Understairs Planner

Plan fitted understairs storage, present ideas to clients and keep the project details together on your device.

Understairs Planner is a visual concept tool for homeowners, joiners and fitters. Enter the available space, compare storage layouts and finishes, then review the design in exterior, inside, measurement and realistic views.

PLAN AND PRESENT
- Straight and straight-with-landing stair configurations
- Guided measurements, reusable dimension presets and a photo reference
- Cupboards, drawers, pull-outs, shelves and other storage modules
- Door styles, materials, finishes and handles
- Offline realistic 3D view with rotation, lighting and image sharing
- Client presentation mode and side-by-side layout comparison

KEEP PROJECT DETAILS TOGETHER
- Local client records, staircase photos, notes and follow-up status
- Business branding and contact details for proposal PDFs
- Configurable business rates and indicative project estimates
- Optional client price display and proposal breakdown
- Saved projects, recovery drafts and editable backup import/export

REVIEW THE CONCEPT PLAN
- Cutting and fit settings, calculated parts and sheet layouts
- Parts grouped by unit, sheet or material
- Workshop order lists and printable part labels
- Locally generated PDFs for preview, printing and sharing
- Practical warnings for incomplete specifications and clearances

One-time paid download. No subscription, account, advertising or developer-operated cloud sync. Designs, client records and photos stay on your device unless you choose to export or share them. Public support and privacy pages open in your browser.

Calculated parts and prices are concept aids. Specify and verify materials, hardware, runners, fixings and installation details for the actual project. Purchased hardware is listed separately from sheet stock. Estimates depend on the rates and assumptions you enter.

Understairs Planner is not a verified survey, structural approval, manufacturing drawing or quotation. Verify site conditions, measurements, clearances, structure, services, materials, hardware and production details with a suitably qualified professional before manufacture or installation.
