Expanding a home through an accessory dwelling unit (ADU) or a full home extension requires careful planning, structural coordination, and precise construction methods. At Better Solution Painting, our ADUs and home extension services in Standish, ME are designed to create additional living space that integrates properly with the existing structure. Each project is completed with a focus on layout efficiency, material compatibility, and long-term durability.


Whether the goal is to add a separate living unit, expand a kitchen, or build additional rooms, the process involves multiple phases that must be executed in the correct sequence. From initial site preparation to final finishing, every step is handled with attention to detail to ensure the new space functions as part of the original home.

ADUs are self-contained living spaces that can be attached to or separate from the main home. These units require full construction processes, including structural framing, utilities, and interior finishes.

Accessory Dwelling Unit (ADU) Construction

Detached ADU Construction

Detached ADUs are built as separate structures on the property. Construction includes foundation work, framing, roofing, and complete interior installation to create an independent living space.

Attached ADU Integration

Attached ADUs are connected to the existing home and must align structurally and visually. This requires careful planning to ensure seamless transitions between the original structure and the new addition.

Utility and System Installation

ADUs require plumbing, electrical, and ventilation systems that function independently or connect to the main home. Proper installation ensures reliable operation and compliance with building requirements.

Home Extensions and Additions

Home extensions expand the footprint of an existing structure, adding new rooms or enlarging current spaces. These projects must be carefully integrated to maintain structural consistency.

  • Room Additions

    New rooms can be added to accommodate changing space requirements. Framing, insulation, and finishing are completed to match the existing home layout.

  • Structural Expansion

    Expanding a home involves modifying the existing structure to support additional space. This includes foundation extensions and reinforcement where necessary.

  • Roofline and Exterior Matching

    The roof and exterior finishes are extended to align with the current design. This ensures a consistent appearance across the entire property.

A stable foundation and properly installed framing are essential for any ADU or home extension. These elements provide the structural support for the entire project.

Foundation and Framing Work

Foundation Installation

Foundations are constructed to support the weight and layout of the new structure. Proper preparation ensures long-term stability.

Structural Framing

Framing defines the layout and supports walls, ceilings, and roofing systems. Accurate installation is critical for alignment and durability.

Load-Bearing Adjustments

When extending a home, load-bearing elements may need to be modified. These adjustments are completed to maintain structural integrity.

Interior Construction and Finishing

Interior construction transforms the structural framework into a functional living space. This phase includes walls, flooring, and all interior components.

  • Drywall and Wall Systems

    Drywall is installed to create smooth interior surfaces. Finishing ensures consistent coverage and clean transitions between areas.

  • Flooring Installation

    Flooring materials are installed based on the intended use of the space. Proper subfloor preparation ensures stability and longevity.

  • Cabinetry and Fixtures

    Cabinets, vanities, and fixtures are installed to complete kitchens, bathrooms, or living areas within the new space.

Windows and Doors

Windows and doors are installed to provide access, ventilation, and natural light. Placement is aligned with the overall design and layout.

Exterior Painting and Coatings

Exterior surfaces are painted or coated to ensure durability and a consistent finish. Materials are selected to withstand local weather conditions.

Project Coordination and Phased Construction

ADU and home extension projects involve multiple stages that must be coordinated effectively. Proper planning ensures that each phase is completed on schedule.

Site Preparation

The project begins with clearing and preparing the site for construction. This step ensures a stable starting point for foundation work.

Phased Construction Process

Work is completed in phases, including foundation, framing, utilities, and finishing. Each stage is inspected before moving forward.
