AI Exterior Additions — Fences, Walls, Driveways, Garages & More
Roomagen Exterior Additions adds a fence, wall, driveway, path, retaining wall or building, such as an ADU or garage, to a property photo, or replaces the existing one: 18 types, usually in under a minute, at 2 credits per image.
A new fence, driveway or garage changes how a property is used and how buyers picture it, but building one is a large commitment: contractor quotes, often a permit, and weeks of work depending on the structure and the weather. Buyers viewing a property without one cannot easily picture how a privacy fence, a paver driveway or a carport would sit with the home's architecture and lot layout. Roomagen AI renders any of 18 exterior addition types onto your existing property photo, as a new addition or in place of the one already there, in under 90 seconds at 2 credits per image.
No credit card required. Results usually in under a minute.

AI Processing

ADU or guest house, garage, carport, shed and greenhouse, built in materials that match the home.
Who Is It For?
Real Estate Agents
Show a property's potential by adding a privacy fence, a new driveway, a garage or an ADU to listing photos. Buyers can picture the upgrade before they visit; label the images as concepts where your market requires it.
Contractors & Builders
Show clients the fence, wall, driveway or garage you are quoting on a photo of their own property. A proposal built on the homeowner's own exterior photo is easier to discuss than a verbal description or a generic portfolio image.
Homeowners
Compare exterior addition options on a photo of your own property before you build. Test a vinyl fence against a stone wall, or see how a carport or a garden shed would sit next to the house.
Common Use Cases
Listing Enhancement with Outdoor Potential
Add a privacy fence, a paver driveway or a garage to listing photos to show buyers what the property could look like.
Contractor Proposal Visualization
Include photorealistic exterior addition renderings in construction proposals showing the exact structure on the client's actual property.
Homeowner Addition Comparison
Test multiple exterior addition types on the same property photo at 2 credits per rendering.
Unlike physical exterior construction, which needs a contractor quote, often a permit and weeks of building, Roomagen previews all 18 exterior addition types on your actual property photo before any financial commitment. Architect plans and 3D rendering services add design fees and weeks of lead time before anything is built. Roomagen processes at 2 credits per image on your existing exterior photo in under 90 seconds.

Choose Fencing & Walls, then one of 8 types, from a wooden privacy fence to a brick wall. The AI places it on the property at a realistic scale, with posts, caps and shadows that match the photo's light.
Yes. Under Hardscape, choose a paver, concrete or cobblestone driveway, a walkway or path, or a retaining wall. If the photo already has a driveway, choose Replace the existing one and the old surface is rebuilt in the new material.
Yes. Under Buildings, choose ADU / guest house, garage, carport, shed or greenhouse. The AI renders the building on the lot at a realistic scale, with a roofline and materials that match the home.
