One Team. One Contract.
One Company Handles Your Design, Permits, and Construction
David Zivyon and Rotem Zivyon co-own and lead RT Signature Homes. They founded the company in 2015 around a single operational principle: the same team that develops your floor plan pulls the permits and builds the project.
That means no gap between what was drawn and what gets built, and no homeowner managing handoffs between an architect, a permit expediter, and a general contractor.
To understand how design-build compares to hiring a general contractor, the difference comes down to accountability: one team owns the outcome from design through construction.
The result is a project that moves on a defined timeline, with one point of contact, seven dedicated in-house project managers, and a ten-person team that handles the full scope from structural design through finish installation.
Local Experience
Built for Seattle's Construction Environment
Seattle's residential construction conditions are specific, and a home remodeling contractor working here needs to know the difference.
RT Signature Homes operates from its office at 4164 148th Ave NE in Redmond, positioned within the SR-520 corridor, twelve miles from most Seattle project sites, and within direct reach of Bellevue, Kirkland, Sammamish, and Bothell.
Project managers run same-week site assessments without the scheduling delays that push start dates back by weeks.

The first site visit almost never confirms what a homeowner assumed before we arrived.
A Kirkland homeowner measured their rear yard on a parcel map and figured they had room for an ADU. On the lot, a mature cedar sat where the DADU needed to go, the rear setback took another five feet, and the utilities were on the far side of the house. None of it showed up in the parcel data.
We moved the ADU to a spot that cleared the tree, held the setbacks, and sat near the existing utilities. The permit came back clean. That's the work — the decisions before the drawings. All seven of our project managers do it before scope is written.
You design around what the site is.

Our Standards
Consistent Standards Across Every Project
Every RT Signature Homes project follows the same process and material standards, regardless of project size.
All permit applications filed in-house by the assigned project manager, no permit-expediting service. See the Seattle remodeling permit process explained.
Material selections confirmed against 2021 WSEC prescriptive requirements before orders are placed.
Structural conditions verified by in-house project managers before demolition begins.
Board type, waterproofing membrane, and drainage grade confirmed against code and site conditions before installation.
Subcontractor scheduling coordinated by the project manager, no homeowner managing trade sequencing.
Final inspection attended by the assigned project manager, no handoff to a closing crew.
Seven project managers. Ten employees. All operating from the Redmond office. No scope is passed to a third-party project-management layer, the project manager assigned at the first site visit is the same person at the final walkthrough.
How It Works
How a Project Works With RT Signature Homes
One team, one contract, from the first site visit through the certificate of occupancy.
Diagnostics & Site Assessment
Every project starts with a site visit. The assigned project manager walks the lot or existing structure, measuring setbacks, confirming lot coverage, checking structural conditions and mechanical systems. No design work begins until site conditions are confirmed.
For ADUs that means setbacks, lot coverage, utility points, and soil. For interior remodels it means load-bearing walls, plumbing rough-in, and panel capacity, so design reflects what the permit office will approve, not what a generic layout assumes.
Design, Permitting & Pre-Construction
The design phase begins with construction input built in from the first session. Permit drawings are produced by the same team that will build the project, and material selections are made after structural constraints are confirmed, not before.
Applications are filed directly with the applicable jurisdiction: Seattle DCI for city properties, Bellevue Development Services, or Redmond's permit office. You receive a timeline that accounts for the permit review period.
Construction, Inspection & Final Walkthrough
Construction is sequenced by the assigned project manager, framing, then rough mechanical, then insulation and drywall, then finishes. Each inspection stage is scheduled and attended by that same manager.
Final inspection is conducted against the approved permit drawings, and the certificate of occupancy is issued after sign-off. You receive a completed project with a full permit close-out, not an open permit that resurfaces at the next real-estate transaction.
