Construction Services in Northern Utah

This page is for homeowners planning a project that is too large or too layered for a single trade to handle on its own. That typically means:

(i) Homeowners adding space — room additions, second-story additions, bump-outs, or living-space expansions where the existing structure connects to new construction.

(ii) Homeowners building a detached structure — garages, shops, outbuildings, or accessory structures that need their own foundation, framing, enclosure, and finish sequence.

(iii) Homeowners rebuilding after damage or deterioration — rebuild scopes where structural failure, water damage, fire damage, or long-term neglect requires removing compromised sections and constructing replacement structure and finishes.

(iv) Homeowners managing a multi-phase renovation — projects where demolition, structural changes, mechanical rough-ins, and finish work need to be sequenced across weeks or months rather than completed in a single visit.

Requested-role boundary: When the project requires trade coordination beyond Cornerstone's S220 classification, we clarify which responsibilities belong to us and which need a licensed general contractor, engineer, or specialty trade before estimating. This boundary is discussed during the estimate conversation, not assumed.

What this service typically covers:

(i) Large additions and expansions — connecting new living space to an existing home, including foundation tie-ins, framing extensions, roof integration, and finish work through the transition.

(ii) Detached structures — garages, shops, storage buildings, and other freestanding builds that follow a full construction sequence from site prep through final finish.

(iii) Rebuild and restoration scopes — removing damaged or deteriorated structure and replacing it with new framing, sheathing, enclosure, and interior buildout.

(iv) Multi-phase renovations — projects staged across several rounds of work where demolition, structural modifications, rough-ins, and finishes each happen in a planned order.

(v) Shell-and-finish projects — completing the structural envelope (foundation, framing, roofing, windows, doors) with interior finishing as a continuous or phased scope.

What this page does not cover:

Ground-up new homes, commercial buildings, and multifamily construction are handled under the New Construction Projects family. Single-trade work like a standalone flooring job, a paint refresh, or a fixture swap belongs on the specific service page for that trade. If you are not sure whether your project fits here, call and we will help you find the right path.

Representative project conditions:

Larger construction projects often involve occupied homes, phased access, seasonal scheduling, permit sequencing, adjacent landscaping or hardscaping, utility relocation, and coordination with homeowner selections for finishes, fixtures, and materials. These conditions affect both the estimate and the build schedule.

Construction projects at this scale typically fall into one of four categories. Each one involves a different planning path, and the estimate conversation starts by identifying which category fits your project.

Additions and expansions — Adding livable square footage to an existing home. This includes room additions, second-story additions, and bump-outs. The scope requires tying new structure into the existing foundation, framing, roofline, and mechanical systems. Structural integration, roof lines, and exterior-match details drive the complexity.

Detached structures — Building a freestanding structure on the same property. Garages, shops, outbuildings, and accessory buildings each follow a standalone construction sequence — site prep, foundation, framing, dry-in, and finish — without the integration challenges of an attached addition.

Rebuilds — Replacing compromised structure and finishes after damage or long-term deterioration. Rebuild scope often begins with demolition, may involve foundation repair, and typically requires framing new sections before interior finish work can begin.

Multi-phase renovations — Staging a large renovation across planned rounds of work. Each phase has its own demolition, rough-in, and finish sequence. Phased renovations are common when the homeowner stays in the home during construction or when budget, permitting, or seasonal timing requires breaking the project into stages.

Construction projects at this scale require more planning detail than a single-trade estimate. Gathering this information before your first call gives us a clearer starting point and reduces the number of follow-up conversations before the estimate is ready.

Property and site:

(i) Property address or city and ZIP code

(ii) Lot size, slope, access from the street, and where the proposed work sits relative to the existing home

(iii) Known utility locations (water, sewer, gas, electrical service) near the work area

(iv) Any HOA, easement, setback, or zoning restrictions you are aware of

Project scope:

(i) What you are building or changing — addition type, detached structure, rebuild area, or renovation scope

(ii) Approximate size of the new or modified space (rough dimensions or square footage)

(iii) Current planning stage — concept, sketches, architectural drawings, engineered plans, or permit-ready documents

(iv) Whether engineering, architectural plans, or a survey have already been completed or still need to be arranged

Timing and conditions:

(i) Target start window and any hard deadlines (lease end, seasonal, family timing)

(ii) Whether the home will be occupied during construction

(iii) Access constraints — narrow driveways, shared lots, fenced yards, overhead utilities, or staging limitations

(iv) Known permit status or prior conversations with your city or county building department
