Design decision
Why this idea works
A blank wall for projection turns the patio into an outdoor cinema, and modular seating lets you arrange the crowd for movie nights or reset for everyday use. The wall, the power, and the lighting are the systems to plan so the setup actually works after dark.
- The tradeoff
- The layout sets a clear direction, but it also commits the project to fixed relationships. Plan the projection wall, power, and conduit before finishing.
- How to measure it
- Conceptual range: the patio field plus the projection wall and lounge zone figured separately.
On your property
Plan it for your site
Keep the concrete field calm so the projection wall reads clean, and slope the patio to drain. Build the projection wall smooth and true, run power and any conduit for the projector and lighting before the pour, and keep the subtle path lighting glare-free.
- Build the projection wall smooth and true as its own element.
- Run power and conduit for the projector and lighting before the pour.
- Keep the path lighting glare-free and slope the patio to drain.
Before forms are set
Build implications
- Confirm before estimating A smooth, true projection wall.
- Confirm before estimating Power and conduit for the projector and lighting set before the pour.
- Confirm before estimating Glare-free path lighting and patio drainage.
- Measure the site and establish elevations Record boundaries, thresholds, grade changes, utilities, and the dimensions of vehicles, furniture, equipment, or structures that affect the layout.
- Test how the space will be used Check walking routes, turning paths, door swings, working clearances, maintenance access, and the route back to the house or street.
- Resolve drainage, services, and structural support Decide where water goes and coordinate drains, conduit, irrigation, fuel, electrical work, footings, and independent supports before forms are set.
- Define and estimate each concrete element Confirm the slab or footing section, base, joints, edges, and finish, then estimate simple measurable fields separately from steps, walls, drains, and supported features.
Prevent these problems
- Starting with furniture instead of movementDining, cooking, and lounge zones need working clearances and a direct route to the house before the slab outline is fixed.
- Adding services after the pourGas, electric, water, drainage, lighting, and future conduit are easier to coordinate before concrete placement.
- Assuming the slab supports every featureRoofs, pergolas, kitchens, fireplaces, and seat walls often need separate footings or structural details.
Next step
Turn the idea into your estimate
Enter measurements from the property. The conceptual image does not provide a takeoff.
Estimate a similar concrete areaQuestions this idea raises
What makes a good outdoor projection wall?
A smooth, true, light-toned surface with the projector power and mounting planned, since a rough or dark wall degrades the image. Build it as its own element.
Should the power be planned before pouring?
Yes, run conduit for the projector and lighting before the pour so nothing is surface-run later, coordinated with a qualified trade. Plan it early.
- Best when
- Entertainment
- Reconsider when
- Reconsider the idea if circulation, utility coordination, clearances, and independent support for built features cannot be resolved on the property.
- Verify first
- Plan the projection wall, power, and conduit before finishing.
- Professional input
- Coordinate the concrete contractor with utility and feature installers before the pour
