Knockdown Rebuild: A Planning Timeline

Alex Snaith5 March 202614 min read

The interactive timeline below is a fictional static planning example. Its dates, durations, status, notes, and sequence are not a record of a live build or a prediction for your project.

The build

The example assumes a 252-square-metre, two-storey knockdown rebuild. Those assumptions are included to demonstrate a planning structure, not to establish a normal duration or required sequence.

Adapt each phase to your approved documents, procurement method, trade scopes, inspections, site conditions, authority lead times, and advice from the people responsible for your build.

Why this matters: A single completion date hides dependencies and uncertainty. Break the project into useful stages, record the basis for each duration, and keep the plan current as real approvals, quotes, bookings, and site information arrive.

Illustrative timeline: planned vs fictional tracked duration

Tap each phase to explore static example steps and durations. They are neither comprehensive nor current evidence; confirm sequence and hold points with your certifier, consultants, and trades.

Fictional static example only. Durations, status labels, topics, and notes are not live project data, current market evidence, or an official programme. Build and verify a project-specific schedule with the responsible parties.
Design and document coordinationConfirm
Record the current document set, consultants, dependencies, review cycles, and issue status.
Site investigationsConfirm
Ask the responsible professionals which surveys, reports, tests, and follow-up work apply.
Approval pathwayConfirm
Obtain the current application, information, assessment, notice, and decision process from the relevant authority.
Owner-builder and insurance pathwayConfirm
Verify current eligibility, training, appointments, policies, statutory schemes, and records with official sources and advisers.

Expectation vs reality

This comparison demonstrates how a plan can include uncertainty. It is not a surveyed benchmark or a statement of what actually happens on owner-builder projects.

Fictional comparison
Example planned and extended scenarios
PhaseExample planExample extensionVariables to investigate
Planning & approvalsExample: 12 weeksExample: 16 weeksPossible variables: information requests, redesign, consultant availability, notice, and authority process.
Demolition & site preparationExample: 4 weeksExample: 6 weeksPossible variables: surveys, hazardous materials, services, access, disposal, approvals, and handover condition.
Structure & enclosureExample: 14 weeksExample: 17 weeksPossible variables: design changes, fabrication, access, inspections, weather, curing, delivery, and trade interfaces.
Services & finishesExample: 18 weeksExample: 24 weeksPossible variables: selections, shop drawings, manufacture, coordination, evidence, defects, access, and rework.
Completion & occupation pathwayExample: 6 weeksExample: 9 weeksPossible variables: testing, rectification, certificates, service approvals, inspections, and document acceptance.
The numbers are fictional arithmetic examples, not surveyed durations or a prediction. Obtain current project-specific programmes and update the record as evidence changes.

Delay risks to investigate

The big delays aren't the dramatic ones. They're the boring, bureaucratic ones that eat weeks without you even noticing:

Weather
Weather can affect safe work, material requirements, access, curing, and trade bookings. Build activity-specific allowances with the responsible professionals.
Trade availability
A delay can affect later bookings. Confirm lead times and availability directly, record booking assumptions, and keep alternatives under review.
Inspection rebooking
Failed or rescheduled inspections can affect downstream work. Confirm notice periods, prerequisites, and rebooking arrangements with your certifier.
Service connection lead times
Each relevant service provider has its own application, design, payment, construction, and connection process. Confirm current lead times for the property.
Late selections
Some selections affect documentation, ordering, or later work. Identify decision owners and required-by dates, confirm lead times with suppliers and trades, and record how changes are handled.

What I'd tell someone about to start a KDR

If you're reading this before you've broken ground, here's what I wish I'd known:

1
Document the uncertainty in each duration and set risk allowances from project-specific evidence rather than a universal percentage.
2
Ask trades for current lead times and booking conditions, then update dependencies when dates change.
3
Confirm service-connection processes and prerequisites early with each relevant provider.
4
Link selections and approvals to the activities that need them, and confirm supplier lead times before setting deadlines.
5
Keep a running list of every certificate you need. Start collecting them from the first trade. Chasing paperwork at the end is miserable and delays your OC.
6
Accept that you will lose time. Rain, inspection failures, trade no-shows or material delays will get in the way. Build buffer into your plan and your budget so it doesn't break you when it does.

Use this as a worksheet, not a promise
