Clyde residents Bob and Nicky Lines organised groups of people to volunteer their time and skills during the weekend to landscape the Falconers' quarter-acre section.
Businesses also got behind the project, which aimed to give Mr and Mrs Falconer enjoyment and relaxation during the time they have left together.
Mr Falconer (46) was diagnosed with cancer last April and two months ago was told it was terminal.
The Falconers were overwhelmed with emotion yesterday as they watched their bare garden transformed into the outdoor area of their dreams.
"It's quite amazing because it's what we would have done ourselves.
"Even people walking past throughout the weekend came in to help when they heard what it was about," Mrs Falconer said.
Timber, paving stones, plants, and other materials were donated by local firms and each volunteer made the most of their particular skills, whether it was hard labour or baking.
"We are just so thankful," Mrs Falconer said.
The couple moved to Clyde about four years ago.
Originally from Mosgiel, they bought their Clyde section with intentions of building a holiday home, but decided to settle permanently instead.
Mr Falconer helped design the house but had a heart attack almost immediately after it was completed.
Landscaping was moved off the agenda as Mrs Falconer worked and Mr Falconer - a contractor by trade - recovered.
Cancer was a further setback, although for a time the Falconers thought they had jumped that particular hurdle.
When first diagnosed, Mr Falconer had surgery and initially his prognosis was good, although two months later the cancer came back.
Mr Falconer underwent about seven weeks of radiotherapy and chemotherapy, to which he responded well and was cancer-free for nine months.
Two months ago, the shocking prognosis was made, and friends of the couple were spurred into action.
"This makes you really appreciate living in a small community," Mrs Falconer said.
Next month, Mr and Mrs Falconer will celebrate their 18th wedding anniversary - and plan to do so within their new home environment.
