What Influences the Cost of an Interior Design Project?
We do not publish fixed rates — every project is priced individually after a short conversation about the property. The cost of a comprehensive interior design project depends on several factors, all of which affect the volume and complexity of technical documentation required.
Design style and aesthetic complexity
This is the most significant pricing factor. The difference in documentation workload between a contemporary minimalist interior and a classical or art déco project is substantial. Modern, clean-lined styles involve extensive but more repetitive documentation. Classical styles — modern classic, art déco, glamour, old money — require individual technical drawings for every decorative element: each cornice profile, wall panel, transition detail and corner finish. The more precise and ornamental the style, the more documentation — and the higher the fee.
Floor area and scale of the investment
Larger properties spread the fixed cost of the project across more square metres, which generally lowers the per-metre rate. Smaller apartments and apartments require proportionally higher per-metre fees, as every room requires the same number of drawings regardless of total floor area.
Building geometry and structural complexity
A house with a simple, regular layout is significantly more efficient to document than a building with an elaborate attic, multiple pitched ceilings, irregular angles or non-standard arches. Every structural irregularity generates additional drawings and verification work.
Number and complexity of bathrooms
Bathrooms are among the most labour-intensive rooms in any project — each requires wall-by-wall tile layout drawings, plumbing schematics, custom furniture designs and lighting plans. A property with five non-standard bathrooms will be priced proportionally higher than one with two standard-layout bathrooms.
Scope of fixed joinery and bespoke furniture
Walk-in wardrobes, library walls, fitted kitchens, alcoves and custom-made furniture elements all require individual workshop drawings. The more bespoke joinery in a project, the more extensive — and the more precisely priced — the documentation package.
International or premium specification coordination
Projects where a significant portion of the furnishings and finishes comes from international suppliers, is produced to individual commission, or requires specialist coordination with manufacturers and contractors involve a meaningfully higher workload at the specification, technical verification and supervision stages. This scope is always discussed and agreed at the quotation stage.
