Grandview Garden — Buying, Surveying and Renovating a Second-Hand Flat
Four Hong Kong estates share this name, built between 1985 and 1999. This case study covers what to check before you buy, how the survey becomes a budget, and how payments and supervision should be structured. See the viewing checklist, identify the estate, or request a quotation.
Interior design project by D-8 Limited at Grandview Garden, Hong Kong.
D-8 Limited is an integrated design firm on interior design. It emphasizes on details in its design philosophy, which could be reflected on both the user experience and form of its works. As an evolving design studio, it offers animation visualization as an advanced presentation tool for their client to easily understand the design and outcome in a more comprehensive way.
Most renovation disputes begin before a contract is signed — at the moment a buyer assumes a flat needs a refresh when it actually needs rewiring. Detailed documentation and clear communication start at the survey, not at the drawing. Because we design and build, the party writing the number is the party who will be held to it, which is why we would rather find a problem at a viewing than during demolition.
Four Hong Kong Estates Called Grandview Garden
Establish which one before anything else — the age gap between them is fourteen years, and the scale gap is fifteenfold.
18 Bridges Street, Sheung Wan — 1994
Two 25-storey blocks with three units per floor, 150 units, developer Yu Tai Hing, occupation from March 1994, saleable areas 376 to 395 square feet, primary school net 11, in the Central and Western District off Hollywood Road. Implication: compact units in a small building on a steep street — access planning matters as much as the flat.
8 Nam Long Shan Road, Wong Chuk Hang — 1985
Two blocks, 294 units, developer Sun Hung Kai, occupation from 21 March 1985, saleable areas 294 to 565 square feet, primary school net 18, in the Southern District near Wong Chuk Hang station. Implication: the oldest of the four — assume full infrastructure renewal and check the statutory inspection position.
71 Pau Chung Street, To Kwa Wan — 1993
Four blocks, 512 units, developer K. Wah, occupation from 26 March 1993, saleable areas 354 to 645 square feet, primary school net 34, in the Kowloon City District. Implication: the widest unit range of the four, so the flat letter matters more than the estate name.
185 Hammer Hill Road, Diamond Hill — 1999
Grand View Garden, a Home Ownership Scheme estate in the Fu Shan area of Wong Tai Sin District, six blocks and 2,230 units, occupation from 18 November 1999, saleable areas 467 to 584 square feet, primary school net 45. Implication: the youngest and by far the largest — formal estate management, competitive lift bookings, and a smaller infrastructure share of the budget.

What to Inspect Before You Buy
A viewing is usually spent looking at rooms. Twenty minutes spent looking at services instead will tell you more about your renovation budget than the entire floor plan. Seven steps.
- Establish the occupation permit date and estate scale. Building age predicts renovation scope more reliably than anything a seller says. Note the year, the number of blocks and units, whether there is a service lift, and whether statutory inspection schemes apply.
- Open the electrical distribution board. Count the circuits, look for residual current protection, judge whether it looks original. An original board almost always means rewiring — the largest invisible cost in any renovation.
- Run water and watch it leave. Every tap and shower together for several minutes, every WC flushed. Watch for pooling, listen for gurgling, and look under every sink for staining or temporary repairs. Slow drainage is a stack problem, and new tiles do not fix it.
- Look for the four signs of moisture. Rust-coloured staining, straight hairline cracks along a reinforcement line, a hollow sound when tapped, and bulging or flaking paint in a defined patch. Any of them on a ceiling, beam or external wall points to spalling — regulated repair work, covered on our Spalling Repairing Works page.
- Test the windows and look beneath the sills. Open and close every window, check sealant condition and hinge corrosion, and examine the wall below each one for staining. Aged sealant is a recurring source of damp in the wall beneath.
- Photograph and measure. Every room from two corners, the distribution board, under every sink, and any suspect area. Measure the longest wall in each room so a designer can sanity-check the plan against reality — sales plans simplify geometry.
