A clearly labelled concept study, from the existing building to an imagined finished space.
A visual design comparison
Before & after
Two illustrative views of the concept property. Generated details may vary; this is a design visualisation, not a record of actual construction.

Illustrative Case Study
Visualisations are provided to demonstrate a typical project and are not photographs of a completed client project. People are fictional and do not represent named employees or customers.
Project overview
This fictional edwardian brick house is used to explore rear extensions. The design brief imagines a homeowner seeking more useful living space while retaining the parts of the existing home that continue to serve it.
The design challenge
The proposal needs to connect the new layout with the existing structure. Survey information, load paths, openings and interfaces would need to be reviewed before selecting a project-specific structural scheme.
The approach illustrated
A good structural scheme starts with the way you want to live. We bring the proposed layout, the existing building and the construction sequence into the same conversation. The visual sequence follows an imagined survey, construction and finished condition. It does not establish that these works were designed, built or approved by structonix.
Structure
Structural engineering
The design would need to establish the existing support arrangement and the effect of the proposed alterations. Depending on the verified layout, the scope could include beams, bearings, connections, foundations, timber members or roof design.
No exact member sizes, loads, foundation depths or calculations are supplied in this illustrative study. A competent project-specific design is required before construction.
Drawings & engineering
No genuine project drawings or calculation extracts have been supplied. The photographs are not construction details or design documents.
Technical coordination
Building Regulations considerations
A real proposal would need a review of the requirements for its use, location and scope. Structure, fire safety, moisture, ventilation and thermal performance may need coordination, alongside drainage, access and electrical implications where relevant.
No planning decision, Building Control approval, inspection or completion certificate is claimed.
