Existing Buildings & Interior Alterations

New purpose for existing space.

Existing buildings come with constraints, but also with opportunity. Jahan Mehr Architects helps owners and tenants understand what can be retained, adapted or added, then develops a coordinated architectural response that addresses design, code, approvals and construction.

01

Begin with what is already there

Alteration projects require a reliable understanding of existing conditions. We review available records, document the space and identify the zoning, building-code, accessibility, fire-separation and servicing issues that may shape the project before the design is advanced.

This early work helps separate essential upgrades from optional improvements, reduces uncertainty and gives the client a clearer basis for scope, budget and schedule decisions.

02

Coordinated transformation

Whether the project is a vacant-shell fit-out, an occupied renovation, a building addition or a change of use, the design must coordinate new work with existing structure and systems. JMA develops the architectural concept and permit documents while coordinating structural, mechanical, electrical and specialty consultants as required.
