By understanding these cost drivers, you can make better decisions and avoid overspending.

Older buildings often need additional repairs or upgrades to meet current safety and compliance requirements.Building regulations and compliance
Your office must meet local health and safety regulations. Compliance work adds to your budget.Project timeline
Fast-tracked projects can cost more due to overtime or increased labour costs.

Removing old fittings, flooring, ceilings, partitions, and services is often the first step.
This also includes safe disposal of materials and site preparation.

Lightweight drywall partitions are cheaper than brick or glass walls.
