This requires removal of center post, which is a structural element. So there are the following requirements:

• This must be done by a licensed general contractor, who we can refer
• A building permit
• A beam that is strong enough to support the entire span. This must be spec’d by an engineer.

Prices vary for this type of work based on many factors, including:

• Siding material (brick vs. vinyl), etc.
• Foundation situation (center portion of foundation must be removed)
• Electrical work
• House setup (eg. is opening on a gable end?)
