You can develop a parcel with a plausible building, you can leave the parcel as is, or you can demolish existing conditions. A plausible building is a low level of detail (LOD1) schematic building. You can generate a plausible building automatically by assigning a building type to a parcel, or you can create a plausible building by drawing individual building spaces. You can also edit the individual floors of an automatically generated building. In addition to drawing building spaces, you can draw and edit surfaces. You cannot develop a parcel in the existing scenario. See Work with plan scenarios to learn more.
Assign building types
When assigning a building type to a parcel, a plausible building is generated. The form of the plausible building is based on the underlying zoning or land-use parameters and the space-use types assigned to the building type. To generate a plausible future building on a parcel, all of the following are required:
- The parcel must be located in a zoning or land-use boundary with sufficient parameters to define a plausible building (or at least parameters applied as overrides on the parcel).
- The parcel must have a building type assigned with space-use types and a stacking plan for the floor plates of the building.
- The parcel must have a valid combination of parcel shape, size, and zoning or land-use parameters; otherwise, a building may not be possible or feasible (for example, if a parcel is too small to support a large building).
Assign a single building type
To assign a single building type to a parcel, complete the following steps:
- Open the plan editor.
- Click Development
in the header to switch to development mode. - Click a parcel in the view.
- Click the Modify drop-down menu in the Planned development on selected parcels section of the side panel and choose Apply building type.
The side panel lists the available building types. If you select a parcel with an assigned building type, it is highlighted in the list.
- From the Select building type side panel, click the building type name to assign to the parcel.
- The building is updated in the view.
- Existing buildings and trees intersecting the selected parcel are demolished. See the Demolish existing conditions section below for more information.
Assign a building types mix
To assign a building types mix to multiple parcels, complete the following steps:
- Open the plan editor.
- Click Development in the header to switch to development mode.
- Select the parcels to which the building types mix will be assigned.
To select multiple parcels, press the Shift key while selecting parcels or use the Advanced selection tool
on the workflow toolbar at the right of the view. To deselect a parcel from a group selection, press the Alt key while clicking it in the scene view. - Click the Modify drop-down menu in the Planned development on selected parcels section of the side panel and choose Apply multiple building types.
The Apply multiple building types side panel appears.
- Add building types using the Add building Type drop-down menu in the side panel.
- Define a percentage for each building type.
- The percentage represents the probability with which the corresponding building type is assigned to one of the selected parcels.
- If the sum does not equal 100 percent, the percentage values are redistributed automatically to equal 100 percent when you click Apply multiple building types.
- Click Apply multiple building types at the bottom of the side panel.
- The view is updated and shows the parcels with the configured building types mix.
- Existing buildings and trees intersecting any selected parcel with a building type applied are demolished automatically. See the Demolish existing conditions section below for more information.
Note:
- The assignment of the building types changes every time you apply the same mix of multiple building types.
- In the allocation process, only building types that comply with the underlying zoning or land-use regulations are applied to the selected parcels. This may affect the resulting building types mix.
Draw and edit spaces
You can do the following when drawing and editing spaces:
- Edit the building spaces of generated plausible buildings.
- Draw additional spaces on or next to generated plausible buildings.
- Design custom buildings by drawing new building spaces.
- Improve the surroundings of the developments with surfaces.
- Duplicate buildings.
As with building spaces, surfaces have a space-use type assigned and count toward metrics. Surfaces do not count toward zoning regulations such as coverage or number of dwelling units. They can count toward floor area ratio (FAR) if this is specified in the surface settings. Surfaces are always draped to the terrain and have no height.
Draw new building spaces
To draw new building spaces, complete the following steps:
- Open the plan editor.
- Click Development in the header to switch to development mode.
- Optionally, demolish existing buildings and trees where necessary.
See the Demolish existing conditions section below for more information.
- Select the parcel where you want to draw a new building space.
- Click the Edit spaces tab in the side panel.
The blue header bar with the spaces editing tools appears.
- Click Draw new building space
. - Draw a building space on the map.

—Duplicate the building where the selected building space belongs. - Edit building elevation
—Vertically align the entire building where the selected building space belongs.Note:
The tool automatically updates the floor numbers and the building height. Floors that are pushed to underground are automatically excluded from the gross floor area (GFA) and FAR calculations; floors that are raised from underground count toward GFA and FAR. Uncheck the Change ground floor check box to disable this automatic update of the ground floor (for example, to adjust the building in uneven terrain). When using the tool, the ground floor is highlighted in blue.
- Remove
—Remove the currently selected building space.
- Transform
- Edit the parameters of the selected building space in the Selected spaces section of the Edit spaces tab in the side panel. Choose from the following options:

Generate buildings from footprints
You can generate building spaces by uploading building footprints. See the Draw and edit spaces section above to learn how to modify and edit building spaces.
To generate building spaces from footprints, complete the following steps:
- Open the plan editor.
- Expand the drop-down menu named after the plan and choose Configure plan.
The plan configuration opens to the general plan settings tab by default.
- Choose Spaces from the Development drop-down menu.
- Choose the scenario that will receive the building spaces from the scenario drop-down menu.
- Click Upload footprints to open the From feature layer dialog box.
- In the Item step, search for the ArcGIS Enterprise layer that contains the footprints, click the layer, and click Next to continue.
- In the Sublayer step, select a sublayer, and click Next to continue.
- In the Data step, choose the building type to be applied to the imported footprints, and click Next to continue.
The buildings being generated ignore the underlying zoning or land-use parameters. For every space-use type that is part of a building type, the maximum number of floors is built as configured on the building type.
- In the Validation step, review invalid features in the Errors table if errors are detected. Correct the errors in the source data and click Refresh. If all features are valid, click Next or wait for 5 seconds to start the import.
- In the Import step, all features are imported. Click Close to close the dialog box.
Building spaces are only generated for building footprints that are completely within the study area and whose centroid intersects with a parcel. Underlying parcels are automatically demolished.
Note:
- You can upload footprints to parcels that are already developed with future buildings. To replace those buildings, ensure that you first reset the respecting parcels before you upload footprints.
- The footprints are converted to the coordinate system of the urban model if the coordinate systems don't match.
Validate buildings using zoning regulations
You can validate the new buildings using the zoning regulations in the current scenario. You can do this by displaying warning labels in the map view or by inspecting the building regulation side panel. See Zoning regulation management to learn more about zoning regulations.
