Home additions & extensions.

Capitol Concrete undertakes home additions and extensions as complete construction projects. We discuss how the new space connects to the existing home, from excavation and foundations through the coordinated building work.

Free consultation. No obligation.

Start with the space you need

Tell us how the addition should change the way you use the house: more living space, a different layout or room for another function. Available drawings, desired size and finish expectations help define the next steps. Early conversations also identify what design information is still needed.

Understand the old-to-new connections

An addition meets existing foundations, walls, roof lines and building systems. These interfaces need coordinated design and construction responsibilities. The scope should identify the new work, alterations to the existing home and any assessment needed before openings or connections are made.

Plan around an occupied home

Equipment access, temporary routes, protection and the sequence of disruptive work affect daily life during construction. Discuss which parts of the home must remain usable and any timing constraints. Changes to selections or scope are documented with their cost and schedule implications before changed work begins.

Pricing the complete scope

What affects the estimate?

Size, structural connections, foundations, site access, utility changes and finish selections influence an addition estimate. Include the work needed inside the existing home; pricing only the new footprint can miss a significant part of the project.

Before we meet.

Start with the property address and a description of the work. These details help us prepare for a useful conversation:

  • A description of the intended rooms and how they connect to the house
  • Photos, drawings and any existing design or approval information
  • Living arrangements, finish priorities and timing constraints

We discuss the scope and arrange a site visit. Your proposal identifies the included work, responsibilities and project-specific warranty terms. Changes to scope, cost or timing are documented before the changed work begins.
