What we do

Interior Design and Construction Under the Same Roof

Interior design at Sheiner Construction is the planning layer that makes construction work the first time.

Here's what most homeowners don't realize about interior design and remodeling: the two processes have to talk to each other constantly. Not after permits are submitted. Not when tile arrives on site. From the first session.

I'm Didi Sheiner. I work alongside Joseph Sheiner at Sheiner Construction, and I lead the design phase on projects where spatial planning, material selection, and finish specifications need to be locked in before construction begins.

When design and construction run under two separate agreements, decisions get made in the wrong order. A designer chooses a tile layout. A contractor reviews it after the shower niche is already framed. If the dimensions don't align, one of them has to move — and moving it costs money. Under our structure, I make design decisions and the construction team executes them. Same CSLB license (#1083621). Same project. No translation layer.

Sequencing

Materials Specified and Long-Lead Items Ordered — Then Permits Pull

Every finish decision has a deadline, and that deadline is earlier than most homeowners expect.

Local building departments — whether the City of San Diego's Development Services Department, San Diego County's Planning & Development Services, or municipal divisions in cities like El Cajon or Del Mar — need complete construction documents before a permit is issued. Those documents include plumbing rough-in locations, structural specifications, and fixture dimensions. That information comes directly from the design.

If the design isn't finished when permits are submitted, either the permit gets submitted with placeholder information that requires correction later — triggering a plan check cycle that adds weeks — or construction starts before the design is complete, and field decisions get made on the fly.

Material lead time is the piece that catches people off guard. Custom cabinetry from some manufacturers runs 10 to 14 weeks. Large-format porcelain tile from certain suppliers can be 6 to 8 weeks from a West Coast warehouse. If those items aren't ordered during the pre-permit design phase, they'll arrive after the framing inspection, and the crew waits. I identify long-lead items at the design stage.

Building codes and permit requirements are amended on a regular cycle. Confirm current requirements for your parcel with your local building department, or with the relevant authority, before relying on them for design decisions.

How a Design Session Becomes a Buildable Set

A homeowner in a La Jolla property wanted to reconfigure a primary bathroom and expand the closet into an adjoining room. Coastal San Diego properties like this one often have architectural constraints that aren't immediately visible — load-bearing walls in unexpected locations, exterior walls with fixed window configurations, concrete subfloors in certain areas.

Before I finalized a single layout option, I walked the space with Joseph. We confirmed which walls were structural, which weren't, where the plumbing stack ran, and what the existing electrical panel capacity was. Properties built in La Jolla in the mid-20th century sometimes have panels that need an upgrade before additional circuits are added. We knew that going in.

The design I produced was built around what the space could structurally support, not around what looked good on a rendering. The shower niche dimensions matched the tile format so there were no cuts at the perimeter. The vanity location accounted for the existing drain stub, which meant no horizontal drain relocation, no concrete saw, and no added cost.

When the permit documents went to the building department, every dimension, fixture location, and structural note was confirmed. The plan check came back clean. No correction cycle. See more of our projects.

Every material decision is confirmed against the structural and mechanical reality of the space. Nothing gets designed in isolation.

Buildability

Design Decisions That Are Buildable, Code-Compatible, and Confirmed

Every design I produce is checked against current California residential codes before it leaves the planning phase.

When design and construction operate under one agreement, every design decision is immediately tested against construction reality. If a recessed ceiling detail requires a structural header, I know before the drawing is finalized. If a new spatial layout needs to account for the 2026 California Title 24 energy mandates — such as heat pump integration or updated wall insulation requirements — it's built into the scope before permits are submitted.

The finish specification document — the documented list of every material, fixture, and finish with manufacturer, model, color, and dimensions — is complete before permits are submitted. Subcontractors receive exact specifications. No field substitutions.


Our standards

Our Interior Design and Construction Standards

Every design engagement at Sheiner Construction follows a documented pre-permit process.

Spatial planning first

Room layout, traffic flow, and storage decisions are finalized before materials are selected. These decisions affect structural requirements that can't be revised cheaply after permits are submitted.

Finish specification before permit submittal

Every material — tile, cabinet, fixture, countertop — is specified with manufacturer, model, color, and dimension before the permit application is assembled.

Long-lead item identification at design stage

Items with extended delivery timelines are ordered before permits pull so they arrive during construction, not after.

Code compatibility confirmed in design

Every layout decision is checked against current San Diego County and municipal building codes before documents are finalized.

Change order prevention by design

Most change orders originate from design choices deferred past the point of no return. We close that gap in the pre-permit phase.

One licensed agreement

Design and construction run under the same CSLB licence (#1083621), so there is no handoff between two contracts.


How the work runs

The Design-to-Build Execution Process

Three stages, each one closing before the next begins.

01

Site walk and structural assessment

Every design engagement starts with a site walk. I review the existing structure with the construction team — wall configurations, plumbing locations, electrical panel capacity, subfloor type, window placement. San Diego County homes vary considerably by neighborhood and decade. A North Park Craftsman from 1928 has a different structural profile than a 1970s ranch in Tierrasanta.

02

Design development and specification

Layout options are produced and reviewed against structural constraints. Once a layout is approved, finish specification begins. Every surface, fixture, and finish product is documented with full manufacturer information. This document becomes the basis for subcontractor bids and permit drawings simultaneously. Long-lead items are flagged and ordered at this stage.

03

Permit submission and construction handoff

Completed permit documents — incorporating all spatial decisions, structural notes, fixture locations, and material specifications — are submitted to the appropriate local building authority. Because the design is complete before submission, there's no placeholder information that requires a correction cycle. The space builds as designed.
