Home Addition Contractor in Philadelphia
Expand your home with additional living space designed around your existing property and how you want to use it.
More Space Without Leaving Home
When your existing home no longer provides the space you need, an addition can create new possibilities without requiring you to move.
BC Property Development coordinates residential addition projects for Philadelphia-area homeowners, bringing together the structural work, construction phases, and improvements required to connect new space with the existing home.

Existing Home Expansions

An Addition Has to Work With the Existing Home
A home addition isn't a separate structure simply attached to the house. New construction needs to work with the existing building, including its layout, structure, utilities, exterior conditions, and how people move between the old and new spaces.
Planning that connection carefully helps the addition feel like part of the home rather than an afterthought.

Structural Planning for Home Additions
Adding new space can affect existing walls, framing, foundations, openings, and other structural components of the home. The conditions of the existing property need to be understood before construction moves forward.
Depending on the project, structural engineering, plans, permits, or other professional documentation may be required.
Home Additions in Philadelphia
Adding space to a Philadelphia home can present different challenges than building on an open suburban property. Existing rowhomes, masonry construction, neighboring properties, lot dimensions, zoning requirements, and the condition of the existing structure can all influence what is possible.
The appropriate approach depends on the individual property and the type of addition being considered. BC Property Development works across the Philadelphia service area and can discuss the construction aspects of a potential project.
Planning, Zoning & Permits
Home additions can involve zoning, building permits, construction plans, and other approvals depending on the property and proposed work. These requirements should be understood before construction begins.
Because every property and project is different, the approvals required for an addition depend on the specific scope and location.
Our Home Addition Process
Discuss Your Goals
Tell us why you need additional space, how you want to use it, and what you're considering for the property.
Review the Existing Property
We review the existing home and conditions relevant to the proposed construction.
Define the Project Scope
The addition is organized around the proposed space, existing structure, construction requirements, and applicable plans or approvals.
Coordinate Construction
BC Property Development manages the construction process and coordinates the different phases required to integrate the new space with the existing home.
Complete the Addition
The project progresses through construction and finish work toward completion of the agreed scope.
Renovating While You Add Space
An addition can also be an opportunity to improve the existing areas it connects to. For example, expanding a kitchen may involve renovating the original kitchen, while adding living space may require changes to adjoining rooms or circulation through the home.
BC Property Development can coordinate renovation work alongside the addition when it is part of the broader project scope.
One Contractor for a Multi-Phase Project
Home additions involve multiple phases of construction that need to work together. BC Property Development provides general contracting services to coordinate the overall construction scope and the different areas of work involved.
