Consider separate access to the ground floor in higher density development to provide work from home opportunities.
The separate access allows people to receive clients and co-workers at their home without needing to allow them to walk through the living areas of the house. This provides the opportunity to work from a home office while still maintaining a professional environment. Certain professionals would find this a very attractive feature, especially in "high density" environments where leasing a separate office space might be prohibitively expensive.
In some areas, there may also be tax implications. In the US a home office has to meet certain requirements to be treated as a work space for tax purposes, and a separate entrance may be one of them (I don't know for certain).
Also as Ben Kovitz pointed out in the comments, the sentence would have been easier to understand if the compound adjective had been properly hyphenated as work-from-home.
