Custom Kitchen Islands & Peninsula Additions in Sussex County, NJ

A custom kitchen island or peninsula is one of the most impactful upgrades you can make to your home. It adds prep space, storage, and seating — and it transforms how your kitchen functions day to day. We design and build each island and peninsula from scratch, tailored specifically to your kitchen's layout and your family's needs.

Custom Islands vs. Peninsulas — Which Is Right for Your Kitchen?

A kitchen island is a freestanding unit positioned in the center of your kitchen, accessible from all four sides. It works best in larger, open-concept kitchens where there's adequate clearance for movement and workflow. An island can incorporate storage, seating, a prep sink, or additional appliances.

A peninsula is a connected extension of your existing cabinetry or countertop, attached to a wall or cabinet run on one end. It's an excellent solution for mid-sized kitchens where a freestanding island isn't practical — providing many of the same functional benefits with a more space-efficient footprint.

During your free in-home consultation, we'll evaluate your kitchen's dimensions, traffic flow, and your priorities to recommend the right solution for your space.

Custom Island & Peninsula Features

Every island and peninsula we build is designed around your specific kitchen and lifestyle. Options and features can include:

  • 1 Custom cabinetry and drawer storage built into the island base
  • 2 Integrated seating overhangs for bar stools or bench seating
  • 3 Built-in wine storage, pull-out shelving, or open display shelves
  • 4 Prep sink cutout and plumbing coordination
  • 5 Mixed materials — hardwood bases with waterfall countertops, butcher block, or stone
  • 6 Panel-ready appliance integration
  • 7 Contrasting finishes to create a focal point in the kitchen

Not sure if refacing or full replacement is right for you? We'll assess your cabinets in person and give you an honest recommendation — free of charge.

Our Kitchen Island & Peninsula Process

We begin with a detailed in-home consultation to assess your kitchen's layout, measure the available space, and discuss how you use your kitchen every day. This conversation drives every design decision — from the size and shape of the island to the storage configuration and finish.

From there, we develop your design concept, including a layout drawing that shows how the new piece integrates with your existing kitchen. Once the design is approved, we fabricate every component in our shop and install it on-site with full attention to level, alignment, and finish quality.

We coordinate with countertop fabricators and, if needed, plumbers and electricians to ensure a seamless finished result. The project is complete when every drawer opens smoothly, every panel is flush, and the new island or peninsula looks like it was always part of the space.

Kitchen Islands as Part of a Larger Renovation

A kitchen island or peninsula addition pairs naturally with other renovations — new cabinetry, cabinet refacing, countertop replacements, or a full kitchen remodel. We often incorporate island and peninsula additions into broader kitchen renovation projects, ensuring a cohesive design from cabinetry to countertop.

If you're considering a larger kitchen update, adding an island at the same time is typically more efficient and cost-effective than returning for a second project later.
