sport facility architectsYour house became too cramped and there is no opportunity to buy a bigger one? Perhaps you need to think about home addition. It’s a perfect way out to add extra space, adapt the house to your needs, or even increase its value. 
So, to figure out what kind of home addition you need and whether it’ll be a reasonable investment checkup the guide below!

Types and Prices of Home Additions


Mainly home additions are divided into two groups: bump out and build up additions.
• Bump out additions are more expensive than build up ones as they require a new foundation. Plus, you’ll lose the land space and lessen your yard area.
Basically, this type involves extra room on the ground level of your house. 

• Build up additions extend your house upward. It means that you attach an extra room on the second floor or construct a second story itself. It requires a permit as house height regulates by the government. Note that according to the building code in Chicago maximum height of the detached house is 30 ft!  Home addition in Chicago is an advantage but to gain it, we need follow all the rules and laws.

So, to build an addition to your house in Chicago you need roughly $63 000. In general, locals pay from $30 000 to $100 000 for an additional room. In fact, the bottom-line price relies on materials, work complexity, and labor cost. The location of your house plays a part as well. That’s why the cheapest home addition project maybe around $10 000 and the luxury one could rise to $180 000.

Remember that building a house addition requires a permit which costs about $1 500. 

Extra Room

The additional room is built on the side of the house to perform a certain function. Though, some house owners just enlarge the existing room. For example, you could add about 50 feet to the small dining room to create a comfy eating zone or just expand a narrow kitchen.  
Bedroom addition will cost you about $100 – $200 per square foot. The extra bathroom will be more expensive – more or less $350/sf. However, if your key goal is to increase house value, the bathroom is much more significant. It adds up to 25% of the house value. Moreover, take into consideration that selling a house with a single bathroom won’t be that successful. 
Another way to add some space/ improve your home value is to build a “master suite” which is basically bedroom & bathroom construction. So, the average cost of a 250 square feet master suite is $35 000. This price includes foundation, framing, roofing, siding, drywall installation, exterior, and interior paint, flooring, plumbing, lighting, and decorating. Designer and structural engineer services and cabinet installation aren’t included in this cost.
Aside from mentioned rooms, you could append the following additions:

Sunroom or “sun porch” as it’s frequently called, is a perfect addition for homes with a picturesque landscape. It protects from the poor weather and serves as an ideal additional lounge zone. Typical sunroom matches the style of the house, though it isn’t considered to be a living space. You can’t make a bedroom of it according to the building code! However, you could make it cozy and supply it with electricity and central heating.
So, building a 200 sf sunroom will cost you about $20 000. Manufactured patio rooms will be cheaper – circa $11 000 for 150 sf. 4-seasoned rooms’ price (with heating) will be about $400.  

Additional Story

You might add a room on the second floor or build up the new floor from the scratch. The average price for such work equals $250 – $ 400 per square foot. Pay attention that the existing foundation maybe not be prepared for the whole extra story. So, builders may suggest you improve it. This service costs roughly $4 000.
