What We Mean by “Architecture” for Real Projects
Architecture is where ideas become buildable, approvable designs. It’s not only about how a building looks — it is also about space planning, light, access, buildability, regulations and clear information for contractors.
Many delays and cost overruns happen when drawings are unclear or the design has not been developed enough before construction. Our focus is to deliver drawings that communicate the intent clearly and reduce surprises on site.
Our Architectural Services
Planning Drawings
Clear, well-presented drawings for planning applications, prepared to suit typical UK council requirements.
- Existing and proposed floor plans
- Elevations and sections
- Site/Block plan coordination (as required)
- Design updates and revisions
Building Regulations Plans
Detailed drawing packages suitable for Building Control submission and construction coordination.
- Construction build-ups (typical details)
- Key dimensions and notes
- Coordination with structural design
- Builder-friendly drawing sets
Measured Surveys (Where Required)
Accurate base drawings are essential. We can produce measured survey drawings from site measurements provided by you/your surveyor, or coordinate survey information into clean CAD plans.
- Existing plans/elevations
- CAD-ready base models
- As-built updates
Note: Site survey arrangements can vary depending on location and project needs.
3D Visuals & Rendering
High-quality 3D views help you visualise the design early, align stakeholders, and reduce late changes.
- 3D massing and concept views
- External renders (for presentation)
- Internal layout visuals (as required)
- Design option comparisons
Extensions, Loft Conversions & Internal Alterations
Architectural design and drawings for common residential projects, aligned with buildability and approvals.
- Rear/side extensions
- Loft conversions and dormers

Design Coordination (Architecture + Engineering)
Because Xponexus also delivers structural and civil engineering, we can coordinate the design holistically and reduce clashes between disciplines.
- Structural openings and beam coordination
- Drainage routes and levels coordination
- Practical detailing for construction
