Before she attacked it with paint and plants, it was an empty space and "boring, filthy and depressing".
Her first project was to paint a mural of a cottage, with lace from an old curtain providing the fretwork on the veranda.
While it probably took her longer to cut out the lace than it would have taken to paint it, it gave it texture and proved effective.
"That was a cunning plan," she said.
The next mural was much larger and depicted a waterfall from Te Urewera National Park.
That was a "big scary job" as it required scaffolding.
She had to keep climbing up and down as she could not see what she was doing.
She completed the mural over a few months.
The multitude of colourful plants were in pots as she liked being able to shift them around and change the look.
Some visitors were "gobsmacked" when they saw it, she said.
She is now preparing for an exhibition of her paintings, entitled "April Foolery", which runs from April 2 until April 15 at Gallery Picture Framing.
It is her first solo exhibition.
She also does some set painting for the Oamaru Repertory Society.
Despite no formal art training - "I wouldn't say I was even self-taught. It's just something I seem to be able to do" - she was "having a ball".
"There's nothing clever about it. It's only paint stuck on a wall, isn't it?"
