Turn the home you have into the home you want.

Architectural planning for renovations and additions—combining space planning, sketching, client options, construction drawings and practical construction experience.

Licensed ArchitectConstruction Management ExperienceLocal Residential Focus
Professional Guidance

Start with what is possible—and what is reasonable.

Greg Nowell helps homeowners make informed choices before and during renovation, from early property and zoning questions through design, permitting and construction coordination.

The goal is to clarify the opportunity, test options visually, and give owners useful information for working with designers, contractors and building departments.

Inspection & Property Evaluation

Understand existing conditions, constraints and opportunities before committing to a project.

Zoning & Feasibility

Explore additions, usable square footage, setbacks and realistic ways to expand.

Design & Space Planning

Compare layouts, circulation strategies and alternatives for kitchens, baths, additions and living spaces.

Construction Documents

Translate the selected design into drawings that communicate dimensions, materials and construction intent.

Permitting & Coordination

Support the permitting process and communication with contractors and building departments.

Contracts & Construction Management

Owner-focused guidance through pricing, contractor coordination and construction decisions.

Selected Work

Breadth of design—from first sketch to finished space.

These examples are organized to show the full range of residential design thinking: existing-condition analysis, options, hand sketching, rendered plans, visualization, working drawings and completed work.

Design Approach

Make the decision visible before you build it.

Good renovation planning is not one drawing. It is a sequence of increasingly specific decisions that let the homeowner understand consequences before construction begins.

01

Understand the existing house

Document the rooms, structure, circulation, zoning constraints and what is—and is not—working today.

02

Test more than one idea

Use sketches and plan options to compare possibilities, priorities, tradeoffs and cost implications.

03

Develop a buildable solution

Carry the preferred concept into coordinated plans, elevations, details, permitting and contractor communication.

Client Options

Compare alternatives, not just drawings.

Rendered plan options give homeowners a clear way to compare cabinet layouts, islands, circulation and room relationships. The drawings become a decision-making tool—not merely a technical product.

Sketching

Three-dimensional thinking from the beginning.

Hand sketching is a fast, direct way to explore massing, proportion and character. It helps the homeowner see the idea as a place rather than trying to interpret plan lines alone.

Design Development

From concept to coordinated architectural information.

The Beyrer Residence example brings together plans, elevations and perspective views to show how a residential addition is developed as a complete design—not simply as an isolated room.

Designing for today—and for tomorrow.

The Stanford bathroom shows how accessibility can be integrated into a clean residential design. The open, zero-threshold shower supports aging in place while maintaining a calm, finished appearance.

Thinking about changing your home?
