Completed Villa Park luxury residence at dusk, built by Newport Construction Group

Most of what makes a home like this possible is invisible by the time you walk through the door. This is the full story of one build, every phase in the order it happened, because the engineering, coordination, and inspections beneath the finishes are exactly what separate a custom residence that lasts from one that merely looks the part.

Newport Construction Group managed the entire process: design coordination, procurement, structural framing, every trade, and every City inspection, through to the finished pool and landscape.

Phase 01

Planning, scheduling & procurement

A house this size is not built by moving from one task to the next and hoping the materials show up. Before anything came out of the ground, the whole job was laid out in a Microsoft Project schedule that tied together construction, procurement, fabrication, inspections, owner selections, and the long-lead items that decide a completion date.

Windows, entrance doors, cabinetry, plumbing fixtures, flooring, stair components, structural steel, PSL members, and Simpson Strong-Walls all carry weeks or months of lead time. Each was identified early and ordered against the schedule, so the crews never stood waiting on a delivery and the trades never collided. The schedule was the backbone of the entire build — the tool that protected the finish date and kept hundreds of separate activities in sequence.

Project & Construction Management

Even when an owner has already chosen their own architect, engineers, and subcontractors, someone still has to control the schedule, procurement, sequencing, and coordination that hold a complex project together. Newport Construction Group provides that management as a standalone service: the master schedule, long-lead tracking, inspection sequencing, and field coordination that keep a major build on course.

Phase 02

Asbestos abatement

The lot already held an older home, and older homes hide older materials. Before any demolition, the existing structure was tested for asbestos and lead paint, and the regulated materials were removed under full containment, with sealed work areas, negative-pressure HEPA filtration, and licensed abatement crews all in place before a single wall came down.

It is the least glamorous phase of the project and one of the most important. Done properly, it protects everyone on site and every neighbor around it, and it clears the way for demolition with the paperwork to prove the site is safe.

Regulatory detail

All abatement complied with OSHA 29 CFR 1926.1101 (asbestos) and 1926.62 (lead), and EPA 40 CFR Part 61 Subpart M (Asbestos NESHAP) and Part 745 Subpart E (Lead RRP). Regulated work areas, containment barriers, warning signage, dust controls, and worker protection were established; materials were wetted, sealed, labeled, and disposed of at an authorized facility, with air-clearance testing and disposal manifests completed before construction continued.

Phase 03

Site survey, grading & engineered fill

With the existing ~2,500 SF residence demolished, a licensed surveyor mapped the lot, capturing property lines, existing grades, street elevations, utilities, and drainage, and handed that to the civil and geotechnical engineers. The site sat roughly 20 inches below the street, so the pad had to be built up, not just leveled.

Inside the footprint and four feet beyond it, the ground was over-excavated about four feet, moisture-conditioned, and rebuilt with engineered fill placed in controlled lifts and compacted to at least 90%, until the finished pad sat about a foot above street level. Everything the house would later stand on was verified and certified before a footing was dug.

Over-excavation ran ~4 ft below existing grade across the footprint plus a 4-ft perimeter. Engineered fill was placed in lifts not exceeding 18 inches and compacted to a minimum 90% relative compaction per ASTM D1557, with compaction testing throughout and final grading certification submitted before foundation construction.

Phase 04

Subsurface stormwater system

Water is what quietly destroys hillside and pad-built homes, so drainage was engineered rather than improvised. At the rear of the lot, three 36-inch perforated pipes were buried with filter fabric and drainage rock, tied into a reinforced-concrete storage vault sized to catch overflow when the system fills during a storm.

A duplex pump system with high-water alarms moves water out through a discharge line that runs roughly 118 feet to the street. Every slope, elevation, and pump capacity was set by the civil and geotechnical engineers and inspected before it disappeared underground.

Phase 05

Design, structural engineering & permits

Working from the survey, grading plans, and geotechnical report, the architect developed two design directions for the owner to choose between. Once the direction was set, the full package was coordinated into one construction-document set: architectural, structural, civil, grading, drainage, mechanical, electrical, plumbing, and Title 24 energy.

The structural engineer produced the foundation and framing plans, shear-wall and hold-down requirements, beam and connection details, and Strong-Wall layouts. The team resolved conflicts between architecture and structure before submittal, then carried the plans through City plan-check and every round of corrections until the permit was issued. Nothing was built until the stamped plans were approved.

Phase 06

Foundation: layout, underground & pre-pour

With the permit in hand, the building was laid out on the pad, with footprint, control lines, elevations, and every setback verified before excavation. Footings were dug, forms were set, and the underground plumbing went in and was pressure-tested before any steel covered it.

Then came the reinforcing: rebar, dowels, anchor bolts, hold-down assemblies, and Strong-Wall templates positioned exactly to the engineer's details, plus a code-required grounding electrode built into the footing. A sand-and-vapor-barrier bed went under the slab, the slab grid was tied, and only after the City signed off every concealed component was the foundation cleared to pour.

