Office Renovation Budget: Build a Scope-Based Cost Breakdown

An office renovation budget should show what the business is buying and what remains uncertain. Break the project into measurable packages before comparing totals or setting aside the final contingency.

Separate project costs

Distinguish design, construction, specialist services, furniture, technology and relocation. Identify taxes and landlord-related costs where applicable. A construction quote may cover only one part of the business's overall commitment.

Establish the retained baseline

List existing partitions, services, furniture and finishes that may remain. Have the relevant parties assess suitability. Reuse should be a documented decision, not an assumption that all existing items need no further work.

Break down the construction scope

Compare removal, protection, partitions, ceilings, flooring, joinery and services as relevant. Use consistent quantities and material assumptions. This makes optional upgrades and missing items easier to identify.

Track provisional allowances

Record the basis for unconfirmed products, quantities or existing conditions. Ask how each allowance becomes a final price. Keep a separate record of risks that cannot be resolved before site assessment or opening-up work.

Control the budget during design

Request cost implications before approving changes. Compare alternatives on the same functional brief and update the forecast with approved variations. Do not treat the original tender total as the current project cost after the scope changes.

Example enquiry to adapt

Please separate the office project's design, construction, specialist services, furniture, technology and relocation costs. Show retained items and provisional allowances. Provide a scope-based construction breakdown and identify the decisions that could change the forecast.

Prepare a comparable enquiry

Share the premises type, floor plan, operating needs and target timing with shortlisted firms. Browse renovation company directory and request proposals against the same requirements. The related guides and company information below provide further reading for planning the next stage.

Frequently asked question

Is a cost-per-square-foot estimate enough to approve a budget?

It can support an early discussion, but the actual condition, services, specification and project costs need a scope-based review.
