Our Renovation Process

A renovation process built around decisions, deliverables and written control—not a four-step marketing promise. You see what happens next, what must be decided, and what should be in writing before construction begins.

What good process removes

Uncertainty is managed before it becomes site cost.

High-value renovation carries real variables: existing structure, hidden services, heritage fabric, planning policy, lease restrictions, neighbour procedures, access and long-lead finishes. The purpose of pre-construction is not to pretend those variables do not exist. It is to find, allocate and price as many of them as the project reasonably allows.

That means the design must become sufficiently technical before the construction price is treated as fixed. It also means client selections, provisional allowances and excluded work are visible. A short quotation cannot substitute for coordinated drawings, a specification and a contract.

The key decision gate

Do not move from concept to construction simply because the layout looks right. Move when the agreed design, approvals route, structural intent, specification, contract scope, programme and commercial assumptions are aligned.

The full route

Eight stages, with a decision at each.

Not every project needs every consent or consultant. The sequence is adapted after the property and brief are understood.

01

Initial conversation & brief

We establish the property, desired outcome, ownership position, likely scope, budget parameters and any dates that genuinely matter. If the project is not a fit, that should become clear early.

Decision / output

A written summary of the brief and the recommended next investigation or appointment.

02

Survey, constraints & feasibility

The team reviews existing fabric, structure, services, access, planning or heritage context and—where relevant—leasehold and neighbour constraints. Specialist surveys are identified rather than silently assumed.

Decision / output

Measured information, initial risk register, consent route and viable scope options.

03

Concept design & option testing

Layouts and interventions are tested against the brief, structure, daylight, circulation, heritage significance and budget. The aim is to select a coherent direction before detail multiplies.

Decision / output

Preferred concept, key client selections and authority to progress the chosen scheme.

04

Consents & technical coordination

Depending on the project, this can include planning, listed building consent, a lawful-development route, Building Control, structural design, party-wall procedure or a Licence to Alter. These are separate approvals with different decision-makers.

Decision / output

Required submissions and a coordinated technical package suitable for pricing and construction.

05

Scope, quotation & contract

The construction scope is assembled from drawings, specification and known site conditions. Inclusions, exclusions, allowances, client-supplied items, change procedure, programme basis and payment terms are made visible.

Decision / output

Agreed contract documents, contract sum or pricing basis, payment schedule and named responsibilities.

06

Pre-start & procurement

Before site opens, the team coordinates long-lead orders, access, protection, waste, working hours, temporary services, neighbours, inspections and the information still required from the client.

Decision / output

Pre-start meeting, construction programme, logistics plan and outstanding-information schedule.

07

Construction, reporting & change control

Work is sequenced against the programme, with inspections and client decisions recorded. Discoveries and requested changes are assessed for design, cost and time effects instead of being allowed to drift into the final account.

Decision / output

Progress record, decision log, written variations and updated programme where required.

08

Completion, handover & aftercare

Snagging, applicable inspections and commissioning are completed before the agreed handover. The client receives the documents scheduled for the project and a written route for raising post-completion items under the contract.

Decision / output

Practical-completion record, keys, applicable certificates and warranties, operating information and aftercare contacts.

Commercial clarity

Programme and payments should be project-specific—and written.

A listed townhouse, lateral apartment and rear extension cannot honestly share one website timeline or payment percentage. They can share a disciplined framework.

Why no universal payment percentages are shown here

The right structure depends on procurement, project duration, bespoke orders and the selected contract. We will show the actual schedule before you sign. That is more useful than publishing a percentage that may not apply to your project.

Responsibility map

One route does not mean anonymous roles.

The people and professional appointments vary by scope, but the responsibility split should be explicit before the relevant stage begins.

Before you appoint

Questions worth asking before site starts.

Before work starts

When can you give a fixed quotation?

A reliable fixed quotation follows enough survey, design and specification work to define the scope and expose the main constraints. Quoting before structure, consents, access and finishes are understood simply moves uncertainty into allowances or later variations.

How long will design and approvals take?

There is no responsible universal answer. A largely internal freehold refurbishment follows a different route from a listed property, basement, extension or leasehold apartment. We identify the likely approval path at feasibility stage and issue a project-specific pre-construction programme.

Will I know who is responsible for each stage?

Yes. Before the relevant work starts, the appointment or contract should identify the project lead, design and engineering responsibilities, any separate professional appointments, and the site contact. The named people depend on the agreed scope rather than a generic website team list.

Contract, changes and handover

How are stage payments arranged?

The contract sets the payment schedule for that project. Construction payments should be linked to defined stages or assessed progress, with due dates and the basis of valuation recorded before work starts. Any design fees, mobilisation payment, retention or final payment are stated expressly rather than assumed from a generic percentage.

What happens if the scope changes?

A proposed change is recorded with its effect on price, programme and related work before it is instructed wherever practicable. Urgent safety or opening-up discoveries may require a faster decision, but they should still be documented so the cost and programme record remains clear.

What should I receive at handover?

The handover schedule is project-specific. It may include the agreed snag record, Building Control completion documentation, electrical or gas certificates, product information, manufacturer warranties, operating information, keys and the written aftercare route. The contract should state what applies to your project.
