Answer a few questions about your lot, structure, and goals. The Addition Feasibility System™ scores eight structural and zoning variables and produces a ranked Build Out Blueprint™ — what's feasible, what's a stretch, and what to check with your municipality before you spend a dollar on design.
Archetype, lot orientation, age, and what kind of space you're hoping to add — a garage conversion, a second story, a rear addition, or something you're still deciding on.
02
We Score the Constraints That Matter
Zoning setbacks, HOA and historic overlays, utility access, and structural condition are weighed together — not just whether an addition is possible, but how hard it would be.
03
Get Your Build Out Blueprint™
A ranked feasibility report you can bring into a design consultation — what's straightforward, what needs a variance or engineering review, and what to budget for first.
Common Questions
Before You Start
Is this actually free?
Yes. No credit card, no obligation, and it takes under three minutes. You'll get a ranked feasibility report before you talk to anyone.
Does this replace a zoning review or structural engineer?
No. It's a fast first read based on what you report about your property — a licensed review is still how final feasibility and scope get confirmed. Think of it as knowing what to ask about before that conversation happens.
I'm not sure yet what kind of addition I want — is this still useful?
Yes. The assessment works from whatever you know today, and flags where "unsure" answers affect your feasibility score so you know what to firm up first.
What happens after I get my Blueprint?
You can schedule an in-home consultation directly from your results — nothing is decided or booked until you choose to take that next step.

Screen 2 · Asset Investment Intent
What are you trying to accomplish?
Your goal shapes which expansion archetypes the system weights most heavily. Select the option that most directly describes your objective.
Primary Space Goal
🛏️Add Bedrooms / BathsExpanding household or family needs
🍳Expand Kitchen / Living AreaOpen the main living footprint
👨👩👧Multi-Generational SuiteIn-law suite or separate living space on-site
💼Home Office / StudioDedicated workspace or creative studio
💰Rental Income UnitADU or separately rentable living space
📈Maximize Resale ValueStrategic expansion for market performance
Target Ownership Horizon
Short-Term<3 years
Mid-Term3–7 years
Long-Term7+ years
Screen 3 · Physical Site Logistics
Describe your property's physical constraints.
Site conditions are among the most decisive variables in determining which expansion paths are structurally and logistically viable.
Lot Orientation
📐Interior LotFlanked by neighboring properties on both sides
↗️Corner LotStreet frontage on two sides — may offer setback flexibility↑ Potential setback advantage
Side Yard Access (Machinery Clearance)
🚛Wide OpenFull-sized equipment can access the backyard
🚶ModerateFoot traffic or wheelbarrow access only
⛔Tight / Blocked<6 ft clearance or blocked entirely⚠ Ground addition cost pressure
Topography / Site Grade
➖Flat / LevelStandard foundation conditions throughout
📉Moderate GradeSome slope — manageable with standard prep
⛰️Steep SlopeFoundation steps or retaining assemblies likely required⚠ Foundation complexity elevated
Screen 4 · Infrastructure & Mechanicals
What's the mechanical baseline?
Mechanical infrastructure determines how an addition integrates with your existing systems — and where cost exposure tends to be highest.
Primary HVAC Core
💨Forced Hot Air & Central AC
🌡️Radiators / Hot Water Boiler⚠ Independent zone likely

Screen 6 · On-Site Disruption Thresholds
How will you live through the build?
Construction occupancy and household disruption tolerance are among the most decisive variables for path selection — particularly for vertical additions.
Construction Occupancy
🏠Living On-Site During BuildWe intend to remain in the home throughout construction
📦Planning to Temporarily RelocateWe can vacate for the full duration of construction
Disruption Tolerance Level
🔇LowSpace must remain sealed and sound-isolated throughout
⚖️MediumNormal routine can adapt around construction activity
🔨HighFully prepared for an active construction environment
Screen 7 · Structural Trade-Off Priority
What matters most to you?
When trade-offs arise — and they always do — this determines which axis the system uses to rank competing paths. Select the single most important driver.
💸Minimize Capital OutlayAchieve the objective with the most efficient use of capital
📐Maximize Square Footage YieldPrioritize total usable area added to the structure
🏷️Prioritize Resale VelocitySelect the path most likely to increase market value at sale
🛡️Protect Daily Living RoutineMinimize household disruption above all other considerations
Screen 8 · Capital Alignment
Define your financial parameters.
Capital allocation and funding channel are the final structural variables. These determine which path architectures are financially viable and which must be suppressed.
Projected Capital Allocation
Under $125kSuppresses major structural paths — hybrid approaches elevated
$125k – $200kGround-level additions and phased approaches viable
$200k – $350kFull structural expansion paths available
$350k+All structural paths including vertical extension fully viable
