WHAT WE DO
What we Build
Commercial Construction
We help business owners design & build their space for commercial success. We’re your turn-key partner in understanding your business, catering to your customer’s needs, and facilitating the design and build process for commercial success. We deliver complete build-out construction for your commercial unit.
We build custom homes designed for long-term living and enduring value. As your trusted builder in Durham, we shape each project around your lifestyle, future plans, and property goals. We deliver ground-up builds and substantial residential expansions built to support your vision.
Emstone takes responsibility for the full construction scope. From early coordination through on-site execution, projects are led by one accountable team responsible for decisions, sequencing, and outcomes.
Decisions Locked Before Work Begins
Major decisions are resolved before work begins. Scope alignment, technical coordination, and sequencing are addressed upfront to reduce change, rework, and avoidable risk during construction.
Leadership Through Completion
Oversight does not end once work starts. Our Leadership remains involved through construction and closeout to ensure standards are maintained and the project is delivered as intended.
These standards apply to every residential and commercial project we take on, regardless of size or complexity.
OUR PROCESS
Our Build Approach
01
Discovery & Site Visit
We start by walking the site with you and understanding what you want to build, what’s possible, and what constraints we’re working within.
02
Design & Drawings
Plans and drawings are developed to reflect the layout, structure, and building systems needed to support the project.
03
Final Budget & Timeline
You’ll get clear numbers and a realistic timeline. We flag what’s locked in, what could shift, and where variables like permits or structural changes may affect the schedule.
04
Permits & Site Prep
We coordinate required permits & approvals and the site is prepared so construction can begin without unnecessary delays.
05
Construction
Work moves forward with ongoing oversight and coordination between trades. Progress is reviewed regularly to keep things aligned with the plan.
06
Closeout
Once the work is complete, we walk the project with you, address final items, and complete close-out before handing things over.