- Ask the management office three questions. Has a Mandatory Building Inspection Scheme notice been served? Is a prescribed repair programme scheduled? Are there known common-parts drainage or external wall defects on this floor? Each answer moves both budget and timing.
We attend viewings for clients who are still deciding. Twenty minutes on site before you commit is worth more than any amount of negotiation afterwards.
What a Cosmetic Refresh Looks Like
Many second-hand flats are painted before sale. That is normal and not sinister — but it is worth being able to tell a refresh from a repair.
Signs of a quick pre-sale refresh
- Paint over silicone at bath and basin junctions — a repair would have replaced the silicone, not painted it
- Painted window hinges and handles, meaning the windows were not serviced, only coated
- Paint on floor edges and skirting tops, indicating speed rather than preparation
- One freshly painted ceiling in an otherwise consistent flat — ask what was above it
- Recent paint smell combined with a hollow sound when the surface is tapped
- Furniture or storage boxes against one wall only, which may be covering staining
- New silicone at a single window rather than throughout
What is genuinely reassuring instead
- A distribution board that is clearly not original, with labelled circuits and residual current protection
- Replacement drainage visible under sinks with clean, consistent connections
- Windows that operate smoothly with intact, flexible sealant
- Even floor levels at thresholds and no hollow sounds underfoot
- Documentation — an owner who kept certificates and a finishes schedule usually maintained the flat too
What none of this decides
Whether to buy. A flat needing full infrastructure renewal is not a bad flat; it is a flat with a known and quantifiable cost. The purpose of the survey is to make that cost visible before the price is agreed rather than after.
How the Findings Become a Number
Electrical, plumbing and wet trades typically take roughly 20 to 25 per cent of the construction budget, and custom joinery another 20 to 25 per cent. What the survey changes is where in those ranges you sit, and how large a contingency is prudent.
Three budget profiles
- Flat with renewed services — wiring, drainage and waterproofing already replaced by a previous owner. Infrastructure share at the lower end, more budget reaching visible work, smaller contingency.
- Flat with original services — rewiring, drainage replacement and waterproofing renewal all required. Infrastructure share at the upper end, and the sequence cannot be shortened.
- Flat with moisture or spalling — add structural repair by a prescribed registered contractor, plus curing and drying time before finishes. The area is confirmed only after hacking, so a marked provisional sum is essential.
Priority order when the budget is fixed
- Spalling or structural repair, where found
- Rewiring, drainage, waterproofing and levelling
- Bathroom and kitchen, which cannot be phased once started
- Primary bedroom wardrobe run and entrance storage
- Living room and secondary bedroom joinery
- Decorative work, lighting fittings, curtains and loose furniture
Quote on saleable area
Any per-square-foot figure must state whether it uses saleable or gross area, because using gross inflates every line. It is one of the checks in our 18-point quotation checklist, alongside the warning signs when comparing quotations.
How Payments Should Be Structured
Payment terms decide who carries risk during a renovation. The principles below apply regardless of who you engage.
Tie payments to inspected stages, not dates
A calendar-linked schedule pays for time; a stage-linked schedule pays for progress. Each stage should be defined in the contract — for example demolition and site protection complete, first fix electrical and plumbing complete and inspected, wet trades and waterproofing complete with the flood test recorded, joinery installed, and practical completion — so both parties know exactly what triggers a payment.
Keep the opening payment proportionate
A deposit funds mobilisation and initial material orders, and that is legitimate. A very large payment before any work has started is not, because it transfers all early risk to the owner. Ask what the deposit is actually funding, and expect a straight answer.
Retain a final portion until handover is complete
The last payment should fall due after snagging is rectified and the handover documents are issued — as-built drawings, finishes schedule, electrical Work Completion Certificate, flood test records and warranty terms. The full handover pack is described on our Flat C case study.
Price variations before they happen
Every change of scope should be priced and approved in writing before execution. Settling variations at the end, under time pressure and with the flat almost finished, is how relationships and budgets both break.
