REAL MODERN TERRAIN ARTS ANNOUNCES STRATEGIC CANCELLATION OF SUNNYSLOPE LOT DEVELOPMENT; PIVOTS FULL CAPACITY TO AUXBLOX™ BLOCK-LEVEL REDEVELOPMENT

PHOENIX, AZ — Real Modern Terrain Arts (RMTA) announced today that it will formally discontinue its planned development at the five-acre Sunnyslope hillside lot at 12th Street and Butler, concluding eighteen months of entitlement work, engineering analysis, and shifting federal support conditions that reshaped the project’s feasibility.

The passage of HB2999 earlier this summer opened a new federal pathway that eliminated the need for venture capital participation and the standard 51% ownership concession typical in early-stage land development. “One door after another opened for us,” said RMTA founder Ben Brosseau. “It became clear that Sunnyslope no longer aligned with the direction federal support was pushing us.”

Updated engineering reports showed that achieving Infrastructure Finance District (IFD) compliance would require scraping the entire shelf of the lot—break-up and removal excavation, cliff-side stabilization, and a dynamite-based demolition process involving insurance exposure tied to the neighboring Cliff Top House and its unresolved foundation issues. Civil analysis from CVL further reduced the feasible home count to eight units, forcing each homeowner to absorb a minimum $1 million land cost, most of it unbuildable view terrain.

“The moment the plan required us to do the opposite of what made it stand out, the decision became clear,” Brosseau said.

RMTA Redirects to AuxBlox™ Block-Level Redevelopment
With Sunnyslope formally closed, RMTA is redirecting its full development capacity toward AuxBlox™—the company’s modular, terrain-responsive block-level redevelopment system designed to scale across Phoenix and statewide. The same federal support unlocked by HB2999 now accelerates AuxBlox’s path forward.

AuxBlox was built for exactly the conditions Sunnyslope could never meet: predictable infrastructure, scalable entitlements, and a repeatable framework that strengthens neighborhoods instead of fighting terrain. The resources, engineering bandwidth, and ownership structure preserved by exiting Sunnyslope now move intact into AuxBlox, transforming what was once tied up in a single hillside experiment into fuel for a citywide system.

What AuxBlox™ Is
AuxBlox treats the interior of the city block—not the curb—as the primary terrain for new housing. Backyards, alleys, easements, and shared interior land become a coherent development surface, using existing utilities and avoiding the curb-side battles that slow traditional infill.

RMTA calls this think inside the block—a terrain-responsive pattern that uses what the city already has rather than forcing new infrastructure into places that don’t want it.

Why AuxBlox™ Matters
Phoenix has thousands of blocks with interior land geometrically perfect for modular housing but administratively invisible. AuxBlox makes that land legible, turning the back of the block into a development engine that doesn’t require demolition, street widening, or costly infrastructure spending. It is the opposite of hillside development: predictable, repeatable, economically rational.

How AuxBlox™ Works

• Block Mapping — Identifies blocks with depth, alley access, utility proximity, and parcel compatibility.
• Terrain Assembly — Homeowners opt in to contribute interior land segments, aggregated into a new development surface.
• Modular Placement — Architect-designed units positioned for privacy, solar gain, and alley-based access.
• Infrastructure Integration — Existing utilities tapped from alleys; no new trenching or street disruption.
• Neighborhood Continuity — Street frontage remains unchanged; neighborhoods retain identity while gaining new housing capacity.

A Pattern, Not a Product
AuxBlox is a repeatable geometry that works anywhere the block has depth. It builds inside the block, uses existing infrastructure, preserves neighborhood character, scales block by block, and aligns directly with federal support unlocked by HB2999. It is modular housing designed for the city’s actual terrain—not the terrain imagined by zoning maps.

RMTA will now concentrate on advancing AuxBlox across Phoenix, delivering architect-designed infill, predictable economics, and a model capable of transforming entire neighborhoods rather than a single hillside lot.
