Screened Porch Addition, Overland Park

Project Story

All Under One Roof designed & built a 324 square foot screened porch addition on the back of an Overland Park home: 18 by 18 feet, with a vaulted tongue & groove ceiling, skylights, a paver floor & a matching paver patio outside. The porch was engineered & permitted through the City of Overland Park in 2017.

Drawn with the homeowners

The design went through several rounds in 2016, with the homeowners marking up each set, before final drawings with construction details were issued. Engineering followed in March 2017 with a foundation plan, a grade beam drawing & roof framing, & the contract was signed in June 2017.

A grade beam under the porch

The porch sits on a reinforced concrete grade beam, specified at 12 inches wide by 36 inches deep in 4,000 psi air entrained concrete & doweled into the existing house foundation, with a short stem wall above it to keep the framing off grade. A drain pipe runs through the grade beam & out to daylight, so water that reaches the porch floor has somewhere to go.

Framing & roof

The new roof ties into the house on a double LVL ridge beam, which meant removing the old roof over the kitchen bay window & reworking the siding around it. Rafters are 2x6 Douglas fir at 12 inch centers, with ice & water shield across the entire roof deck, shingles matched to the house & fixed Velux skylights with Low E glass. Inside, the ceiling is tongue & groove pine, & the posts, beams & chair rail are smooth cedar. New siding & trim match the house.

Floor & screens

The floor is concrete pavers on compacted gravel & a sand bed, laid to a 1 percent fall, with floor drains at the low edge tied into the drainage under the pavers. The walls use a tensioned screen panel system rather than stapled fiberglass screen, split at the cedar chair rail into upper & lower sections. Two full view storm doors open to the yard, & the gable end is glazed with clear polycarbonate above the screens.

Power & light

The porch has a ceiling fan with a light kit, dimmable recessed lights, outlets & a TV connection, plus flood lights & soffit lights over the outside patio, each on its own switch.
