What Really Drives the Cost of Luxury Interior Design

What Really Drives the Cost of Luxury Interior Design

Luxury interior design is rarely about a single price per square foot. It is the sum of many decisions — materials, joinery, lighting, furniture and the level of detailing — and understanding them early makes budgeting far more predictable.

Scope matters most

A project that includes civil modifications, new electrical and plumbing, custom carpentry and full styling will cost very differently from one that is limited to soft furnishings and decoration. Be clear about what is included.

Materials and finishes

Natural stone, solid timber, handcrafted metalwork and bespoke upholstery cost more than laminates and standard fittings. The best strategy is to invest where you touch and see most — and economise where it does not show.

Detailing and craftsmanship

Flush joinery, concealed lighting and perfectly aligned junctions take skilled labour and careful supervision. That quality is a large part of what makes a space feel luxurious.

Planning for the budget

A good designer will help you set priorities, phase the work and avoid expensive changes midway through the project. Use our cost calculator for an indicative range, then speak to us about a detailed estimate.
