This project reimagined a single expansive space into two distinct, market-ready spec suites designed to attract tenants with elevated finishes and thoughtfully curated layouts. Suite 640 embodies the signature spec suite aesthetic — a bright, airy environment with soft neutral tones, clean lines, and an inviting open feel. Beyond the glass double doors, the OTS-style Entry and Reception flow seamlessly into the open work area, where natural light enhances the connection between the Copy/Print and Break areas. The Break area features a sophisticated stone countertop, while a glass walled Conference Room with a striking wallcovering adds depth and visual interest. In contrast, Suite 630 offers a darker, more dramatic palette, appealing to tenants seeking a refined, modern atmosphere. The OTS-inspired Reception opens to a glass-enclosed Conference Room, maintaining openness and visibility throughout. Beyond, two private offices, a Copy/Print area, and an integrated Open Office and Breakroom provide balance between collaboration and focus. By efficiently transforming one large suite into two highly marketable spaces Cornerstone Contracting Group delivered design flexibility and quality craftsmanship ahead of schedule — reinforcing our commitment to creating environments that inspire productivity and reflect the unique identity of every future tenant.

Cornerstone Contracting Group partnered with RG-RE to reimagine a long-vacant suite into a vibrant, market-ready space that reflects RG-RE’s vision of creating inviting, functional environments for modern tenants. From the moment you step inside, the space makes a statement — bold, eye-catching wallcovering adds color and energy, setting the tone for the rest of the suite. A striking glass-front conference room extends to the exterior windows, framing sweeping views of the city and surrounding treetops. The layout flows seamlessly into an open area with an exposed ceiling concept, complemented by four private offices with full glass fronts that enhance natural light throughout. The copy area features sleek new laminate millwork, paired with a generous storage room for functionality. Tucked away, the beautifully designed kitchenette showcases laminate millwork with quartz countertops, floating shelves, and a custom ceramic tile backsplash. Through thoughtful planning, collaboration, and value engineering, CCG delivered a dynamic, high-quality space that balances style, function, and budget — perfectly aligning with RG-RE’s goal of attracting and inspiring future tenants.

We're hiring superintendents at Cornerstone — both entry-level and experienced.

If you've got experience:

You know what this job is. Run the site, manage the subs, keep the schedule tight, and make sure the work is right. We need someone who can own a commercial interior project from start to punch list — coordinate with owners, architects, and building officials, handle daily reporting in Viewpoint Team, and solve problems before they cost money. You lead by example and the people around you are better for it.

If you're just getting started:

We'll teach you. You'll shadow experienced supers, learn how to manage schedules and subs, run daily reports, and get hands-on with quality control and inspections. We're not looking for a finished product — we're looking for someone reliable, coachable, and hungry to learn the trade.

Either way, here's what matters to us:

→ Commercial interiors focus
→ Good communicator — jobsite to boardroom
→ Shows up, takes ownership, no ego
→ Valid MVR required at interview
→ Degree not required — what you've built matters more

What you get:

→ Weekly direct deposit
→ 401(k) with 6% match + annual profit sharing + bonus program
→ Company-paid health, dental, vision, short-term disability + $50K life policy
→ Vehicle allowance
→ 2+ weeks PTO, 10 paid holidays and sick pay
→ Real mentorship and a clear path to grow

We're a general contractor in Atlanta focused on commercial interiors. Good people, steady work, and a company that takes care of its own. If that sounds right, we'd like to meet you.
