Single-Family Residences
Designing Private Homes That Balance Beauty and Function
Single-family homes in New York require more than good design—they demand skillful navigation of zoning, space limitations, and historic constraints. William Leggio Architect LLC works with homeowners to create refined, context-driven residences that meet daily needs and long-term goals.
From brownstone renovations to modern infill homes, every project begins with a deep understanding of the site, the structure, and the people who will inhabit it. The result is a residence that feels tailored, livable, and lasting.
This work involves far more than architectural styling. It’s about spatial flow, structural alignment, regulatory strategy, and thoughtful material selection—done with the care and clarity of a firm deeply familiar with the city’s complexities.
A Design Process Grounded in Personalization
Single-family homes are personal. We begin by understanding how each family uses space. Do you need room for entertaining? Quiet zones for work? Future flexibility for growing families? These factors shape every part of the design.
The process is collaborative and transparent:
- Initial consultation and feasibility
- Conceptual design and layout strategy
- Material selection and detailing
- DOB coordination and drawing sets
- Construction observation and support
Throughout, William Leggio remains directly involved—ensuring the finished product matches both vision and expectations.
