My story

The first renovation I ever worked on as the lead designer was a tired 1890s farmhouse outside Rhinebeck — three bedrooms, a load-bearing post in the middle of what the owners called “the new kitchen,” and a contractor who had already framed half the addition before anyone bothered to actually study the original plan. We pulled the plan out, sat with it for an afternoon, and rewrote almost everything that hadn’t been built yet. The kitchen moved six feet east. The dining wall came down. The pantry stopped being a hallway. That was the project that taught me that most renovations don’t go wrong on the job site — they go wrong on the plan that nobody read carefully enough.

I had spent four years as an architectural drafter producing construction documents — clean line weights, perfect dimension strings, every callout in the right place — and exactly zero of those years learning to read a floor plan the way an owner reads it: at the breakfast counter, at the coat closet on a Tuesday morning, in the mudroom with three pairs of muddy boots and a wet dog. The plans that hold up are the ones that survive that kind of daily testing — not the ones that document well.

By 2022 I had walked through enough plans (mine and other people’s, both pre-renovation and post) to notice what the good ones share. Sensible circulation. A kitchen that does not need to be the largest room in the house to feel generous. A primary suite placed where the morning sun actually hits it. Mechanical chases that respect the structural bay. Door swings that do not collide. Boring stuff. Quiet stuff. The stuff that costs nothing on paper and saves you fifteen years of friction once you are living in it.

I launched Renovate and Plan in 2026 to put it all in one place. Today I run the House Plans desk: honest plan reviews from the Architectural Designs marketplace, with a renovator’s eye on what would actually live well over time. Written from a Hudson Valley desk, for everyone who believes a great renovation starts with reading the plan first.

How I work

Read Before You Renovate

Every plan review asks the same question: what would a careful read of the original plan have told you, before anyone started taking walls down?

Honest Plan Reviews

I review plans the way I would renovate one — what works, what fights you, who it actually fits, and what it would take to make it better. No affiliate-driven fluff.

Quiet Wins Over Visible Ones

A removed wall does not fix bad circulation. The structural moves you barely see are the ones that age the best.

Lived-In Beats Photo-Perfect

A plan that ages well is one designed for the daily friction — the wet boots, the school bags, the bad-weather Sundays — not for the listing photo.

Areas of expertise

House Plan Reviews

Architectural Designs marketplace plans walked through with a renovator’s eye — what each design promises, what it actually delivers, and what would need to change for the next owner to love it.

Floor Plan Analysis

Sight lines, room proportions, ceiling moves, structural bays, mechanical chases, and the small layout decisions that quietly make or break a home.

Cost-to-Build Estimates

Line-item 2026 Northeast build costs for every plan reviewed — site work to finishes — so the number on the listing becomes a number you can plan around.

Facade & Massing

How the same footprint reads under different elevations, roof forms and cladding systems — and which variants are genuinely different rather than cosmetic.

Where I work

Climate, vintage and structural code all change what a renovation should do. Most references land within this radius:

Design journey

  1. 2018

    First Year on the Boards

    Started as an architectural drafter at a small Hudson Valley residential office. Spent the year producing construction documents and learning what a real plan set has to carry.

  2. 2020

    Moved Into Renovation Design

    Shifted from drafting into renovation design after watching one too many projects unravel because nobody had really read the plan before the demo started.

  3. 2022

    Started Writing

    First long-form essays on plan-aware renovation and floor-plan reviews, written as pre-flight notes for clients; the public audience came on its own.

  4. 2024

    The Audience Builds

    Owners doing their own homework, builders, and other designers started forwarding the essays. The plan-literacy gap was much wider than assumed.

  5. 2026

    Renovate and Plan Launches

    Seven years bridging drafting and renovation, hundreds of plans walked through, pulled into a single publication. Hudson-Valley-based, design-build-led, plan-first.
