Project Overview: Legacy Layouts to Modern Compliance

Unified Studio Architect was brought in to develop a full architectural set—including precise foundation and elevation plans—for a residential property based on outdated and incomplete hand-drawn documents. The project required translating legacy records into fully dimensioned, code-aligned drawings that could support a building permit application.

This effort showcases our expertise in foundation plan architecture, where we move from conceptual or fragmented inputs into full architectural clarity ready for contractor execution, city plan review, and homeowner confidence.

Step 1: Analyzing Existing Conditions and Source Materials

The only source materials for this project were:

• Hand-drafted sketches with limited dimensions

• Faded, non-to-scale elevations

• Inconsistent annotations across pages

We began by assessing all existing artifacts and performed spatial cross-checking to:

• Identify key structural features: load-bearing walls, pier locations, and footprint outlines

• Establish floor-to-floor alignment and vertical consistency

• Determine accurate proportions based on field notes and site assumptions

This process formed the backbone of a new digital as-built model.

Step 2: Reconstructing the Foundation Plan for Engineering Coordination

Once we verified the base layout, we reconstructed a clear, annotated foundation plan to include:

• Footing Locations & Sizes: Continuous and spread footings with reinforcement specs

• Stem Walls and Piers: Height, width, spacing, and reinforcement shown

• Slab and Grade Beams: Thickness, control joints, and insulation requirements annotated

• Anchor Bolt Details: Spacing, embedment, and connection notes aligned with local seismic and wind loading codes

• Elevations and Step-Downs: Marked to indicate slope conditions and transitional grades

This foundation plan became the primary coordination document for the structural engineer and contractors.

Step 3: Full Floor Plan Redrafting with Dimensional Precision

We developed both first and second floor plans using the foundation layout as a structural base. Key highlights:

• Wall Placements: Interior partitions and exterior framing aligned with footing supports

• Room Dimensions: Scaled and dimensioned from framing edge to edge

• Openings and Fenestrations: Windows and doors located to match both architectural intent and structural feasibility

• Stair Integration: Stairwells dimensioned with riser/tread breakdown and headroom clearances

• Fixture Layouts: Bathrooms and kitchens laid out to support plumbing routing and user comfort

We ensured all clearances and circulation met International Residential Code (IRC) requirements.

Step 4: Developing Exterior Elevations for Design and Compliance

To complete the architectural picture, we produced four elevations:

• Front Elevation: Showing symmetry, trim work, window alignment, and porch features

• Rear Elevation: Included exit access, step-downs, and slope interface

• Left and Right Side Elevations: Showed vertical transitions, material joints, and window rhythms

Each elevation was drawn to scale with:

• Roof slopes and ridgeline heights

• Eave projections and gutter lines

• Trim types and siding breaks

• Window heights relative to finished floor

These elevations helped the client visualize the final build while satisfying city zoning aesthetics.

Step 5: Garage Foundation and Architecture

As the project included a detached garage structure, we developed a parallel architectural set featuring:

• Garage Foundation Plan: Footing layout, slab details, and stem wall notes

• Garage Floor Plan: Vehicle clearance, storage, and access stairs

• Garage Elevations: Roof pitch, door openings, venting, and siding treatments

• Garage Section View: Height clearances, framing assembly, and insulation locations

This ensured both functional utility and design consistency with the main house.

Deliverables: Complete, Permit-Ready Architecture Set

Unified Studio Architect delivered the following for permit submission:

• Digitally redrafted foundation plan architecture for both main house and garage

• Full as-built floor plans with wall, window, and plumbing layouts

• Front, rear, and side elevations drawn to scale with finish details

• A dedicated garage plan set with coordination across structural and aesthetic lines

• Annotation packages and dimensions suitable for engineers, builders, and plan reviewers

Results: Clarity, Compliance, and Construction Confidence

This project demonstrates how our foundation plan architecture process solves legacy challenges:

• Converting incomplete sketches into submission-ready plans

• Aligning building systems across floors and structures

• Documenting key elevation and structural details to satisfy code and contractors

The final drawing set allowed for:

• Smooth structural engineering collaboration

• Fast-track submission to city building departments

• Accurate cost estimating and builder mobilization
