What is Land Assembly?
Land Assembly is a tool that lets you combine multiple individual land parcels into a single site boundary for assessment. Rather than evaluating each parcel separately, you can select adjacent or non-adjacent parcels and save them as one site, giving you a unified view of all the data across the combined area.
This is particularly useful when a development opportunity spans multiple ownerships or title references and you want to assess the total site as a whole.
How to use Land Assembly
Step 1 - Activate Land Assembly mode
Click the Land Assembly icon in the toolbar at the top of the map (the house icon)
The map will enter Land Assembly mode
Step 2 - Turn on Ownership Boundaries
Open The Explorer on the left of your screen
Toggle on Ownership Boundaries to make individual parcels visible on the map
This allows you to see and select individual title parcels
Step 3 - Select your parcels
Hover over a parcel to see it highlighted
Click to select it — it will be added to your Land Assembly selection
Continue clicking additional parcels to build up your site boundary
Each selected parcel will appear in the panel on the right, listed by its title reference
Step 4 - Save as a single site
Once you have selected all the parcels you want to include, click Save
Give the site a name and assign it to a pipeline stage
The combined parcels are saved as one site in your pipeline
Step 5 - Assess as a single site
Once saved, the Assessor updates to show the combined site as a single assessment. You will see the full Assessment panel including Insights and all tabs: Planning History, Policies, Environmental, Ownership, and more, aggregated across the entire assembled site boundary.
💡 LandTech Tip: Turn on Ownership Boundaries before activating Land Assembly mode so you can clearly see where individual parcel boundaries sit. This makes it much easier to select the right parcels, especially on sites where multiple titles overlap or sit close together.
What you see in the Assessor after saving
After saving an assembled site, the Assessor displays data for the combined boundary as a whole, including:
Insights: an at-a-glance summary of key datasets across the full assembled area
Planning History: planning applications on and near the combined site
Policies: planning policy constraints affecting any part of the assembled site
Environmental: flood risk, agricultural land, biodiversity, and other environmental data
Ownership: all title references included in the assembly, listed separately
All other standard Assessment tabs: covering the full assembled boundary
The total area and perimeter of the combined site are shown at the top of the panel.
