Real numbers for real Maryland porches and sunrooms.
Most contractors won’t put prices on their website. The reason is simple: a number on a page is a commitment, and most contractors don’t want to commit until they’ve had a chance to read the customer in person.
KP works differently. The prices below come from porches and sunrooms we’ve actually built across Charles, Prince George’s, and St. Mary’s counties. They’re tied to real sizes, real materials, and real county requirements. If your project looks like one of these, it’ll cost about what these cost. If it doesn’t, the consultation is where we figure out why.
No bait pricing. No mystery quotes. Just the math, the way it actually works.
“KP was the only team that gave us actual numbers upfront — no sales pressure, just clarity.”

When This Tier Is the Right Fit
| KP Breeze | KP Solaris | KP Aurora | KP Solstice | |
|---|---|---|---|---|
| What It Is | Screened porch | Three-season porch with Eze Breeze windows that open to 3/4 screen | Sunroom that grows from three-season to four-season | Four-season sunroom, fully conditioned |
| Best Use Season | Late March through early November | Late March through November, with added comfort on cold or rainy days | Three to four seasons, depending on upgrades | Year-round |
| Advantages | Most affordable way to get bug-free outdoor living. Fast build. The porch most homeowners actually use most. | Eze Breeze opens to 3/4 screen in summer, then closes to block wind and rain in shoulder seasons. Keeps you comfortable on rainy days when blowing rain would normally drive you inside. Stretches your usable months without committing to a full sunroom build. | The widest range of options on the page. Can be built as a Cat III room or upgraded all the way to Cat IV with HVAC. Aesthetic finishes (PVC wraps, recessed lights, LVP flooring) come standard. | True four-season comfort. Built like the rest of your house from the studs out. Insulated glass, drywall throughout, dedicated HVAC, luxury trim. The room you forget you’re in an addition. |
| Disadvantages | Open to the weather. Bugs gone, but cold air, wind, and rain still come through. Not a year-round room. | Eze Breeze windows aren’t insulated glass. The room won’t hold heat or cool air the way a sunroom does. Not designed for HVAC. | More choices than the other tiers, which means more decisions to walk through at the consultation. | The biggest investment of the four tiers. If you’re not actually going to use the room year-round, you’re paying for capability you won’t use. |
| Best Fit For | Homeowners who want to stop being driven inside by mosquitoes and aren’t trying to use the porch in January. | Homeowners who want more shoulder-season comfort than screens give them, but don’t need a heated and cooled room. | Homeowners who want the freedom to build the room they want — anywhere from a finished three-season porch to a fully-conditioned four-season sunroom. | Homeowners who want year-round comfort and the extra aesthetic upgrades |
| Not the Right Fit If | You want to use the room when the weather is cold or wet. | You want the room heated or cooled beyond a space heater. The shell isn’t built for full HVAC. | You want more options than what is offered by Aurora | You do not need all the aesthetic upgrades |
