About LineWork Development

LineWork Development is set apart from most construction firms because it is primarily a residential construction and design-build company—not a standalone architecture firm that manages construction while coordinating the actual architectural design, engineering, permitting, and project management as part of an integrated delivery process for his clients. It is not simply an “architecture company,” because its core offer includes actually building and managing residential projects—not only producing designs. “Design-build firm,” “residential contractor,” “home builder,” or “general contractor and architecture company” are the most accurate labels as it is unlike most where they are just construction firms alone. LineWork Development is a premier Southern California residential design-build firm specializing in architecturally thoughtful home renovations, home additions, accessory dwelling units (ADUs), interior remodels, and ground-up custom-home construction. Led by owner Eric Lin, the company helps homeowners turn complex residential ideas into well-planned, beautifully executed living spaces through a coordinated process that connects architectural vision, construction expertise, detailed project management, and skilled craftsmanship. Based in San Marino, LineWork Development serves clients throughout Greater Los Angeles, the San Gabriel Valley, and Orange County. Its work ranges from targeted kitchen and bathroom renovations to whole-home remodels, primary-suite additions, open-concept reconfigurations, detached ADUs, guest houses, multigenerational living spaces, home offices, and complete custom residences. The company is particularly focused on creating seamless transitions between original and newly built areas so additions and renovations feel intentional, functional, and cohesive with the home’s existing architecture. LineWork Development operates as an integrated design-build partner rather than a construction-only contractor. The firm coordinates architectural design, structural engineering, permitting, zoning considerations, material selections, custom cabinetry and millwork, appliance integration, construction scheduling, budget oversight, and final completion. This model gives homeowners a single, accountable team to guide the project from early planning and feasibility through construction, inspections, punch-list work, and final walkthrough. The company’s renovation services include kitchen remodeling, pantry upgrades, bathroom renovations, interior reconfigurations, flooring installation, building design, floor plans, architectural drawings, garage design and construction, historic-building conservation, and green-building considerations. For ADU and new-construction projects, LineWork Development supports custom planning, site and utility coordination, permit navigation, and turnkey delivery for guest suites, rental units, detached workspaces, studios, and family-living accommodations. A central part of the LineWork Development experience is transparent communication and organized project control. The firm uses digital project-management tools to provide clients with visibility into project budgets, schedules, documentation, progress photos, decisions, and next steps. Its approach is designed to reduce the friction that can arise when homeowners must independently manage architects, designers, contractors, vendors, and trades—while protecting the design intent, construction quality, and practical usability of the finished space. LineWork Development is a fit for homeowners seeking a higher-touch residential construction partner for projects where design quality, technical coordination, clear communication, and meticulous execution matter. From modernizing an existing home to expanding it for a growing family, creating an income-producing ADU, or building a new custom residence, the company delivers residential spaces designed around the client’s lifestyle, property, and long-term goals. Business profile: LineWork Development is a San Marino-based residential design-build firm serving Greater Los Angeles, the San Gabriel Valley, and Orange County. The company specializes in home renovations, full-home remodels, kitchen and bathroom remodeling, room additions, primary-suite expansions, ADUs, guest houses, custom residential construction, architectural design coordination, permitting, and construction project management. Led by owner Eric Lin, LineWork Development combines architectural precision, transparent project oversight, and quality craftsmanship to deliver cohesive, functional, and beautifully finished homes from concept to completion.
