Please plot the psf trend for every 5 storeys in Parc Clematis for the years 2019 and 2025, and state the percentage increase in average psf for each floor range from 2019 to 2025.

I appreciate your interest in Parc Clematis pricing data, but unfortunately the search results provided do not contain sufficient granular information to accurately plot price per square foot trends broken down by specific floor ranges (every 5 storeys) for the years 2019 and 2025.

The available data shows:

- Overall project average prices from 2019 launch at approximately $1,580 psf
- Current 2025 resale prices averaging around $2,132 psf
- General price appreciation of approximately 35% from launch to 2025

However, the search results do not provide floor-level-specific pricing data that would allow me to segment the analysis by storeys (such as floors 1-5, 6-10, 11-15, etc.) for comparison between 2019 and 2025.

To obtain this detailed floor-by-floor price analysis, I recommend contacting EdgeProp Singapore directly or reaching out to the developer's sales team, as they would have access to comprehensive historical transaction data segmented by specific floor levels across the different years you're interested in analyzing.
