How Long Does it Take to Build a Four Season Room?


Construction of a four season room is like a home extension project. There are many factors to consider when adding a wing to your existing home. However, the overall scale of the four season room project is much less complicated than a full fledged addition.

To estimate how long building a four season room takes, you have to include the consultation process. In addition to the work itself, there is a lot of planning that needs to take place.

Consultation Stage

This is very flexible. It depends on the scope of the project and the clarifications you need. For a simple project, the time taken is usually 2 hours.

For best results, include all decision makers and affected family members in the conversation.  Almost every family member will be using the room, and may have valuable insight.  Since the room will be customized to specific requirements, it’s better to get everybody involved in the beginning rather than create changes later.

There are lots of details to hammer out – color and design of the room, frame materials and the type of glass for example. Making group decisions in the drawing stage helps set a clear goal and vision for the work.  This makes the contractor’s job easier and less time consuming down the road.  It also saves from wasting time or expenses on additions and alterations later.

This process takes about 2 to 3 hours at most.

Building stage 

The average four season room takes about 8 to 10 weeks to build.  Of course unexpected variables affect the speed of production. Wondering what kind of unpredictable variables we mean?  Here are some examples:

  • Building Permits – Each state has its own building laws regarding construction of four season rooms. If the local government office is backed up, so will be your permit.  Anticipate delays with permitting and file as early as possible.
  • Heating and Cooling Systems – Your home furnace or centralized cooling system cannot be linked to your four season room. In which case, you have to install new heating and cooling units. Installation of ducts or systems has to be added to construction time.
  • Insulation – Installing additional insulation to optimize heating and cooling functions is necessary. Insulated glass on its own might not be that effective. This creates another time consuming, but necessary step. Remember, unlike other rooms in your home, the four season room is open to external elements all the year around.

Ask your contractor to set project bench marks and a tentative finish date.  Check in regularly to get progress updates.  Delays arise.  It’s better to have all of the information so that you can hold your contractor accountable for their commitments to finish in a timely manner.
