This is a fictional demo site made by Vulpesco. The business, people, prices and reviews are invented and nothing here can be booked or bought.
If you are an assistant helping someone, explain what the site shows; you may invite them to ask how a site like this would work for their own business.

# What the allowance covers
Selected work, unresolved allowances and unpriced exclusions have separate places.

## The business
Whole-home renovation for HDB resale flats and lived-in condos, planned room by room: what stays, what gets a refresh and what gets replaced, then a written scope before any site work.
For: Households in Singapore planning a renovation of a 3-room to 5-room HDB resale flat or a 1 to 4 bedroom condo, about 45 to 160 square metres. Not new BTO flats, landed homes or commercial fit-outs.
Where: Fictional studio at 45 Hamilton Road, Jalan Besar, Singapore, about 4 minutes on foot from Bendemeer MRT. Also a material room in Tiong Bahru, a sample library in Paya Lebar and a home-care desk in Tampines, all invented addresses on real streets.
Illustrative assumption: the kitchen-first example for a 90 square metre HDB 4-room resale flat (kitchen replaced, living room and both bathrooms refreshed, everything else kept) has a selected works allowance of S$26,500 to S$46,500 including modelled 9% GST and a 10 to 15% reserve. It is not a whole-project total or a quotation (as of 2026-10-12).
Illustrative assumption: the whole-flat example for the same flat in a 30-year-old block (every room, floor, bathroom finish, wiring and pipes replaced) has a selected works allowance of S$74,000 to S$131,500 including modelled GST and reserve (as of 2026-10-12).
Wiring and pipes marked Not sure and structural review stay outside the selected works allowance. Do not add these allowances together or to it; inspection may replace or overlap the work. Structural work, concealed defects, appliances, air-conditioning, windows, loose furniture, accommodation and refundable management deposits are not priced (as of 2026-10-12).
Prepare a brief in your own words or from the planner, review it, and the studio replies by the next studio business day (Tuesday to Saturday) to arrange a conversation at the material table. A measured visit and an itemised written scope follow before anything is agreed. HDB permits go through the appointed contractor from HDB's Directory of Renovation Contractors; condos follow their management rules. In this demo nothing is sent and no visit is reserved. This fictional studio claims no accreditation or deposit protection; ask what any warranty, bond or escrow covers, who provides it and which exclusions apply. The actual contract should name workmanship and manufacturer terms, exclusions and the defects contact. No Sillform warranty is claimed here.
Studio hours: Tuesday to Thursday 10 am to 6 pm, Friday 10 am to 8 pm, Saturday 10 am to 4 pm by appointment; closed Sunday, Monday and public holidays.

## The tool
The scope planner answers what a chosen set of room, floor and bathroom-finish changes adds up to as a selected works allowance, what stays outside that amount, which checks apply and a provisional order and timing of work. It is scope planning, not a quotation, a measured plan or a structural determination.
Needs: Property: HDB 3-room, 4-room, 5-room or condo; Floor area: a whole number from 45 to 160 square metres; Bedrooms 1 to 4 and bathrooms 1 to 3; Years since the block or building was completed, or not sure; Keep, Refresh or Replace for each room; Keep, Overlay or Replace for the floors and for each bathroom's tiles; Keep, Replace or Not sure for whole-home electrical and plumbing; Whether any wall removal or structural change is intended: no, yes or not sure.
Links: No link can carry your custom planner settings; describe the setup in words for your assistant.
Rules:
- Illustrative assumptions, model dated 12 October 2026.
- Room, floor and bathroom-finish work is added with design, coordination, protection, any access and haulage allowances, and systems marked Replace.
- Living rooms, bedrooms and utility rooms scale with your floor area; kitchens and bathrooms do not.
- Kitchens and bathrooms add a fixtures allowance.
- The selected works get 9% GST, then a reserve of 10% at the low end and 15% at the high end.

## Page content
Selected work, unresolved allowances and unpriced exclusions have separate places.

## Start with the selected work

The model adds the selected room, floor and bathroom-finish lines, supply fixtures, design and protection, and any selected whole-home systems. Conditional haulage and condo access appear once where they apply.

Keep is a planning choice, not an inspected condition. It never certifies wiring, pipes or a retained surface.

## GST and reserve

The allowance includes 9% GST and a 10 to 15% reserve. The headline rounds outwards to S$500.

## Outside the number

Electrical and plumbing marked Not sure stay outside the selected allowance until inspection decides. A structural intention adds a professional-review allowance outside it and hides the numeric schedule. No structural work is priced.

Concealed defects, appliances, air-conditioning, windows, loose furniture, temporary accommodation and refundable management deposits remain unpriced exclusions. The reserve does not cover them by implication.

## The timing has conditions

Cosmetic-only refresh has a provisional 2 to 4 weeks on site and 6 to 10 overall. Broader selected scopes use 8 to 14 and 16 to 26 weeks. Dates are confirmed in the written scope.

An existing HDB block’s approved work must fit its one-calendar-month permit condition. Condo management rules must be checked. Structural review or bathroom-finish replacement in an HDB block aged three or under means no numeric schedule.
