Published: February 11, 2026

In our latest episode of KBB’s From the Tap podcast, architect Lauren Thomsen, principal of Philadelphia-based Lauren Thomsen Design, talks about the challenge of modernizing older homes while honoring their character and incorporating sustainable systems.

The conversation begins with navigating technicalities, with Thomsen noting that work on older properties often requires special approvals from the building department and other agencies. She talks about the permitting process and ways designers and architects can best prepare for it.

Next up: working with owners of older homes. Thomsen offers advice to designers on helping clients understand what can and can’t be done structurally to a heritage home, both inside and out. She goes into detail on the issues of aesthetic and historic appropriateness, which can be a delicate negotiation with some clients. Thomsen offers additional insights on managing homeowners’ expectations when it comes to scheduling and budget, as well.

Thomsen continues to share her experiences with building relationships with contractors and tradespeople who have the patience and skill to update older residences. She talks about sourcing period-authentic or appropriate materials, and the challenges – and solutions – of retrofitting or updating mechanical systems.

The podcast concludes with Thomsen discussing her work on kitchens and bathrooms that are situated in historical buildings. These include Philadelphia’s beloved row houses as well as mid-century homes in the surrounding suburbs.
