Load Bearing Wall Assessment for Office Conversion

I'm exploring an office to flat conversion in Twickenham. Since the building is over a century old and I don't have access to its original plans, I need an expert to determine which walls are load bearing and which can be safely removed.

Key Requirements:
- Identify specific walls for removal: As I have some specific walls in mind that I would like to eliminate to create a more open space, it is crucial that the expert can confirm whether these are load bearing or not.
- Building Age: The building's age might make this a more complex task, hence the need for someone with experience in older properties.
- No access to original plans: Since I don't have access to the original architectural or structural plans, the freelancer will need to assess the building on-site.

Ideal Skills and Experience:
- Structural engineering or architecture background with experience in load bearing wall assessment
- Familiarity with older buildings, particularly those over a century old
- Able to carry out on-site assessment without reliance on original architectural plans

It is important that the freelancer can provide a comprehensive and reliable assessment to guide the office to flat conversion.
