Our expertise in office, creative space, and TI projects across San Diego and Southern California positions us to deliver results that increase property value and tenant satisfaction.
When building owners or property managers consider updating or repurposing office space, it’s important to understand the distinction between a TI and an office conversion. Each approach has unique benefits and can provide financial upside for property owners.
- Tenant Improvement – This encompasses updating or customizing an office space to meet tenant requirements. Depending on the project, it may consist of: layout changes, finishes, lighting, HVAC, and technology. If you’re looking for a cost-effective way to modernize a space and attract tenants quickly, this may be the way to go.
- Office Conversion – This involves transforming an existing office space into a new function or modernized layout. It unlocks underused areas, improves efficiency, and increases long-term property value. Larger in scope than TIs, office conversions can deliver significant ROI by attracting higher-paying tenants and enhancing asset performance.
The Wall – San Diego
A standout example of adaptive design, our work at The Wall showcases how we can reimagine and reconfigure an office space into a modern, functional environment that enhances the tenant experience while adding value for the owner.
