We use 3D models to help us understand new building plans. These models show us the size and design of buildings. We use a tool called VU.CITY for this. VU.CITY has a detailed model of Greater London, including Harrow.
We use it to see how new buildings will look and fit into the area. We charge £737.00 (including VAT) to process and check 3D model files. See our schedule of fees (category O).
Requirements for a 3D submission
To propose a major development in Harrow, you must:
- submit a digital 3D model. (This forms part of pre-application talks).
- discuss your submission in the pre-application meeting.
Our officers can withhold responses until they review the digital models.
Various application types:
- Category A - Strategic Development. All submissions in this category must include a 3D model.
- Category B - Large Scale Major Development. All submissions in this category must include a 3D model.
- Category C - Major Development. Developments of four storeys and above must submit a 3D model.
- Category D - Outline Reserved Matters Major Development. Developments of four storeys and above must submit a 3D model.
A 3D model is optional but recommended if:
- a development is in a sensitive area
- a development is in a conservation area
- a development may affect the townscape.
Other application types:
- Category E - Minor Development 1
- Category F - Minor Development 2
- Category G - Minor Development 3
- Category H – Outline Reserved Matters Minor Development
- Category I - Small Scale Development
- Category J - Householder
- Category K - Heritage.
Sharing your 3D model with us
- If you have a VU.CITY subscription, models can be shared to us within the VU.CITY Cloud Platform.
- If you do not have a VU.CITY subscription, 3D model files can be sent in a .FBX file format.
- Please share all models with the planning case officer. You should also share the models with the urban design officer.
You may want to get a VU.CITY licence. It will allow you to test your schemes in a 3D context as part of the design and pre-application process.
Applicants can be granted temporary access to VU.CITY. They can then import, view, and share a model link with us. Find out more about temporary access on the VU.CITY website.
Sending a model file directly
VU.CITY is a townscape tool for assessing design and impact of scale. It is not for large, detailed BIM models. It needs a simple model with no internal or structural detail.
The model should be submitted as follows:
- Be geolocated in OS space in metres (m) units
- Have a low polycount (recommended less than 65,000 vertices)
- Be below 128 MB
- Be saved / exported in FBX file format
- Named with your application reference number. Any revisions must be labelled
- Submitted with the downloadable form (see below)
- Send your .FBX files to your planning case officer. This should be with your completed 3D model submission form (PDF 312 KB). For queries, contact: planning@harrow.gov.uk.
For guides on geolocating and preparing a model for import, see below:
