A refurb should keep avoidable disruption to a minimum, even when temporary shutdowns are necessary. The real test is whether teams can keep doing their jobs as far as possible while walls, wiring, air systems and lighting change around them. That takes a clear brief, the right permissions, thorough surveys and a phased plan that accounts for noise and downtime.

Agree the brief on evidence, not guesswork

Start with how the space is used right now. Pull pass data and desk-booking reports, then walk the floors at different hours to check what the data misses.

Turn that evidence into a short written brief that names headcount, team adjacencies, meeting needs and IT demands. Appoint a single brief owner on the business side who can make decisions and sign off the document. Getting that sign-off before designers draw helps reduce disputes about what the project includes. It also stops the scope drifting between a basic shell and a finished workspace with partitions, finishes, furniture and branding.

Don’t refurbish empty desks to the same standard as hard-working areas. If sensors show a zone sits unused for days, question whether it needs the same spend. You could shrink it or leave it out of this phase. Those decisions save capital while reducing the area contractors must work in. Keep the reasoning on file so no one reopens the debate mid-build.

Get the brief signed off before design starts.

Give the brief owner authority to make decisions. They should control changes, attend site meetings and approve costs against the brief.

Write down what success looks like for staff as well as for the building. Less queueing for meeting rooms and faster log-in in any zone are useful results to measure. Use those tests later when you tune the space.

Protect the lease position and get permissions in order

Read the lease before you set a budget. It will state when you need formal landlord consent for alterations and what you must hand back at the end of the term.

Apply for any required landlord consent early and allow time for questions. Landlords often ask for drawings, method statements, proof of insurance and programme dates before they sign. Assess the relevant building approvals with your advisers, including requirements affecting fire safety, access, ventilation and escape routes. Line up who provides each document and who chases the sign-off. Don’t start stripping out until the necessary permissions are in writing.

Check the end-of-term repair duties with your adviser. A refurb can trigger claims if you remove or alter landlord fixtures without agreement. Photograph conditions and log agreed finishes. That file helps protect your position when the lease ends.

Name who handles lease matters. It is often the office manager with support from a legal adviser and a surveyor. They should report consent status at each project meeting. Unresolved consent queries can quietly delay the schedule.

Previous work in the building does not settle the consent position for your project. Don’t assume a past fit-out means past consent covers new works. Check the proposed alterations against the lease and keep the relevant correspondence together.

Keep landlord contacts close to hand during the works. Quick answers can stop small queries becoming stop notices.

Understand the building and set up safety duties

Commission the relevant surveys before design freezes, with advice on their scope. Structure, services, drainage and asbestos information all shape what you can keep and what you must replace.

Mechanical and electrical systems can bring substantial hidden costs. Risers, comms rooms, power intakes and air systems may look fine until you open them up. Get an engineer to assess loads, trace cabling, check ventilation rates and record spare capacity. Ask whether a drainage check is needed too, as blocked or broken runs can flood a new finish. Share every report with the design team so layouts respect limits.

Don’t disturb fabric until a competent asbestos surveyor has scoped the work. A management survey covers normal occupation; a refurbishment or demolition survey identifies hidden asbestos-containing materials before intrusive work. Its scope must cover the affected area, which must be vacated for destructive surveying and assessed as fit for reoccupation afterwards. Allow time for analysis and controlled removal where needed rather than risking an uncontrolled site stop.

As the client you retain specific health and safety duties. You must appoint competent people for each role and allow enough time and resources for safe delivery. You must share pre-construction information with the full team. Where more than one contractor is involved, appoint a principal designer and principal contractor; every project needs a construction phase plan before construction starts.

Keep these records where site managers can find them. Missing paperwork is a common cause of delay.

Choose a delivery route you can manage

Refurbs take time from every side of a business. Drawings, landlord queries, permits and site decisions can swamp a small in-house team. Many businesses partner with a specialist that handles office refurbishments end-to-end, from early feasibility through to handover, because the coordination load is too high for a lean in-house team to carry alone.

Using one team for design and construction gives you a single point of accountability. If a detail clashes with site conditions, you have a clear first contact. That can simplify coordination, though responsibilities and dispute procedures still need to be clear in the contract.

Agree a realistic schedule that allows for approvals, lead times, testing and training. Hold a separate ring-fenced contingency for latent conditions and late changes, sized with your cost adviser for the risk you carry. Don’t spend it on upgrades early. Keep a phased commissioning slot after handover for snagging and tuning.

Develop the services plan before you procure the builder. Comms room upgrades, riser cabling, power distribution and cooling should be drawn and priced early. Finding these works late can mean substantial outages and changes to the programme. An agreed services design gives you a firmer basis for managing cost and time.

Put decision dates in the contract. Late choices on finishes or IT push work into the wrong sequence and can cost more than the item itself. Keep those deadlines visible.

Phase the works and plan every move

Split the floor into suitably separated zones and refurbish them in sequence. Contractors work inside hoarded areas with their own access while teams use retained zones with agreed routes.

Put the loudest and dustiest tasks outside core hours where the building allows it. Even then, plan for some spillover of noise and smell. Don’t promise staff silence in retained zones. Set expected noisy windows in writing and keep to them. Agree barriers, dust controls and any negative air arrangements with specialists for the particular work and occupied areas.

Publish a clear move plan well before works start. It should state who sits where during each phase and which entrances, lifts, kitchens and toilets stay open. Include swing space in retained zones and agreed home-working cover for peak weeks. Update the plan weekly and remove old versions from circulation.

Plan IT moves with the same care. Schedule comms cutovers with rollback steps and test phones and log-ins before teams arrive. Keep a printed contact sheet for outage reporting. Agree fallback arrangements with IT specialists, including suitable spare equipment or backup connectivity where the risks justify them.

Tie the phasing plan into your business continuity routines. Agree delivery times, lift use, waste routes and utility shutdowns with building management. Brief reception on diversions for visitors. Test the plan once before heavy works begin.

Keep walkways lit and signed. Clear routes help visitors find their way without interrupting staff or entering work areas.

Run the live site with tight controls and communication

Live refurbishments depend on clear communication. Tell staff what will happen and where to go with problems.

Name a single site contact and publish their number. Send a short weekly note with dates, noisy windows, closed areas and contact details. Hold business briefings with team leads before disruptive tasks, alongside the contractors’ own toolbox talks. Log every complaint, acknowledge it promptly and give a realistic response time. Staff cope better with inconvenience when they feel heard.

Agree escalation steps for dust, noise, access blocks and utility faults. The site manager should have authority to pause non-critical tasks when thresholds are passed. Maintain essential fire safety, ventilation and lighting arrangements, with any temporary changes properly planned. Coordinate deliveries outside peak arrival times and reserve lift slots for materials.

Keep your business continuity sheet current. It should show temporary access routes, agreed lift use, delivery windows and backup power arrangements. Review it each Monday with facilities and security. Small adjustments can prevent larger problems later.

Don’t let rumour fill gaps in the plan. If dates move, say so early and give the new window. Honest, frequent updates help staff understand what has changed and how it affects them. Short, plain messages work best.

There’s always pressure to speed up once teams tire of hoarding and detours. Hold the sequence unless safety and quality allow a change.

Commission, hand over and tune after re-occupation

Don’t treat handover day as the finish. Plan a phased commissioning period for testing, snagging, tuning and training while teams return in waves.

Bring groups back in planned waves rather than all at once. Test every workstation for power, data, log-in and print before its owner arrives. Have competent specialists check air flow and temperature at desk level, not just on the plant display. Walk each zone with facilities to list snags with photos and owners. Close snags in priority order and report progress openly.

Hold a structured review after 30 to 60 days in the space. Ask about thermal comfort, ventilation, noise levels and IT reliability in each zone. Use the same questions for every team so results compare cleanly. This helps reveal patterns, from cold corners to booked rooms that sit empty.

Assign owners for each fix with dates. Have qualified specialists assess adjustments to set points and damper positions, alongside practical changes to screen layouts and desk allocations. Re-test after changes and tell staff what moved. Following through on early complaints helps build trust.

Collect manuals, warranties, as-built drawings and test certificates before the contractor leaves. Store them where facilities can reach them in seconds. Clear records give future teams a better starting point for maintenance and alterations.

Agree any defects retention or fund through the contract rather than withholding payment unilaterally. It should support completion of outstanding items on the agreed terms.

A live refurb tests planning as much as taste. Get the brief, permissions, phasing and handover steps signed off with clear owners. Teams will tolerate some dust when dates hold and messages stay clear. Leave the building tuned and ready for steady work.
