Choose your starting point

Which construction service do you need?

The right appointment depends on what is already in place. These are the most common starting points.

You have an architect and drawings

Traditional construction suits you if you already have an architect and drawings and want a builder to deliver them.

You need help with costs or a finished building

Cost consultancy helps with budgets, quotes and cost decisions. For a finished building, maintenance and aftercare covers repairs, small works and ongoing care.

For a useful first conversation, share the project location, the type of work, your current drawings or brief, and any target dates. If the budget or programme is still being developed, tell us that too.

A straightforward route

What happens after you get in touch

You don’t need a finished brief before you call. We start with what you know and work out what’s missing together.

Initial conversation

Your aims, current information and immediate concerns.

Review & site visit

We look at the site, its constraints and what is possible.

Scope & proposal

A defined route, responsibilities and commercial basis.

Plan & deliver

Coordinated people, information, cost and programme.
