Design + Build

With 30+ years’ experience in real estate, design, and building, Riemco is equipped to be your partner at every stage of planning and execution. Every project reflects our deep commitment to environmental sustainability and “green building” practices that incorporate the best products, processes and technologies.

Smart Building

Because we are both builders and designers, we can seamlessly meld these two components to produce a home, remodel, or construction project that exceeds our client's’ expectations while staying within their budget. We pride ourselves on providing a high level of communication and transparency to every client from start to finish. We use decades of best practices combined with the latest building science, which results in durable, comfortable, and highly efficient structures. We have extensive experience with conventional framing, panelized systems (open wall and closed wall), ICF construction (Insulated Concrete Forms), and modular building systems.

Riemco's process aligns vision with reality

Whenever there is a disconnect between a designer’s vision and a builder’s realities, the client pays a price in either time, quality, or cost. Design + build is an alternative to the often-confusing process of hiring one company to design and plan a project and then seeking another company to interpret those plans and build it. With our single-source design + build system, the design process is constantly aligned with the realities of construction.

We begin with a thorough understanding of our client’s vision and an initial feasibility analysis of the project site. Design, the next step, takes that analysis and iterates the best solutions – with all vendors, construction professionals, the design team, and the client collaborating within an established budget. Final plans are fully detailed, and the project manager can then devote full energy to scheduling and technical problem-solving.

Feasibility: Remodel or build? Where do I start?

Likewise investors, prospective homeowners should look at many options and evaluate them against their wants, needs, timelines, priorities, and budgets. Riemco has the expertise to help you do this quickly and objectively within a preliminary budget framework.

Custom design work that seamlessly integrates with the building process

Riemco began as a building company and gradually began providing some of the design work for its homes. Initially, it was to fill in a gap: drawings brought to them by customers did not provide detailed specifications and customers often couldn’t visualize how the two-dimensional drawings would translate into finished work.

Over time, design work was fully integrated into our building business. Now our customers’ projects are modeled in virtual 3D using computer design software, enabling homeowners to better understand spatial relationships within the home and actively participate in making decisions that affect the final results, including cost.

We can modify and/or detail a plan from another source, or we can create an original plan based on your general ideas All design work done by Riemco is integral to its building process, rather than a stand-alone service.
