A marble feature wall is the most common upgrade in Hong Kong homes, yet quotations vary widely. Stone variety, book-matching, thickness, dry-hanging versus wet fixing, lighting reveals and finishing all move the total. Here is the breakdown so you know where the money goes before ordering.

1) Stone, by variety and area; strongly veined varieties usually cost more. 2) Book-matching, which adds 10 to 20 percent wastage over random laying. 3) Thickness: 18 mm is standard for walls, thinner panels for light troughs. 4) Installation: dry-hanging costs more than wet fixing but allows maintenance and suits large formats. 5) Finishing: light troughs, internal and external corners, skirting and cut-outs. 6) Transport and handling.
1) Whether to book-match: the best effect but more wastage and labour. 2) Variety: popular whites such as Calacatta and Carrara have stable supply and transparent pricing, while rare luxury stone can cost several times more. 3) Dry-hanging versus wet fixing: wet fixing is cheaper but hard to maintain later; dry-hanging costs more but is demountable and suits large panels.
Feature walls are usually modest in area, for example 3 m by 2.5 m, so choosing a strongly veined variety lifts the result without greatly increasing total cost. Use offcuts for window sills and thresholds, and specify thinner panels for light troughs to save material and space.
Measure, select slabs, approve the dry lay, factory cutting, site installation, finishing, sealing, handover. At handover check that the book-match aligns, joints follow the veining, gloss is consistent, junctions are flush and the light trough glows evenly.
Depending on variety, area, book-matching and fixing method, anywhere from around ten thousand to tens of thousands of dollars. Send wall dimensions and preferred varieties for an itemised quote.
Not required, but the effect differs greatly. On a tight budget, vein matching or a single large panel with consistent vein direction already looks good.
Wet fixing is cheaper and suits small areas; dry-hanging costs more but is demountable and suits large formats and concealed light troughs. The choice depends on wall structure and design.
