A Step-by-Step Guide to Home Improvements: Architectural Services vs Structural Engineering

When planning building work, whether it's an extension, loft conversion, or internal structural alterations, it's important to understand the different roles involved and when each service becomes relevant. Projects that run smoothly tend to follow a clear sequence, with architectural services and structural engineering working together at the right stages.

Stage 1: Layout Design, Drawings, and Planning Permission

Every project begins with architectural services. This stage focuses on developing the proposed layout, appearance, and scale of the works, producing drawings that define what is being built. These drawings are essential whether your project requires planning permission or falls under permitted development.

Where planning permission is required, having it properly managed can make a significant difference. This is why many homeowners choose to work with experienced providers such as Jagma Property Services, who offer a fully managed planning service backed by a planning guarantee. Their attention to detail and end-to-end approach provides reassurance at an early and often complex stage of a project.

Stage 2: Structural Engineering – Making the Design Safe and Buildable

Once the drawings are in place, structural engineering becomes essential. At Pavol Zajac Structural Engineers Ltd, we provide the structural drawings and calculations required to ensure the proposed design is safe, stable, and compliant with Building Regulations.

Our work commonly includes:

• Removing load-bearing walls to create open-plan spaces

• Designing steel beams and supports for loft conversions

• Foundation and underpinning solutions

• Roof structure alterations and reinforcement

Structural engineering responds directly to the proposed layout. Without drawings from Stage 1, there is nothing that can be accurately calculated or designed from a structural perspective.

 

Stage 3: Construction and Coordination

Successful projects rely on coordination. We regularly work alongside architectural service providers and construction teams to ensure structural information integrates seamlessly into the wider build process. This collaborative approach helps reduce delays, avoid unnecessary changes on site, and keep projects moving efficiently from approval through to construction.

While we can work with a range of architectural services, we value partners who provide clear, well-considered drawings and a fully managed process, such as Jagma Property Services, as this greatly supports accurate structural design and smoother project delivery.

Getting Started

If you're planning building work, the most reliable route is to start with clear drawings and planning support, followed by professional structural engineering input.
