Hi, BarryFletcher 

Based on your description, I have created some measures to achieve the effect you are looking for. Following picture shows the effect of the display.

Measure:

Group =

VAR _location =

    SELECTEDVALUE ( Location[Location] )

VAR _result =

    SWITCH (

        _location,

        "Building 1",

            IF (

                SELECTEDVALUE ( 'Table'[WP Owner] ) = "WP Owner 1"

                    || SELECTEDVALUE ( 'Table'[WP Owner] ) = "WP Owner 2",

                1

            ),

        "Building 2",

            IF (

                SELECTEDVALUE ( 'Table'[WP Owner] ) = "WP Owner 3"

                    || SELECTEDVALUE ( 'Table'[WP Owner] ) = "WP Owner 4",

                1

            ),

        "Building 3", IF ( SELECTEDVALUE ( 'Table'[WP Owner] ) = "WP Owner 5", 1 ),

        IF ( NOT ISFILTERED ( Location[Location] ), 1 )

    )

RETURN

    _result
