Pre-Construction

We’re able to take you from a conceptual stage to be in a position ready for building by going through the Planning, Building Regulations and Structural Engineering elements of work.

Quotation

Once all design drawings are complete and the scope of works have been defined, we provide a clear breakdown of costs along with a payment schedule and project programme with key milestones. We give clients the opportunity to negotiate and tailor the quotation to their budgets. Upon agreement, we will sign a written contract and establish a start date for works.

The Build

A site manager will be present on site daily ensuring a safe worksite and ensuring work is undertaken at the highest quality. We only sub-contract for specialist activities and endeavour to undertake all works in-house. We will set up means of communicating with our clients (WhatsApp groups, emails, weekly reports etc.) with regular site meetings planned to review progress. Towards the end of the project, we ensure your satisfaction by undertaking snagging inspections until your desired outcome is met.

Completion

We allow a retention payment to be kept by our clients for an agreed defect period (usually three months). All warranties and guarantees are provided.

"Great end to end service provided during my project, the team are very responsive and also helpful in helping unravel the tricky processes of architectural planning, seeking planning permission and working with third parties. Great working with you, and thank you for making the process smooth and transparent."
Mahir
★★★★★
"A reliable company providing sound advice needed for the work that needs to be done. There are many contractors out there, however, the benefit is having a structural engineer on board that can guide a project into being the best it can be. Working with budget helped us have peace of mind."