Mark provisional sums as provisional
In an older flat, some conditions cannot be seen before demolition. A provisional allowance with the applicable unit rate stated turns any increase into arithmetic. A quotation showing no provisional items in a 1980s or 1990s flat has either not surveyed properly or intends to raise the price later — the argument is set out in full on our older-building case study.
What Site Supervision Should Actually Deliver
"Project management" appears in every quotation. These are the five things it should mean in practice.
One named point of contact
Someone who knows the drawings and can answer without checking with three other people. In an integrated practice that person is inside the same company as the designer — which is the structural argument for design and build set out on our comparison section.
An agreed reporting rhythm with photographs
Weekly is normal for a residential flat, more frequent during critical stages. Photographs matter more than text, particularly for anything about to be concealed.
Hold points before anything is covered
Three matter most:
- First fix electrical and plumbing, before walls are closed — socket, switch and data positions checked against the furniture layout and joinery internals while they can still be moved
- Waterproofing flood test, before tiling — filled and held for roughly 24 to 48 hours with the result recorded, because a failed membrane found later means demolishing finished work
- Joinery site template, after wet trades and before fabrication — because cabinets are cut to the built dimension, not the drawn one
A written variation record
Running, dated and cumulative, so the client always knows the current contract sum rather than discovering it at the end.
Honest reporting of delay
Delays happen — a material arrives late, a lift slot is lost, demolition reveals something unexpected. Reporting them when they occur allows the programme to be adjusted. Reporting them at the end is not project management; it is an excuse with a date on it.
Layout Strategy, 294 to 645 sq ft
294 to 395 square feet
Capacity is the entire argument. One consolidated full-height storage wall; an entrance cabinet with ventilated shoe storage and a drop shelf; a decisive bed strategy — platform with drawers, or a fixed bed with a top box; and a kitchen switched to drawer stacks. Keep the longest diagonal from the entrance clear and use sliding doors where clearance is tight. The compact planning method is on our Novum East case study.
430 to 520 square feet
Primary bedroom takes a full wardrobe run with stacked short-hang and a top box, plus a bedhead panel with reading light and charging that removes bedside tables. The second bedroom takes one decisive option depending on use, and a utility cabinet absorbs vacuum, drying rack and ironing board.
565 to 645 square feet
Storage stops competing with circulation. A third room can genuinely serve as study and guest room with a convertible desk or wall bed, and the living area supports a proper feature wall concealing router, set-top box and cabling with ventilated compartments.
Common to every size
Design storage from measured capacity rather than a nominal cabinet count — count hanging length, folded stacks, shoes and luggage first, using the method on our storage audit case study. And keep deep cabinets ventilated at the back, because in an older building the wall is the variable, not the cabinet.
Timeline From Completion of Sale
Realistic durations
Design, drawings and quotation commonly two to four weeks. Construction for a second-hand flat typically runs eight to fourteen weeks — demolition three to seven days, wet trades and waterproofing five to ten days, electrical and plumbing seven to fourteen days, joinery fourteen to twenty-one days, painting five to ten days, installation and cleaning five to seven days. Allow three to five months from taking keys to moving in.
Start design before you take keys
Layout options, storage audit and material direction can all progress from the floor plan and viewing photographs, so drawings are ready when access is. Final measurement still waits for possession, but the front half of the programme need not.
Renovate before moving in
An empty flat lets trades work in parallel, removes protection and furniture-shifting costs, and shortens the programme. Working around an occupied household is feasible room by room but costs more and takes longer — the method is on our Park Avenue case study.
Estate requirements
Works application with schedule, contractor insurance and refundable deposit; service lift booking, genuinely competitive in a 2,230-unit estate; protection of lift car, lobby and corridor; specified delivery routes; restricted hours for noisy operations; same-day debris removal. Where works fall under the Minor Works Control System, Class II submissions use Form MW03 as the notice of commencement and Form MW04 as the certificate of completion — see the compliance section.
