Many clients start a project by asking one simple question: “Who do I speak to first?” The answer depends on the type of work, the level of design required, and how much technical coordination the project needs.

When you need an architect first

An architect is usually the right first appointment where the project needs planning permission, a major layout redesign, a change of use, a new extension, or a design-led approach. They help define the spatial concept, planning strategy, drawings and overall look of the project.

However, an architect’s design still needs to be coordinated with structure, Building Control, fire requirements, services, cost and buildability. That is where early contractor or project-management input can save time and money.

When you need a contractor first

A contractor can be the right first call where the work is mainly refurbishment, repair, fit-out or improvement within an existing layout. Examples include kitchens, bathrooms, damp repairs, roofing, façade works, internal reconfiguration, small commercial fit-outs or property upgrade works.

The contractor should still be clear about what requires drawings, structural calculations, electrical certification, gas certification, Building Control approval or specialist input.

When a project manager adds value

A project manager is useful when there are several parties involved, the client is busy, the programme is tight, or the project has risk around cost, procurement, neighbours, access, structural works, M&E coordination or compliance. The project manager’s role is to protect the client’s brief and keep decisions organised.

The best route is often combined

For many London projects, the most effective route is not choosing one professional in isolation, but bringing design, technical advice and construction input together early. This reduces the risk of beautiful drawings that are difficult to build, or cheap construction plans that miss compliance requirements.

Typical early-stage sequence

• Define the brief, budget range and intended outcome.
• Check whether planning, landlord consent or Building Control approval is required.
• Prepare drawings or a written scope suitable for pricing.
• Obtain contractor input on buildability, programme and risks.
• Agree responsibilities before work starts.
