HARRISON, TN – November 06, 2026 – PRESSADVANTAGE –

Big Dog Development, a residential construction company based in Harrison, Tennessee, has expanded its custom home build and addition services to include second-story additions, garage conversions and expanded room additions for homeowners across the greater Chattanooga area. The expansion brings design, construction and project management for both new custom homes and home additions under a single four-stage process the company has developed over more than 13 years in residential construction.

The updated lineup covers ground-up custom home construction alongside additions such as bedrooms, bathrooms, sunrooms, second-story expansions and garage conversions. Company representatives said the changes were made to give homeowners a clearer path from initial consultation through final walkthrough, rather than treating design, permitting and construction as separate phases handled independently. The company is locally owned and operated, and it said its familiarity with building codes and construction requirements across the region shaped how the expanded services were structured. Second-story additions and garage conversions are now assessed through the same design and permitting review already used for new custom home construction, rather than being scoped as smaller, separate projects.

Matthew Shannon, owner of Big Dog Development, said the expansion reflects homeowner demand for additional living space without relocating. “Families are asking for more room, whether that means a second story, a converted garage or a full addition, and the process needs to stay organized from the first sketch through the final walkthrough,” said Shannon. The company said its four-stage process is intended to keep custom home builds and additions on a consistent schedule regardless of project size, with the same team handling design, permitting and construction oversight rather than passing a project between separate crews for each phase.

The process begins with a consultation and vision-planning stage, in which project goals, preferences and budget are established before any design work begins. That is followed by a design and architectural planning stage, during which layouts and material selections are developed to meet local code requirements while accounting for the structural demands of additions such as second stories. Construction and project management make up the third stage, covering trade coordination and scheduling from foundation work to finishing. A final walkthrough closes out each project, giving homeowners a chance to review completed work before it is turned over.

Under the expanded offering, second-story additions can add bedrooms, bathrooms or private living suites while preserving a home’s existing footprint, and garage conversions turn unused space into guest suites, home offices or recreational rooms. Room additions, including bedrooms, bathrooms and sunrooms, are designed to match the style and layout of an existing home rather than appear as a separate structure. Big Dog Development said permitting, inspections and code compliance for these projects are handled directly by the company rather than referred to outside services. Additions such as second stories and garage conversions are typically chosen by homeowners who want more living space without the cost and disruption of relocating to a different property.

The expanded services are available to homeowners in the seven communities Big Dog Development lists as its primary service area: Chattanooga, Harrison, Signal Mountain, Red Bank, Collegedale, East Ridge and Soddy-Daisy. Company representatives said project pricing and timelines vary by scope and are determined after an initial consultation, with each project following the same four-stage process from design through construction to final walkthrough. Big Dog Development has operated in the region for more than 13 years, working on projects that range from single-room additions to full custom home construction, and the expanded lineup is intended to keep that range of work under one coordinated process. Homeowners considering either a full custom build or an addition go through the same initial consultation step before a project scope or timeline is set.