What went in before the concrete

A concrete-encased Ufer ground used a 20-ft continuous run of 5/8" reinforcing steel per NEC 250.52(A)(3), plus a 10-ft, 5/8" copper-clad driven rod and bonding per NEC Article 250. The slab bed was 2" sand, a 10-mil polyethylene vapor retarder with sealed laps, and a second 2" sand layer. City foundation, reinforcing-steel, underground-plumbing, grounding, and pre-pour inspections were all completed and signed before placement.

Phase 07

Concrete placement, finishing & curing

Pour day is one of the few milestones you cannot redo. The pump and crew arrived about two hours ahead of the first truck to set up and prime, and placement started early to beat the afternoon heat. A crew of roughly eight finishers, two laborers, and the pump team kept the concrete moving continuously so the whole foundation set as one piece, with no cold joints.

Concrete was vibrated around the steel and hardware, screeded and power-troweled to a flat, dense finish, then cured under controlled moisture. Rushing any part of this shows up years later, so it was not rushed.

Placement & curing detail

Mix design, compressive strength, slump, and truck intervals were confirmed with the batch plant before the pour. A backup vibrator stood ready on site. Finished-floor elevations and flatness were monitored throughout, and curing followed ACI PRC-308 guidance. Forms were stripped only once the concrete had gained enough strength, then exposed surfaces were inspected and cured further.

Phase 08

Structural framing & engineering

This was the most demanding phase of the build. The design called for large open rooms, tall ceilings, wide spans, and a dramatic foyer tower — exactly the conditions that leave little ordinary wall to carry the house. So the structure went well past conventional framing: PSL parallel-strand beams and columns, wide-span structural steel, engineered headers, and multiple Simpson Strong-Wall systems, all tied into a continuous load path from the roof down into the foundation.

Every beam, post, strap, and hold-down did a specific job in that load path, and none of it could be cut, drilled, or moved in the field to make room for another trade. The whole system rested on about 138 pages of structural calculations and the City-approved drawings. Small errors low in the structure multiply as they climb, so the foyer tower and tall walls were checked for dimension and alignment at every level.

When framing was complete, the Structural Engineer of Record walked the building in person and confirmed it matched the approved design before the City framing inspection, a last look at the skeleton before insulation and drywall hid it for good. That City sign-off was one of the biggest milestones of the whole project.

Phase 09

Concurrent MEP rough-in

A build this size can't run in a straight line. As soon as the first floor was framed and safe to work in, the mechanical, electrical, plumbing, and fire-sprinkler crews started their rough-in there while framing continued above. The trades followed the framers through the house instead of waiting for them to finish.

The rule that governed all of it: structure comes first. No trade cut, drilled, or notched a PSL beam, steel member, or Strong-Wall to make room for a pipe or duct. Where a route conflicted with the structure, it was reviewed and rerouted to protect the engineered load path and avoid expensive rework, so framing and concealed systems reached inspection together, ready for insulation and drywall.

Phase 10

Enclosure: stucco, foam molding & drywall

With the structure approved, the house was closed in. Windows and doors were set and flashed into a continuous drainage plane, the walls were wrapped and lathed, and the exterior was finished in a traditional three-coat stucco system of scratch, brown, and finish, with a City inspection before each layer was buried.

Then the detail that gives the house its face: roughly $85,000 of custom architectural foam molding across all four elevations, the bands, cornices, columns, and window surrounds that create the shadow lines and proportion people actually notice. Inside, the framing was hand-planed straight before insulation, the cavities were insulated and inspected, drywall was hung and fastener-inspected, and both staircases, including the large circular stair, were installed as the house moved toward finishes.

Why the molding mattered

The foam molding was treated as part of the architecture, not an add-on: profiles were sized, aligned, and proportioned against windows, arches, columns, rooflines, and viewing angles around all four sides. Applied well, it reads as though it always belonged to the building — and it is one of the first and most lasting things anyone sees.

Phase 11

Interior finishes & completion

This is where months of concealed work turned into rooms. Custom kitchen cabinetry, designed and fabricated months earlier against the schedule, was set level and true, followed by bathroom vanities, His-and-Her walk-in closets built as finished rooms, stone and tile, and countertops templated to the installed cabinets.

Then the trades returned in sequence: finish plumbing and the tankless hot-water system, lighting and the chandeliers sized to the foyer's height, flooring, interior doors and trim, stair railings, and paint over surfaces prepared so the final coat could look effortless. A room-by-room punch list closed out the details. Every visible finish rests on the precision of the structure beneath it.

Phase 12

Pool, decking & outdoor living

The backyard was designed as an extension of the house, not a leftover. Directly outside the rear sliding doors, a broad deck steps down toward a long, softly curved swimming pool, a lawn, and planted beds — one connected environment rather than separate features.

The pool went in as a full system: reinforced shell, circulation, filtration, heating, bonding, and lighting, with the equipment tucked away for easy service. A curved built-in seating area breaks the deck into gathering spaces, and every elevation was set so water always runs away from the house, from door thresholds and deck to coping, poolside paving, and drainage. Open the rear doors and the living areas simply continue outside.

The completed residence

Built to last, from the skeleton out

From an older 2,500 SF home on a below-street lot to a ~7,000 SF custom residence with a curved pool and gardens — engineered on paper, built in the field, and inspected at every step. If you are planning a custom home, addition, or complex structural project in Orange County, this is the level of control we bring to it.
