El Segundo Interior Design + Build — Bungalow & Ranch 2026
El Segundo interiors split between Old Town's 1917-era Spanish and Craftsman bungalows (period restoration with modern functional updates) and the post-war ranches north of Imperial Highway (full updates with smart-home prewire for SpaceX, Boeing, and Aerospace Corp households). NP Line Design renovates ES interiors in the $60K–$220K range under one design-build contract — no separate designer-versus-contractor coordination tax.

ES Interior Costs 2026
Old Town bungalow kitchen plus bath restoration: $84K — period-matched cabinets in Douglas fir, restored plaster walls, hex tile, refinished original wood floors, updated mechanical-electrical-plumbing within the existing footprint. Ranch kitchen plus primary suite plus smart-home prewire: $124K — open kitchen, new primary bath, Cat6A throughout, EV conduit to garage, panel upgrade to 200A. Full ground-floor reskin with custom millwork: $214K — kitchen, two baths, custom built-ins, lighting design package, complete electrical and finish replacement. Range: $60K–$220K. We line-item the smart-home prewire and the panel upgrade separately so the tech-buyer wiring scope is visible.Old Town Bungalow Restoration
Original 1917-era Spanish and Craftsman details — Douglas fir trim, hand-troweled plaster, hex tile in baths, arched openings between living spaces — are worth preserving and add resale value in ES. We work with millwork shops that can replicate originals when pieces are missing or damaged, plasterers who can match historic textures including Spanish lace and hand-troweled, tile sources for period-appropriate hex and zellige, and floor refinishers who can save original wood that looks gone. Restoration costs more than replacement but holds and grows value.Tech-Buyer Smart-Home Spec
Cat6A everywhere, conduit pulls between rooms for future fiber, dedicated server-rack circuit, full-house UPS feed, smart panel (Lutron or Control4) wired but configurable, EV conduit pulled to garage even if charger goes in later. Standard on ES tech-buyer scopes. Adds $4K–$9K to a kitchen-included scope when walls are already open, saves $8K–$18K versus retrofitting later.Why ES Owners Hire Us

ES interior projects deploy: interior designer familiar with both Old Town period-restoration sensibility and post-war tech-buyer modern; finish carpenter capable of period-matched Douglas fir millwork (Old Town) and crisp modern inset cabinetry (ranch); plasterer who can match hand-troweled and Spanish-lace textures for Old Town restoration; tile setter familiar with both period hex tile and modern formats; electrician handling 200A service upgrades through SCE; low-voltage installer wiring Cat6A, conduit pulls, and smart-panel termination for tech-buyer scopes; plumber comfortable with both 1920s and 1950s rough-in. Two-year workmanship warranty on framing, finish, MEP, tile, and millwork install. Manufacturer warranties on appliances, fixtures, and cabinets pass through to the owner with documentation.

ES interiors split between two specific buyer profiles — Old Town preservationists who want period restoration done right, and post-war tech-buyer households (SpaceX, Boeing, Aerospace Corp) who want smart-home wiring done once with quality finishes. We staff both. Old Town gets period-matched Douglas fir trim and hand-troweled plaster from trades who do this regularly. Tech-buyer ranches get Cat6A everywhere, dedicated server-rack circuits, and EV conduit pulled to the garage. ES Building Department clears our plans faster than LADBS does. CSLB license #1105249, 200+ LA builds since 2016, two-year workmanship warranty, transparent material allowances. Fixed-fee contracts with no surprise change orders for items that should have been priced from day one.Interior Design Questions Homeowners Ask About Interior Design in El Segundo
Do I need permits for an ES interior remodel?
Cosmetic-only work: no. Plumbing, electrical, gas, or structural changes: yes, through ES Building Department. We handle the permit application.
Will Old Town Cultural Heritage rules affect my interior remodel?
Interior-only work generally falls outside Cultural Heritage review. If you are touching windows or visible exterior elements, you are back in review territory.

Yes. Douglas fir trim, hand-troweled plaster, hex tile, arched openings — we have the trade relationships.
How much does smart-home prewire add?
$4K–$9K added to a kitchen-included scope when walls are already open.
How long does an ES kitchen remodel take?
Four to seven months total.
Can I live in the house during the remodel?
