Fabl Design plans additions, remodels, ADUs, and custom homes for Carmel homeowners across Hamilton County. We work from Indianapolis, know how Central Indiana reviewers read a set of drawings, and handle the zoning details before they turn into redesigns.
Every service we offer, delivered locally — with drawings your builder and your permit reviewer will both understand.
From first sketch to construction-ready plans, we shape spaces around how you actually live — additions, remodels, ADUs, and new custom homes.
Site planning, hardscape, and planting design that connects your home to its yard — patios, entries, and outdoor living that feel like part of the architecture.
Photoreal interior and exterior renderings so you can walk your project, make decisions with confidence, and align every stakeholder.
Measured, verified documentation of your existing home — the foundation any thoughtful remodel or addition should start from.
We prepare, package, and shepherd your submittals through the local review process — so your project keeps moving.
A curated network of vetted builders we've worked with — matched to your scope, budget, and timeline.
Before design begins, confirm the district your lot sits in. The Carmel zoning map lets you search by street address or parcel number and shows the base district plus any overlays that affect what you can build.
Zoning maps are for general research only. Verify districts, overlays, and permitted uses with the Carmel planning department before making decisions — or send us your address and we'll confirm it for you.
The district your lot sits in sets your setbacks, height, and how much of the site you can cover. Here's a quick reference we use during schematic design in Carmel.
Very low-density estate district for large single-family lots, often on private wells/septic or rural-character streets.
Low-density single-family district common in larger-lot subdivisions across Carmel.
Standard single-family residential district covering many long-established Carmel subdivisions.
Moderate-density single-family district with smaller minimum lot sizes than R-1, used in many newer neighborhoods.
Higher-density single-family and patio-home district permitting smaller lots for detached homes.
Allows two-family and low-rise multi-family dwellings alongside single-family homes near mixed-density areas.
Higher-density multi-family residential district used for townhomes and apartment communities.
Typically developed under a planned unit development (PUD) or platted site plan rather than a standard subdivision lot.
Covers the original platted core of Carmel and applies architectural and design standards to preserve its historic character.
Overlay zone along key corridors such as Meridian Street (US 31/421) establishing enhanced landscaping, signage, and building placement standards.
Applies to properties within FEMA-mapped special flood hazard areas along Carmel waterways such as Williams Creek and the White River.
Design-based overlay applied to the Village of WestClay and similar traditional-neighborhood-design communities to maintain a consistent architectural pattern.
These figures are general guidance for early planning — final requirements depend on your parcel, overlays, and any prior variances. Verify with the Carmel codes department or the official zoning ordinance. We confirm them for your address before design begins.
This project expands an existing home with a new two-story addition, larger L-shaped front porch, and new side entry. The addition includes a garage on the lower level and a 340 SF office on the second floor, accessed directly from the existing home's upper level. Matching shed dormers and aligned roof forms bring more natural light, increase usable space, and create a stronger connection between the existing house and the addition. The result is a larger and more functional home that maintains the character of the existing residence.
This project completely remodels and expands an existing home with a new sunroom, enlarged primary suite, large side addition, and expanded front porch. The design opens up the previously divided interior, creating stronger connections between the kitchen, living, dining, front porch, and backyard. A new garage and workshop take advantage of the site's changing grade, while the additions are carefully integrated with the existing home's scale, materials, and roof forms. The result is a more spacious, connected, and functional home designed to support both the homeowners' current and future needs.
This project adds a multi-level garage addition to an existing single-family home, connected through a two-story connector that improves circulation between the house, the garage, and the backyard. Responding to the site's changing grade, the design integrates multiple garage levels while introducing a new deck, contemporary material palette, and generous glazing. The result is a functional addition that complements the scale and architectural character of the existing home.
Residential additions and remodels in Carmel are reviewed by the Department of Community Services (Planning & Zoning division), which handles zoning compliance, and by the Building Division for building permits and inspections. Most single-family additions that meet the base district's setback, height, and lot coverage standards can be approved administratively without a Board of Zoning Appeals hearing. Homes inside the Old Town District Overlay need Site Plan and Design Review (SDR) approval from Planning & Zoning before a permit is issued, and parcels in a PUD are reviewed against that community's PUD ordinance rather than the base district standards.
