SUNROOMS & PATIO ENCLOSURES

Three-season rooms

Create a glazed seasonal room that offers more shelter than screens alone. Choose how the panels open and how the room connects to the house while keeping its seasonal comfort limits clear.

START WITH THE DETAILS

What goes into
the work.

Measure the footprint and wall height. Record the existing slab, roof, drainage and intended seasons of use.

Typical scope to confirm

  • Verify supporting slab or deck and roof suitability
  • Lay out glazing, screen panels and access doors
  • Detail flashing, drainage and exterior connections
  • Select flooring suitable for expected temperature and moisture exposure

Make it specific to your project.

Enter the amount of work and choose the details you know. Your choices follow you into the Project Builder.

LOW / MIDDLE / HIGH REFERENCE

Low$80per sq ft
Middle$155per sq ft
High$230per sq ft

Low and high are published reference endpoints. Middle is their arithmetic midpoint, not a quoted average, product tier or firm price.

Match the reference scope first
  • Confirm Use before applying this reference to your quantity. The source row is a three-season enclosure, not a conditioned room or screening-only scope.

The figures above remain the source reference. They do not price these selections or a complete installed project.

A planning reference for this service only. Selections, local labor, access, quantities and existing conditions need Coastal’s review. Do not add overlapping whole-project and component ranges.

KNOW WHAT COMES NEXT

From first idea to finished work.

  1. Plan the scope

    Define seasonal use and limits before choosing the enclosure system.

  2. Prepare and approve

    Review supports, drainage, design, approvals and the selected enclosure system.

  3. Complete the work

    Build approved supports and enclosure, then coordinate doors, finishes and any utilities.

  4. Review and close out

    Check weather management and operation; review the approved use and care.

PERMIT PLANNING

Check the scope and jurisdiction

Size, height, attachment, use and location determine approvals. Edmond lists exceptions for some small detached structures and fences; OKC asks owners to check shed scope before construction. Confirm setbacks, easements and utility work too.

  • Attached or substantial new outdoor structure
  • Work outside local size/height exemptions
  • Property-line, easement, utility or drainage impacts

ENGINEERING & DESIGN

Engineering required for these conditions

Edmond requires an engineered footing design for the footprint additions covered by its alteration/addition checklist. Other locations and existing-space conversions need scope-specific structural review.

  • An Edmond footprint addition under the city alteration/addition checklist
  • New loads on existing framing or foundations
  • Unusual soil conditions or nonstandard structural details

Confirm requirements with the city or county responsible for the property before work begins. The address, exact scope and adopted code determine the final requirements.
