When your home no longer fits the way you live, moving is not always the best answer. At RanDesign, we create custom home additions and custom ADU design solutions in Colorado Springs, CO, for homeowners who want more usable space without settling for a generic plan. Our work combines custom floor plans, residential drafting, construction drawings, site planning, and structural design knowledge to help turn an idea into something practical and buildable. With decades of local experience, we focus on creating additions and accessory dwelling units that fit the property, support long-term goals, and feel connected to the original home.
Custom Home Additions Designed Around the Way You Live
A good home addition should solve a real need, whether that means another bedroom, a larger living area, a home office, guest accommodations, or more room for a growing family. Simply adding square footage is not enough if the new space feels awkward or disconnected from the rest of the house.
Our home addition design process starts with how you want the finished space to function. We look at the existing layout, available property, circulation, architectural style, and long-term use before developing a custom solution around your priorities.
Making New Space Feel Like Part of the Original Home
One of the biggest challenges with residential additions is integrating the new construction with the existing structure. Rooflines, exterior proportions, interior transitions, window placement, and room flow all affect whether the addition feels cohesive or obviously added later.
We give those details careful attention during custom home addition design. Our goal is to create a home extension design that works structurally and visually, helping the expanded home feel intentional rather than patched together.
Custom ADU Design for Flexible Living
An accessory dwelling unit can add valuable flexibility to a property. Homeowners may consider an ADU for multigenerational living, guest accommodations, additional private space, or another residential use that benefits from separation from the main house.
We provide custom ADU design based on the individual property rather than forcing homeowners into one-size-fits-all plans. We consider placement, access, privacy, utilities, available space, and how the secondary dwelling relates to the primary home.
Attached and Detached ADU Design
Different properties call for different approaches. An attached ADU design may make sense when the homeowner wants direct connection to the existing residence, while a detached ADU design can create greater physical separation and privacy.
We evaluate the site and discuss how each option may affect layout, access, construction complexity, and overall use. Our job is to help determine what configuration makes the most sense before detailed ADU floor plans are developed.
Garage Conversion Design
An existing garage can sometimes offer another path toward additional living space. Garage conversion design requires more than drawing new interior walls because the structure, floor conditions, openings, insulation, utilities, and connection to the rest of the property all need to be considered.
We help homeowners explore whether a garage can realistically support the intended use. If the concept is workable, we develop custom floor plans and construction documentation around the actual conditions of the building.
Site Consultations Before the Drawings Begin
The property itself influences what can be built. Setbacks, grades, access, utilities, existing structures, and available yard area can all shape an addition or ADU before the floor plan is finalized.
Our site consultations help establish those realities early. We use space planning and existing-condition review to determine how the project can fit the property while supporting the homeowner’s goals and applicable building requirements.
Detailed Construction Drawings for a Buildable Project
Strong ideas need clear documentation if they are going to become successful construction projects. Contractors need drawings that communicate dimensions, layouts, structural intent, and important construction details accurately enough to price and build the work.
Our residential drafting and ADU construction drawings are developed with constructability in mind. We focus on creating detailed plans that give contractors useful information rather than leaving critical decisions unresolved until construction is already underway.
Structural Design for Home Additions
Home additions interact directly with existing foundations, framing, roofs, walls, and load paths. That makes structural planning an important part of the design process rather than something that should be considered only after the layout is complete.
We bring structural design knowledge into the planning of additions and expansions. This field-aware approach helps us think through how the proposed space connects to the existing house and where important construction considerations need to be addressed.
Custom Floor Plans Instead of Generic Templates
Every household uses space differently, which is why a stock floor plan rarely captures all the details that matter. A design should respond to the property, family routines, furniture needs, privacy preferences, and how the space may be used years from now.
Our custom floor plans are created specifically for the homeowner and site. Whether we are designing a bedroom addition, larger living area, office, or ADU, we build the plan around the project rather than asking the project to fit a template.
From Conception to Completion
RanDesign describes our role as being a resource from conception to completion, and that philosophy guides the way we work with homeowners. Early ideas often evolve as site conditions, priorities, budget considerations, and construction details become clearer.
We help guide the design process through those stages so clients have continuity instead of a disconnected series of decisions. One documented project included a remodel combined with an approximately 1,000-square-foot addition, demonstrating our experience with substantial residential expansion and integration.
What Our Addition and ADU Design Services Can Include
Our projects vary in scope, but the common thread is customized planning and detailed documentation. We help homeowners move from initial ideas toward construction-ready information through services such as:
- Custom home addition design
- Bedroom and living-space additions
- Custom ADU floor plans
- Attached and detached ADU design
- Garage conversion design
- Site consultations and space planning
- Residential drafting
- Construction drawings
- Structural design considerations
- Home remodeling and addition design
We tailor the scope to the project instead of assuming every client needs the same package. That keeps the design process focused on the work required to move the project forward effectively.

Frequently Asked Questions
How do I know whether an addition or ADU will work on my property?
A site consultation is the best starting point because property size, access, utilities, existing structures, and applicable requirements all affect feasibility. We review those conditions before developing detailed plans.
Can you design an ADU from scratch?
Yes. We create custom ADU floor plans around the property, intended use, and homeowner’s goals. We can design attached, detached, or qualifying garage-conversion configurations depending on the site.
Do you provide construction drawings for contractors?
Yes. We prepare detailed construction drawings intended to give contractors clear, buildable documentation. The exact drawing set depends on project scope and applicable requirements.
Can you make an addition match my existing house?
Yes. Existing-home integration is a central part of our design approach. We consider architecture, rooflines, layout, transitions, and proportions so the addition feels cohesive with the original structure.
Do you offer free estimates or consultations?
Yes. RanDesign offers free estimates, and consultations can be scheduled to discuss project goals and next steps. Weekend appointments are available by arrangement.
