Construction Consulting
Owner Representation
Suffolk County | Hamptons | North Fork
Building Consultant support for high-end residential projects — planning to punch list
High-end projects out here move fast, and details get expensive. Lead times change, site conditions pop up, and change orders stack up quick when decisions aren’t documented. We provide construction consulting and owner representation so you stay in control of scope, schedule, and budget—without having to manage the whole job yourself.
Based in Southampton, NY, we support projects across the East End of Long Island — Hamptons (South Fork) and the North Fork through Riverhead, including Southampton, Bridgehampton, Sag Harbor, Water Mill, East Hampton, Montauk, Riverhead, Mattituck, Southold, Greenport, and nearby towns.
Availability outside the East End may be limited; if your project is in central or western Suffolk, contact us and we’ll confirm fit and scheduling.
What Is Owner Representation?
Owner representation is hands-on project support designed to protect the homeowner’s interests throughout construction. We act as an organized, experienced point of contact on your side—tracking details, documenting decisions, and helping ensure contractors, consultants, and vendors stay aligned with the scope, schedule, and expectations.

If you want help deciding what to tackle before listing, we can provide construction consulting support to:
Most clients choose one of these setups:
Hourly consulting for targeted help (change orders, bid comparisons, walkthroughs, scope questions)
Monthly support for ongoing oversight during active construction (site meetings, tracking decisions, documentation)
Milestone support when timing matters (rough walkthrough, pre-close, punch list, closeout)
Not sure what level of support you need? Send the project town and where you are in the process (planning, active build, closeout). We’ll recommend the best starting point.

FAQ
What is owner representation?
Owner representation (owner’s rep) is owner-side support during a renovation or build. We help keep scope, schedule, and budget clear, and we document decisions so the project stays organized. We work for you—not for the contractor.
Are you the general contractor on the project?
No. We are not acting as the general contractor. We provide consulting and oversight support, and we coordinate with your existing team (GC, architect, engineers, designers).
What’s the difference between construction consulting and owner representation?
Construction consulting is targeted help (change orders, bid review, walkthroughs, punch list). Owner representation is more ongoing support—site meetings, tracking decisions, documentation, and keeping the team aligned through the build.
Can you step into a project that’s already underway?
Yes. We can step in mid-project to organize documentation, review change orders, tighten communication, and help stabilize the schedule and next steps.
How do you handle change orders?
We review change orders for scope clarity, pricing logic, and schedule impact. The goal is to reduce vague language, avoid overlap, and help you make confident approve/decline decisions.
What should I do before the appointment?
If you can, share any background: known leaks, recent storms, past repairs/remediation, where odors show up, and where staining is visible. Try not to do heavy cleaning of suspect areas right before the visit—documentation is easier when conditions are undisturbed.
Do you perform post-remediation verification?
Yes. After remediation or repairs, we can perform post-remediation / post-repair verification to document current conditions and confirm the work matches the intended plan. When appropriate, that can include follow-up measurements or air monitoring.
Can you help if I’m not local full-time (seasonal home)?
Yes. A lot of East End clients use owner representation because the home is seasonal or they travel. We help keep momentum and keep you updated with clear notes and documentation.
Do you attend site meetings and provide meeting notes?
Yes. When requested, we attend site meetings and provide clear meeting notes with action items and owners, so nothing gets lost between trades.
Can you help compare contractor bids?
Yes. We can compare bids apples-to-apples, identify missing scope or exclusions, and help you ask the right questions before you sign.
Do you create punch lists?
Yes. We can walk the job near the finish line and produce a punch list with clear items so closeout doesn’t drag out.
Will you recommend contractors or specialists?
We can recommend the right type of contractor or specialist when needed. Final selection is always up to you, and we stay owner-side.
What types of projects do you support on the East End?
High-end residential renovations, additions, and custom work across the Hamptons and North Fork. Common requests include scope clarity, change order review, documentation, and closeout support.
What areas do you cover?
We cover the East End of Long Island — Hamptons (South Fork) and the North Fork through Riverhead, including Southampton, Bridgehampton, Sag Harbor, Water Mill, East Hampton, Montauk, Riverhead, Mattituck, Southold, Greenport, and nearby towns.
If you’re planning a custom build or managing a complex renovation, we can help you stay in control of the details.
