How We Work

Our process follows the principles of the IStructE Plan of Work, adapted for residential projects so it remains clear, practical and easy to follow. Whether you’re removing a wall, converting a loft or building an extension, the same core steps apply — scaled to suit the size and complexity of your project.

Small Projects — Simple Process

For small projects, the structural process is straightforward:

  1. You send us an estate agent’s plan or a quick sketch.
  2. We send a clear, fixed‑scope fee.
  3. We prepare the structural drawings and calculations.
  4. You build — and we’re here if your builder has any questions.

This is the everyday workflow for wall removals, small alterations, simple beams, chimney removals and similar compact projects.

Larger Projects — IStructE‑Aligned Process

For extensions, loft conversions, refurbishments and multi‑room alterations, we follow a distilled version of the IStructE Plan of Work, adapted for residential projects.

Homebuyer Surveys & Structural Appraisals (Stage 1)

For many clients, the first step is understanding the condition and structural potential of a property — especially during a purchase. A structural appraisal or homebuyer survey provides early guidance on:

  • existing structural condition
  • previous alterations
  • load paths and constraints
  • feasibility of future works (extensions, lofts, wall removals)
  • risks that may affect cost or programme

This aligns with IStructE Stage 1 (Preparation & Brief) and forms the foundation for informed decision‑making before design begins.

Early Contact & Drawings Review (Stages 0–1)

You share your architect’s drawings or initial ideas, and we confirm what structural input is required.
For small projects, this may be as simple as reviewing a sketch or estate agent's plan.
For larger schemes, this aligns with the early feasibility stages of the IStructE framework.

Site Visit & Structural Strategy (Stages 2–3)

A site visit allows us to understand the existing structure, previous alterations, load paths, drainage routes, party wall conditions, any existing defects and any signs of movement. Where helpful, we advise on opening‑up works so the structural strategy is based on accurate information rather than assumptions.

This stage forms the core of the structural approach — identifying constraints early and shaping a practical, buildable solution.

Structural Design & Coordination (Stages 3–4)

We develop coordinated structural drawings, calculations and details that support the architectural layout and construction programme.

Most clients come to us once planning is approved and the project is ready for structural design. At this stage, the architect has usually paused their drawings at a natural point — we then flesh out the structural requirements so they can continue and complete the building regulations package with fully coordinated information.

Structural design is a two‑way process between architect and engineer, and both building control and the builder prefer receiving a coordinated set where the architectural and structural drawings align cleanly. Planning drawings aren’t intended to contain this level of detail; this coordinated package is what clients expect when they receive a full set of architectural and structural plans.

These drawings form part of the information used for building regulations approval and construction.

Construction Support & Completion (Stages 5–6)

During the build, we remain available for queries, clarifications or minor adjustments.
Once construction is complete, we assist with any final structural queries or documentation required by building control or your design team.
