, lighting, and then any other extra feature you might want on your deck.

On average, decks cost between $10k for a small wood deck to over $50k for a large, two-levels composite decking with the best railing and lighting systems available.

The Cost Of A Walk-Out Basement Addition

Walk-out basements are beautiful and functional but expensive because of all the labor they provide. Walk-out basements cost $20,000 and can go up to over $50,000 for a larger space equipped with all the bells and whistles.

However, the appraised value of the finished basement space is generally 50% to 60% of the value of the main level square footage.

So for every $1.00 spent on a basement remodel or finish, you’ll get a return of $0.79 when you sell. Maybe not the best investment, but a decent one.

The Cost Of A Garage Addition

The average cost to build a garage is around $40 to $50 per square foot for a basic construction.

As a result, the average one-car garage will run between $12,000 to $17,000, and a two-car garage $18,200 to $25,000. If you want a three-car garage (36 ft x 24 ft) will cost around $44k.

Whether it’s a detached or attached garage, this investment will be well worth it.

The Cost Of A Sunroom

The typical cost of building a sunroom ranges from $27,000 to $58,000. On average, this covers materials and labor, up to around $42,500. You will be shelling out an amount between $130-$330 per square foot when you hire a contractor for construction or about an estimated figure of roughly $230 per sq ft.

Sunrooms can also be prefabricated; you’ll just have to install them. These are more affordable, but you’ll make a better investment by building a permanent structure.

What To Keep In Mind For Your Home Additions Cost In Ashburn, VA

The home addition market is filled with shoddy contractors building additions with no sense of responsibility, overcharging for a superficial service, and even vanishing after they get your money.

Here are three things worth remembering when budgeting for your home addition project.

If you don’t own three cars, why get a three-car garage? Or if you already have a large kitchen with a dining room, why get a kitchen bump-out? One key factor when budgeting is figuring out what it is that you truly need and what it is that you want.

In a nutshell, don’t overspend on features or upgrades that you won’t take full advantage. On the same note, don’t underspend if you feel like you really need something in particular.

Preparing for unforeseen events when remodeling or building is crucial.

Mold, mildew, and plumbing difficulties are all common in many households, and there are high chances you’ll discover these issues. They’ll also need to be addressed quickly.

Setting aside an extra 20% of your project cost gives you a safety net in unforeseen circumstances. It’s always better to be safe than sorry!

As we said, the remodeling market is full of bad practices and contractors going after your money.

To make sure you’re calling the right shots, do your research a choose a reputable contractor. Read reviews online, check out their previous work, get a quote from them, and ask them plenty of questions to see how invested they are in winning you as their client.
