About Our Process

1.

Initial Enquiry

We begin with an introductory phone conversation to understand your project, aspirations, budget expectations and timelines. For suitable projects, we then arrange an initial consultation either remotely or on site to review feasibility, discuss the overall vision and assess whether we are the right fit for one another.

2.

Project Development & Estimate

Once projects move beyond the initial consultation stage, we begin developing the project in greater detail. This may include feasibility discussions, budgeting, buildability reviews, design coordination and estimate preparation. Depending on project complexity, detailed consultations and estimate preparation may be subject to a fee, which may later be credited against the contract value upon appointment.

3.

Construction Phase

Once the scope of works, programme and agreements are finalised, construction begins. Through careful coordination, regular communication and structured project management, we guide the project from start to completion with clarity and attention to detail.

4.

Completion & Aftercare

Upon completion, we carry out a final walkthrough to ensure all agreed works have been completed to the expected standard. We also remain available for aftercare support and any post-completion guidance required following handover.

Common questions before getting started

1. Can you provide a quote without drawings?

We usually work from drawings or a reasonably clear brief. Where these are not yet available, our preferred Design & Build approach allows us to guide projects through an early pre-construction stage to help define the scope, budget expectations and overall build approach before moving into detailed estimating.

2. What budget should I expect?

Costs vary depending on scope, structural requirements, materials and level of finish, although most of our projects typically begin from around £100k.

We’re always happy to discuss realistic options that align with your goals, budget expectations and the overall complexity of the project.

3. When could you start?

Once we understand your project, we’ll advise on the most appropriate route forward — whether that involves progressing through our Design & Build pre-construction stage or working from an existing design package.

We can then arrange an initial consultation to discuss the project, overall feasibility and the next steps in more detail.

4. Do you work on competitive tenders?

We generally find the best project outcomes come from early collaboration, realistic planning and clear communication rather than heavily price-led tendering.

While we may consider selected tender opportunities, our Design & Build approach is typically best suited to projects where early contractor involvement and collaborative project development are valued from the outset.

5. What are the next steps?

Once we understand your project, we’ll advise on the most appropriate route forward — whether that’s progressing into pre-construction or working from an existing design. We can arrange a call to discuss your plans in more detail.
