Smart Shell Addition™

Climate-Savvy Add-Ons.

Goal: Build small to mid-size additions that solve real space problems (office, bedroom, mudroom, sunroom) while managing water, comfort, and future flexibility.

Tier 1 – Smart Shell Micro-Addition, starting at $25,000

Z
Small footprint bump-out or micro-addition (e.g., reading nook, mudroom, or small office) tied into existing structure with proper footings, framing, and roofing.
Z
Envelope upgrades in the new space: modern insulation, air sealing, and windows sized for light and privacy rather than just square footage.
Z
Basic tie-in to existing HVAC and electrical, with a simple lighting and outlet layout.

Tier 2 – Smart Shell Room Addition, starting at $50,000

Z
Everything in Micro-Addition.
Z
Full new room (e.g., bedroom, larger office, flex room) with structural connections coordinated to preserve or improve existing drainage and roofline.
Z
Upgraded envelope (better windows/doors, enhanced insulation, careful flashing) plus zoning of HVAC supply/return for comfort.
Z
Exterior integration: siding/trim details, roof lines, and a small step, stoop, or landing that integrates with existing walks or patios.

Tier 3 – Smart Shell Suite & Transition, starting at $80,000

Z

Larger multi-purpose addition (e.g., primary suite, family room, or combined office/guest suite) designed to future-proof the home (aging-in-place–friendly layout, good circulation).

Z
Structural and site package: reevaluation of drainage around the new footprint, any necessary grading, and hardscape adjustments (paths, small retaining elements) to protect the addition.
Z
Option to rough-in for future flexibility (e.g., plumbing for a future wet bar/bath, electrical for future kitchenette or studio use).
Z
Interior finish and lighting plan that clearly separates “quiet/sleep” zones from “work/enjoyment” zones while keeping the addition cohesive with the existing house.

Pricing Note:

Prices are for budgetary purposes. Final project costs will be determined by various factors including but not limited to; site conditions, engineering, permitting, finishes, and other unforeseen or site/project specific conditions. Pricing is mid-market and value-based, reflecting durable materials, integrated design, and reduced long-term costs (less erosion damage, lower maintenance, more usable space) rather than competing as the lowest bid. Standardized estimates, clear scopes, and tiered options (good/better/best) help clients choose the right level of investment for their individual needs and goals.
