Additions, ADUs & Multi-Generational Spaces With Marnella
When we design and build an addition or ADU, we are careful not to “bolt on” a room. We look at your existing home, your site, and how the new space will be used, then shape a solution that integrates structure, style, comfort, and performance. That may mean a seamless primary suite on the main level, a light-filled family room that connects more closely to your yard, or a fully self-contained ADU with its own entry, kitchen, and bath. In every case, we pay attention to privacy, sound, and circulation, and we update the envelope and mechanical systems. Hence, the new area is as comfortable and efficient as the rest of the home. The result is extra space that feels intentional, not like an afterthought.
How the Process Works for Additions & ADUs
1. Site & Home Review
We start with a visit to understand your existing home, lot, and utilities. We talk about who will use the new space, how it should feel separate, and your long-term plans (family, work, rental, resale).
2. Concept Design & Feasibility
Next, we explore concepts: where the addition or ADU should go, how it connects (or intentionally separates) from the main house, and what is realistic within zoning, setbacks, and budget. We also look at structure, access, daylight, and parking where required.
3. Performance & Systems Planning
We then plan how the new space will be heated, cooled, and ventilated, and how it will tie into (or operate separately from) your existing systems. This step helps ensure comfort, efficiency, and good indoor air quality.
4. Detailed Scope, Pricing & Approvals
Once the concept and systems approach are straightforward, we finalize the scope, selections, and pricing. We prepare the drawings and documentation required for permits and approvals, and keep you informed of timelines and next steps.
5. Construction & Coordination
During construction, we work to limit disruption as much as the work allows, coordinate trades, and protect areas of the home that are not being touched. We schedule walkthroughs at key points so you can see progress and ask questions.
6. Completion, Orientation & Support
At the end, we walk you through the finished space, explain how everything works, and address any final details. Our warranty and aftercare support continue after move-in, whether the space is for family, guests, or tenants.

FAQs
How much does an addition or ADU usually cost?
Costs vary based on size, complexity, and whether it is attached or detached. We will discuss your budget early and then build a detailed scope and price so you know where you stand before committing.
How long does this type of project take?
Design, approvals, and permitting can take several weeks to a few months. Construction often takes a few months or more, depending on the scale. We will provide you with a project-specific timeline before work begins.
How disruptive will the work be to our daily lives?
There will be noise, dust, and some loss of access to parts of your home or yard while we build. We plan with you, protect unaffected areas, and keep you updated so you can work around key phases.
What do you handle and what don’t you do?
We manage design collaboration, structural and mechanical planning, permits, and complete construction of the addition or ADU. We generally do not take on tiny, stand-alone “shed” projects or cosmetic-only work that ignores structure and systems.
