Commercial Additions & Facility Expansions Contractor in Durham Region, ON

Henley Contracting builds additions and expansions to commercial and industrial buildings across Durham Region. When a business runs short of space, adding on to the building it already owns can be faster and less disruptive than moving. We plan each expansion around the site, the existing structure and the operation that has to keep running.

ADDITIONS & FACILITY EXPANSIONS · DURHAM REGION

Commercial additions across Durham Region

An addition can bring more production floor, warehouse space, offices or a new customer entrance without giving up a location your staff and customers already know. The right answer depends on how much room the lot has, how the existing building was built and what the local municipality allows.

We look at all three before a design is drawn.

  • 01 / SITE FIRST

    Setbacks, parking, loading and drainage reviewed early.

  • 02 / EXISTING BUILDING

    Structure, foundations and services checked where the new part connects.

  • 03 / OPERATIONS

    Work planned so the business keeps running.

  • 04 / ONE CONTRACTOR

    Design team, trades, permits and inspections coordinated for you.

Site plan approval

Many commercial additions need site plan approval as well as a building permit, and the rules differ in each Durham municipality. We help you find out early what applies, so the design and schedule account for it.

Building in phases

A larger expansion can be built in stages, with each stage finished, inspected and in use before the next begins. Phasing spreads the cost and keeps disruption to one area at a time.
