Harrow is a small residential development house. We accept a limited number of partners each vintage, source nearly all of our work off-market, and build with the kind of materials and craftsmen that cost more upfront and cost less over decades.
The work is selected, not scaled. The reporting is fiduciary, not promotional. The capital is closed network, never solicited.
Harrow was founded in 2019 by two partners who, having spent the prior decade in larger residential firms, became persuaded that the most durable returns in the asset class were not coming from scale, but from restraint — from a willingness to source patiently, build slowly, and reject the deals that did not pencil to a 24-month downside.
The thesis was unfashionable at the time, and it remains unfashionable now. The advantage of an unfashionable thesis is that very few firms are willing to operate against it for very long.
Most residential developers will tell you that the limiting factor in their business is capital. That has not been our experience. The limiting factor in our business — and we suspect, in any serious residential business — is the supply of off-market parcels of correct vintage, correct basis, and correct entitlement risk.
There is a great deal of capital chasing residential deals at any moment in any cycle. There are very few good deals at any moment in any cycle. Our work is to be among the operators who see them first.
We have therefore organized the House around the relationships that produce good deals, not the marketing that produces commitments. Every parcel we have closed since founding has come to us through a relationship — a broker we have closed with before, an attorney representing an estate, an operator who has sold to us once and prefers our process to the open market.
This is, we recognize, a slow way to build a development firm. We are content for it to be a slow way to build a development firm. The compounding is on the other side of the patience.
Each Harrow project is governed by the same five commitments — applied without exception, in writing, on every deal we have ever closed.
Every parcel comes through a relationship. We do not bid in auctions, we do not subscribe to deal-flow services, and we do not pursue properties marketed on a portal. The discipline of the relationship is the discipline of the basis.
Every deal is underwritten to three scenarios — base, downside, stretch. If the downside scenario does not pencil to break-even on a 24-month hold, the deal does not clear committee. Survival precedes return.
The House contributes a minimum of ten percent equity on every deal — alongside our partners, in the same vehicle, with the same exposure and the same waiting line. We earn promote only after LPs earn pref.
Quarterly construction reports. Monthly draw documentation. K-1s issued by March 15 each year. Investor portal access for every LP, every deal — including pre-construction and exited projects.
The House does not advertise. We do not publish a deal pipeline. We accept new partners by introduction from existing partners — and we keep the total LP count well under what most firms of our vintage maintain. This is, in our view, an asset.
A row of ten ground-up homes built in continuity with the surrounding 1880s brownstones. Cornice profiles matched. Interior millwork from a local shop. Delivered without a single capital call.
Adaptive reuse of a 1922 industrial structure. Twelve loft residences. Sawtooth roof preserved; freight elevator retained as the building's signature.
Three adjacent townhouse restorations executed as a single coherent project. Historic facades preserved; interiors reimagined for contemporary families.
Six boutique homes arranged around a shared cobblestone mews. The House's first project with private courtyards, designed in collaboration with a Philadelphia landscape architect.
"The most valuable thing a residential development firm can build over a decade is not a portfolio. It is the small set of relationships that produce the next portfolio."
Harrow welcomes a small number of new partners each vintage. Introductions are preferred and most easily made through existing partners. Direct inquiries are received quietly, considered carefully, and answered within ten business days.
