— Feasibility · Project Development · Permitting · Owner-Side Delivery
The whole project,
understood as one system.
SOHOXBUILT develops, evaluates and coordinates built-environment projects — from existing conditions and feasibility through project development, permitting and owner-side delivery. Working across sites, infrastructure, buildings, interiors and approvals as one system, we help owners identify requirements earlier, make better-informed decisions and move forward with clearer expectations for scope, timing, cost and delivery, bringing in licensed professionals and specialists where the project requires them.
The practice
One practice across the built environment
Most costly mistakes in property and construction happen before anyone breaks ground: the wrong site, the wrong assumption about what a building can carry, a frontage nobody measured, or a redevelopment plan that no permit path supports. SOHOXBUILT works at that stage and stays through delivery — doing the review, concept, scope, cost and permit-strategy work on the project itself, and coordinating the licensed professionals and specialists each engagement requires.
Technical
What the site, the structure and the ground will and will not allow — read from records, conditions and the right specialist inputs.
Spatial
What the place could become: layout, massing, frontage and interiors informed by global design research, checked against local context, applicable requirements, climate, cost, constructability and long-term performance.
Delivery
The approvals, budget, schedule and coordination that turn a scoped idea into permitted, built work.

Sidewalk & Right-of-Way
The line between private property and the public way is where small elevation differences, missing information and unresolved responsibilities can become expensive construction problems. Sidewalk reconstruction, driveway transitions and right-of-way interfaces are a dedicated SOHOXBUILT capability, and a practical place to start.
- 01
Establish existing conditions
The drawings, prior survey information, spot elevations, photographs and permit comments you already have are reviewed against the site to establish the existing-condition design basis. Where that information is not adequate, field measurement of the existing sidewalk is additional SOHOXBUILT scope, separately priced.
- 02
Develop the proposed sidewalk condition
Proposed spot elevations, cross slopes and longitudinal slopes, driveway transitions, curb and sidewalk transitions, curb reveal, grade breaks, conform points and accessibility-related geometry, checked against applicable City standards, accessibility requirements and permit comments.
- 03
Permit package and coordination
The permit package is prepared and coordinated and review comments are answered. Where the project proposal includes it, contractors, agency processes and any licensed professionals the project requires are coordinated through permit, construction coordination and closeout.
These service levels begin only after a Fit Review, agreed proposal and signed engagement. Field measurement is additional SOHOXBUILT scope, separately priced. Where a project requires a licensed land surveyor or another licensed professional, SOHOXBUILT can coordinate one; those services are separately scoped and priced unless the project proposal expressly states otherwise, and construction is performed by licensed contractors. Permits are decided by the reviewing agency; SOHOXBUILT does not promise approval or a review timeline.
Core capabilities
Where SOHOXBUILT works
Seven practice areas, one way of working. Each has its own page describing the problems it addresses, the services available, what a client may receive and where licensed and agency work begins.
How we work
How SOHOXBUILT approaches every project
The same discipline applies whether the subject is a parcel, a building, a sidewalk or a remodel: understand the actual question, establish what is known and what is missing, do the analysis and development work, name the professionals and approvals the project requires, and document the agreed milestones so the owner can act on them.
The method
Built from seeing where projects slow down.
SOHOXBUILT grew from its founder’s experience across the construction lifecycle — including planning, plan preparation, interdisciplinary coordination, agency review, permitting, field construction and project delivery. Working across those interfaces revealed a recurring problem: projects often lose time and money because requirements, responsibilities and dependencies are discovered only after the work has already advanced.
That experience shaped the structured coordination system behind SOHOXBUILT. Before a project moves forward, the work is examined through the questions likely to be raised by owners, designers, reviewing agencies, contractors and field conditions. Within the agreed scope, requirements, missing information, decisions, approvals, schedule dependencies and cost risks are identified and organized as early as practical.
The objective is not to promise instant approvals or eliminate every revision. It is to prepare more complete and coordinated work, reduce avoidable review cycles and late surprises, and give owners clearer visibility into likely approval paths, sequencing, timing and budget exposure.
We scope before we sell
No proposal is issued until the actual question is understood. A vague scope is how projects lose money.
We are clear about roles
SOHOXBUILT does the feasibility, concept, scope, cost, permit-strategy and owner-side management work directly. Where a project needs a licensed architect, engineer, surveyor or contractor, that role is named and assigned to the right professional.
We write it down
Each agreed milestone produces the documentation defined in the scope, including decisions, assumptions, open risks and recommended next steps where applicable.
We protect the owner's position
Whether we are managing the work or reviewing someone else's, the job is to keep scope, budget and quality aligned with what you approved.
Process and boundaries
From inquiry to scoped engagement
Every inquiry is reviewed by a person before anything is quoted. The initial Fit Review determines project suitability and is not itself an engineering assessment. Substantive analysis begins after the scope and engagement are agreed.
Inquiry
You write to built@thesohox.com with the property address or location, what you are trying to do, and your timing. Start with a conversation and basic project context; there is no obligation. Drawings, surveys and agency correspondence may be requested later through an agreed receipt process. Please do not send sensitive documents with your initial inquiry.
Fit Review
We review the information you provide and enough readily available information to determine whether the project is a suitable fit. Detailed records research and constraint analysis begin only after an engagement is agreed. If the inquiry falls outside what we do, we say so and, where possible, identify the appropriate type of professional.
Scoping conversation
A call or site walk to confirm the actual question, the decisions you need to make, your timeline, and who else is already involved.
Written scope and proposal
The Fit Review and scoping conversation inform a proposed service package, tailored to the project. The written proposal defines services, deliverables, exclusions, fee basis and schedule, and names any licensed or specialist work required. A package is a starting point for that proposal, not an automatic engagement.
Engagement
Work begins on signature. You receive a single point of contact, defined milestones and written deliverables at each one. Where a project requires surveyors, engineers, architects, contractors or other specialists, SOHOXBUILT can coordinate the appropriate parties and agency processes. Third-party professional and contractor services are separately scoped and priced unless the project proposal expressly states otherwise.
Construction is a regulated activity. Stamped engineering and architectural drawings, surveys, geotechnical reports and construction itself are provided by licensed professionals and contractors; title, escrow, legal and tax matters by their own advisers. SOHOXBUILT coordinates these and does not replace them.
Practice areas
Capabilities across the built environment

Inquire
Start a project
Start a conversation at built@thesohox.com with basic project context:
- The property address or general location
- What you own or are considering (site, house, building, frontage, infrastructure issue)
- What you are trying to do, and by when

Initial inquiries are reviewed and answered personally. The initial Fit Review determines project suitability and is not itself an engineering assessment. Substantive analysis begins after the scope and engagement are agreed. Sending an inquiry does not create an engagement; that begins only with a signed scope.
