Seamless Integration of Architecture & Engineering
One of OAS’s greatest strengths as a London Architectural Company is our unique ability to combine architectural creativity with structural practicality. Property owners frequently encounter the challenge of receiving attractive designs that prove unfeasible or prohibitively costly to construct. We mitigate this concern.
When creating measurements for loft conversions or developing documentation for comprehensive planning permission, our specialists guarantee adherence to construction codes and engineering specifications.
We assist customers throughout every digital phase. This assistance proves essential for individuals performing searches like London Architect download functions, where customers require immediate access to their electronic blueprints, PDF technical drawings, and three-dimensional models. Additionally, we manage the engineering details commonly known in professional terminology as London Architect BSS (Building Services & Structural) assistance, confirming that your utilities and structural elements are precisely engineered.
Core Services We Provide
- Residential Architecture: Loft conversions, rear extensions, and wrap-around extensions.
- Planning Permission: Handling lawful development certificates and full planning applications.
- Structural Engineering: Beam calculations and load-bearing wall removals.
- Commercial Projects: Change of use and office layouts.
The Modern Approach: The “Architects London Gig” Economy
The architectural industry is changing. The traditional model of expensive high-street firms is giving way to agile, online-first architectural services.
This shift is sometimes referred to as the Architects London gig economy, where flexible, highly skilled architectural designers work remotely to deliver results faster and more affordably than traditional firms. OAS embraces this modern structure. By reducing overheads associated with physical offices, we pass the savings directly to you without compromising on quality.
Therefore, whether you are a homeowner or a developer, you get the expertise of a top-tier London Architectural Company at a fraction of the usual cost.

Frequently Asked Questions (FAQs)
