PROPOSED CHECKS — NO MEASURED RESULTS SUPPLIED
Date: __________________  Units: __________________
Room / product reference: __________________

1. Actual passing conflict
Where: At the exposed kitchen end while another user occupies the sink and appliance doors are open.
Record: Mark the traveled route, obstruction positions and alternative outlines with dimensions in centimeters.
Your observation: ______________________________________________
Interpretation: A local curve helps only a local conflict; persistent restriction points to an oversized footprint.
Alternative: Reduce or relocate the cabinet before refining the radius.

2. Top and base relationship
Where: In plan and section through the rounded countertop, support, end panel and nearest handle.
Record: Record projections, support details and whether any square base remains in the passing route.
Your observation: ______________________________________________
Interpretation: Rounding the top does not remove a cabinet or handle obstruction beneath it.
Alternative: Coordinate the whole end or use a simpler chamfered or straight arrangement.

3. Curved door value
Where: Inside the proposed shaped cabinet with its actual contents and front shown fully open.
Record: Measure clear opening and usable depths in millimeters; note hardware and replacement access.
Your observation: ______________________________________________
Interpretation: A functioning curved front may lose capacity without improving access enough to justify its complexity.
Alternative: Use a fixed shaped end panel and locate active storage in straightforward compartments.

PRACTICAL TRIAL
1. Compare square, chamfered and rounded outlines using stable safe mockups without operating hazardous equipment around them.
2. Ask regular users to follow their natural route without coaching, including carrying ordinary meal items.
3. Inspect an edge sample and obtain a complete fabrication, support, cleaning and repair description before approval.

COMPARE THE SAME SCOPE
- Complete end footprint including handles
- Occupied appliance and drawer positions
- Usable shaped cabinet capacity
- Countertop support and edge detail
Cost drivers: Curved door fabrication and hardware; Shaped countertop production; Custom end panels and repair parts
Choose another route when: A rounded detail should not be used to excuse inadequate overall circulation or a layout that fails with appliances open.

EVIDENCE BOUNDARY
This is a movement and construction-coordination plan, not proof of impact protection, structural support or universally suitable circulation.

DECISION CONDITIONS
choose: Choose a rounded end when the occupied route identifies a specific corner conflict and the revised complete cabinet-and-top outline improves it without weakening useful storage or required appliance access.
alternative: Reduce or relocate the island when the restriction continues along its full length; refining a radius is not an alternative to correcting an oversized plan.
stop: Stop fabrication when the exact top material's edge, support, seam or cutout requirements remain unresolved, even if the drawn curve appears gentle.

Corian Endura's design bulletin coordinates porcelain edges, cutouts, seams and support and notes the vulnerability of sharp edges. It supports resolving the selected worktop's fabrication separately from a circulation sketch; it does not supply a universal rounded-corner radius or guarantee collision prevention.
Scope: Exact Endura porcelain thicknesses and bulletin conditions apply; another worktop needs its own fabricator-approved design and support specification.
