GL Lewis Construction Services – ADU Builder in Central Florida
GL Lewis Construction Services is a licensed Florida General Contractor (License #CGC1528896) specializing in the design and construction of Accessory Dwelling Units (ADUs), including granny flats, studio suites, and backyard cottages. Their focus is on traditionally built, personalized homes that are designed to provide long-term value for property owners and meaningful housing options for families.
As a dedicated ADU contractor, GL Lewis Construction manages every aspect of a project from initial evaluation through to construction and warranty. Their process is structured to reduce risk and provide transparency at every stage, typically completing builds within a timeframe of three to six months.
A Structured Approach to Building Your ADU
GL Lewis Construction follows a clear, three-step process to guide homeowners through what can otherwise be a complex undertaking:
- Evaluation: Before any design work begins, GL Lewis Construction assesses what is actually buildable on a given property. Regulations around setbacks, rear yard coverage, location, and materials are subject to change, and navigating those requirements is a core part of their service. This step ensures homeowners understand both their options and their budget constraints upfront.
- Design: As a design-build company, GL Lewis Construction maintains a library of floor plans and designs developed with architectural and interior designers. Many of these plans are pre-approved by counties and cities across the Central Florida area, including Volusia, Deltona, and DeLand. Pre-approved plans help reduce third-party design costs and streamline the permitting process. Homeowners are presented with floor plan options suited to their property, along with interior design packages and optional premium upgrades for further personalization.
- Build: Once design and permitting are underway, GL Lewis Construction provides a detailed cost breakdown, defines the construction schedule, and manages material procurement. A Pre-Production Meeting is held on-site to address practical details before construction begins. Their design team also handles permit submissions and any required adjustments with building or planning departments.
Throughout the process, GL Lewis Construction aims to answer three key questions for every homeowner: Can I build an ADU? How much will it cost? And how will it all get done? Their role is to provide clear, honest answers to each of these before any commitment is made.
Pre-Approved ADU Floor Plans and Customization Options
GL Lewis Construction has developed one of the larger libraries of pre-approved ADU plans available in Central Florida, covering areas including Deltona, Sanford, DeBary, DeLand, and counties such as Volusia, Seminole, and Orange. A pre-approved plan has already been reviewed by the relevant City or County Building and Planning department, which reduces permitting time and eliminates uncertainty — provided the design is not altered.
Available pre-approved floor plan sizes include:
- 748 sq ft – 2 Bedroom / 2 Bath with full kitchen and living room
- 560 sq ft – 1 Bedroom / 1 Bath with full kitchen and living room
- 440 sq ft – 1 Bedroom / 1 Bath with full kitchen and living room
- 364 sq ft – 1 Bedroom / 1 Bath with full kitchen and living room
These are not factory-assembled or modular units. GL Lewis Construction builds traditionally constructed homes with a range of interior package options and upgrades available. Homeowners can select from design aesthetics, ceiling heights, bathroom configurations, exterior finishes, roofing styles, natural light features, storage solutions, and HVAC options, among others. This level of customization allows each accessory dwelling unit to be tailored to the specific needs and preferences of the homeowner.
GL Lewis Construction Services positions itself as a specialist ADU builder for Central Florida property owners looking to add a functional, independently livable structure to their property — whether for family use, long-term housing planning, or added property value.
