About 3135 11th St
This is a distinct custom home in Boulder’s coveted Newlands neighborhood, built for sophisticated everyday living and memorable entertaining. At approximately 6,187 finished square feet, the contemporary design showcases Brazilian teak floors, knotty alder millwork, vaulted ceilings and skylights that open rooms to the foothill outlooks. The gourmet-inspired kitchen features double ovens, a gas range and a butler’s pantry that flows directly to formal dining and informal gathering areas. A private studio with half bath on the main level is ideal for an art practice, guest quarters or a private office.
The primary suite is a retreat: a private deck with foothill views, a gas fireplace and a spa-style bath with jetted tub, steam shower and custom closet. An upstairs sun-room captures mountain vistas and there is a second guest suite with en-suite bath and private laundry for visitors or family. The family room’s stone gas fireplace and antique barn-timber mantel create an inviting center for evenings at home.
The lower level is purpose-built for media and multi-generational living — two guest suites share a Jack-and-Jill bath, and the expansive rec/media room includes a wet bar, mini-fridge, fireplace, built-ins and a drop-down movie screen. With a private entrance this floor can serve as in-law space or flexible rental. Practical systems include whole-house solar, backup generator, radiant zoned heat, whole-house water and air purification, two sump pumps and a swamp cooler for dry-season comfort.
Outside, a trellised patio, custom gas firepit, greenhouse and raised garden boxes create a private yard oasis. The oversized heated two-car garage and ample storage finish the package. Located minutes from Pearl Street, Chautauqua trailheads and the University of Colorado, this property delivers a unique blend of luxury, efficiency and outdoor access — schedule a private showing to experience the detail and flow in person.

Neighborhood & Location
Newlands is a mature, close-in Boulder neighborhood prized for its tree-lined streets, proximity to downtown Pearl Street and immediate access to foothill trailheads. Houses here range from classic Boulder cottages to large custom contemporary homes. Residents enjoy neighborhood walkability, strong school options and easy access to dining, shopping and open space.
Market Insights
Newlands remains one of Boulder’s most consistent premium neighborhoods: close-in to downtown while directly bordering foothill open space. The local market balances strong demand for turnkey, move-in-ready homes with selective activity in the luxury tier. Median sale prices citywide are well below this property’s tier, but the premium for location, size and systems (solar, generator, radiant heat) sustains buyer interest. Inventory in Boulder has been tight historically, with seasonal increases in spring and summer; high-end homes ($3M+) typically experience longer marketing timelines and more negotiation. For sellers: emphasize systems documentation, staging for indoor-outdoor spaces and targeted outreach to relocating executives and university-affiliated buyers. For buyers: value is driven by the finished lower level, efficiency systems and direct access to trailheads. Confirm comps through IRES/MLS; expect competitive showings if priced within the local luxury band.

Key Findings
- Active list price: $3,895,000 (MLS #1053294).
- Gross building area: 6,187 SF; Lot: 9,583 SF (approx. 0.22 acres).
- 5 bedrooms, 5 bathrooms; built in 2005; contemporary style with custom finishes.
- High-end systems in place (solar, generator, radiant heat) reduce immediate capital needs.
- Property has a history of multiple listings and price adjustments since 2023; current pricing positions it competitively within the high-end Newlands market.
Things to Consider
- Luxury price point increases marketing time and can require price flexibility in a cooling national market.
- Solar and generator equipment ownership/agreements should be verified; replacement/maintenance costs for custom finishes can be elevated.
- Potential ADU/land-use restrictions if buyer seeks to convert spaces to separate units — verify with City of Boulder.
Opportunity Analysis
Position the home to attract executive families and buyers relocating to Boulder who value proximity to downtown and outdoor access, emphasizing turnkey systems and flexible finished lower level for in-law or rental income. Price competitively within the $3.5M–$4.2M range and market heavily to tech, university and outdoor lifestyle buyers.
Potential Use Scenarios
- Targeted digital campaigns to Denver/Boulder professionals and University leadership.
- Staged open houses emphasizing indoor-outdoor living and basement entertainment spaces.
- Pre-listing inspection to reduce buyer objections around mechanicals and solar equipment.
- Offer detailed systems package (solar ownership docs, generator service records, water/air purification maintenance).
Risk Factors
- Higher carrying costs and transaction friction at luxury price points.
- Potential buyer scrutiny over custom finishes leading to negotiation on price for perceived finish refresh.
- Local zoning/permit questions for studio/accessory use if buyer intends rental conversion.
Buyers should conduct independent due diligence before making any purchase decisions.
