Plan the Connection Before Building

An addition brings the existing building and new construction together. Review the goals, responsibilities and decisions that shape that connection.

01 / Goals & Daily Use

Define the rooms you need, how you will use them and the connections to the existing home.

02 / Property & Existing Conditions

Review the site, access, available plans and visible conditions. Further assessment may be needed as the scope develops.

03 / Layout & Design

Coordinate circulation, light, storage and how the exterior and interior meet the existing building.

04 / Scope & Budget

Compare the same scope when reviewing addition estimates: structural connections, utility extensions, windows, finishes and work to the existing rooms. Clarify whether design, engineering, approvals and allowances are included. Use the estimator for an initial planning range, then request a property-specific proposal.

05 / Plans & Approvals

Establish design and engineering responsibilities and identify relevant reviews and inspections. Requirements depend on the property and project.

06 / Access & Life at Home

Before deciding to stay during an addition, review how work zones will be separated from occupied rooms, access to a working kitchen and bathroom, and planned utility interruptions. Discuss dust, noise, deliveries and temporary accommodation with the project team before construction begins.

07 / Selections & Materials

Coordinate windows, fixtures and finishes with the design. Review availability and the decisions needed before ordering.

08 / Construction & Changes

Discuss the work sequence, communication and the process for documenting changes to scope, cost or schedule.

09 / Walkthrough & Handoff

Review completed work, outstanding items and available project information before closing the agreed scope.
