Before & After: Converting a Traditional Home to Modern Design

Discover how we transformed a 1930s colonial into a stunning modern family home while preserving its best features

The Challenge: A Mismatched 1930s Home Needing Cohesion

When the Morrison family contacted us, they were living in a 1930s home that had been modified haphazardly over the decades. Multiple additions, varying roof lines, and different ceiling heights created a disjointed, maze-like interior. The dark, choppy spaces felt cramped despite the generous square footage, and the exterior lacked any architectural cohesion.

Like many homeowners with vintage properties, they faced a difficult decision: demolish and rebuild, or find a way to unify what they already had?

What They Wanted:

  • Open, light-filled spaces perfect for entertaining

  • A seamless indoor-outdoor connection

  • Clean, contemporary lines with warmth

  • Energy-efficient systems and materials

  • A home that reflected their modern lifestyle

The verdict? A comprehensive renovation that would reimagine their home from the inside out.

Before: Understanding What We Had to Work With

The Original Home's Challenges

The existing home was a patchwork of additions spanning nearly 90 years:

  • Mismatched roof lines - Three different roof heights from various additions

  • Inconsistent ceiling heights - Ranging from 7'6" to 9 feet across different rooms

  • Closed-off floor plan - Original 1930s compartmentalized layout

  • Multiple floor levels - Awkward steps between additions

  • Confused exterior - No unified architectural language

  • Small windows - Original 1930s openings with replacement windows of varying styles

  • Outdated systems - Pieced together over decades, extremely inefficient

But it also had significant potential:

  • Solid perimeter foundation and walls

  • Substantial square footage already in place

  • Established mature landscaping

  • Desirable neighborhood location

  • Original structural walls in good condition

The key insight: we could keep the existing perimeter walls (saving considerable cost and waste) while completely reimagining everything above and within.

The Design Strategy: The Bold Solution

Our approach was both radical and resourceful: remove the entire roof structure and rebuild from the walls up.

This strategy allowed us to:

1. Create Unified Ceiling Heights Throughout

By removing all existing roofs and framing, we could establish consistent 10-foot ceiling heights across the entire home, eliminating the awkward steps and cramped spaces that had accumulated over decades.

2. Establish a Cohesive Architectural Language

A completely new roof structure meant we could design one unified modern form that tied the entire home together visually. No more mismatched additions—just one coherent architectural statement.

3. Maximize Spatial Volume While Keeping Costs Down

Keeping the existing perimeter walls saved us approximately 30-40% compared to full demolition and rebuild. We reused the solid foundation and structural walls while gaining the freedom to completely reimagine the interior volume.

4. Allow for Dramatic Natural Light

The new roof design incorporated strategic skylights, clerestory windows, and vaulted spaces that would have been impossible with the old, fragmented roof structure.

5. Future-Proof the Systems

With everything exposed during the roof rebuild, we installed state-of-the-art insulation, HVAC, electrical, and plumbing systems properly integrated into the new structure.

The Transformation: Key Changes Room by Room

The Roof Removal Process: The Game-Changer

The Challenge: How do you live in a house while removing its entire roof?

The Solution: Strategic phasing and temporary weather protection.

We worked in sections, protecting living areas with temporary roofing while framing new sections. The entire roof removal and replacement took 6 weeks, with the family temporarily relocating for 3 of those weeks during the most intensive phase.

What We Gained:

  • Eliminated all mismatched rooflines and ceiling heights

  • Created a clean, modern flat roof with concealed drainage

  • Added 18 inches of ceiling height throughout

  • Installed continuous rigid insulation (R-40) impossible with the old structure

  • Incorporated multiple skylights and clerestory windows

  • Unified the entire home under one architectural gesture

Structural Innovations:

  • Retained existing perimeter walls but reinforced where needed

  • New engineered lumber roof system optimized for open spans

  • Steel beams at key locations to eliminate interior load-bearing walls

  • All new tie-downs to meet current seismic codes

Kitchen & Living Area

Before: Multiple small rooms with varying ceiling heights (7'6" in kitchen, 8' in dining, 9' in living room) and no connection between spaces.

After: A 900-square-foot open-concept space with uniform 10-foot ceilings featuring:

  • Minimalist white oak cabinets with integrated appliances

  • 12-foot island with waterfall quartz countertops

  • Full-height glass walls facing the backyard

  • Polished concrete floors with radiant heating

  • Three large skylights bringing southern light deep into the space

  • Exposed structural beams painted white for visual interest

Design Details:

  • Eliminated upper cabinets on exterior wall to accommodate new floor-to-ceiling windows

  • Created hidden pantry and appliance garage for clean lines

  • Installed commercial-grade ventilation integrated into new roof structure

  • Consistent ceiling plane unifies formerly disjointed spaces

Primary Suite

Before: Standard bedroom with small windows, separate dated bathroom with tub surround.

After: A spa-like retreat with:

  • Floor-to-ceiling glass overlooking private garden

  • Custom millwork creating floating nightstands and storage

  • Wet room bathroom with walk-in shower and soaking tub

  • Terrazzo flooring and matte black fixtures

  • Wood slat accent wall adding warmth

Exterior Transformation

Before: A chaotic mix of roof lines, materials, and styles accumulated from decades of additions. The home had no clear architectural identity.

After: A unified contemporary statement featuring:

  • Single flat roof plane with hidden parapet and drainage

  • Smooth stucco cladding in warm gray covering all perimeter walls

  • Horizontal cedar siding accent panels defining entries

  • Strategic window placement creating rhythm across facade

  • Oversized pivot front door with vertical grain walnut

  • Integrated garage that reads as part of the main volume

  • Subtle reveals and shadow lines adding depth

  • Preserved mature trees framing the new composition

The Roof Design: The new flat roof extends beyond the original walls with generous overhangs, creating covered outdoor spaces while protecting walls from weather. Concealed gutters and downspouts maintain clean lines. The unified roof plane transforms what was once a fragmented collection of additions into a single, powerful architectural form.

The Numbers: Investment & Value

Project Stats:

  • Timeline: 9 months (design + construction)

  • Original square footage: 1,800 sq ft

  • New square footage: 3200 sq ft (reconfigured, not expanded)

  • Perimeter walls retained: 100% in the lower floor

  • Roof structure: 100% new

  • Energy efficiency improvement: 60% reduction in heating/cooling costs

  • Investment range: $420,000 - $500,000 (your costs will vary)

What This Included:

  • Architectural design, engineering, and permitting

  • Complete roof demolition and rebuild

  • Structural reinforcement of existing walls

  • All new windows and doors throughout

  • Complete interior reconfiguration

  • Full kitchen and bathroom renovations

  • New HVAC, electrical, and plumbing systems

  • Exterior re-cladding and waterproofing

  • All fixtures, finishes, and millwork

Why This Approach Saved Money:

By keeping the existing perimeter walls and foundation, we saved an estimated $120,000-150,000 compared to full demolition and rebuild, while still achieving a completely transformed home. We also avoided 6-8 months of additional construction time and significantly reduced waste.

Return on investment: The home is now valued at $450,000-500,000 more than comparable unrenovated 1930s homes in the neighborhood. More importantly, the Morrison family has a home that functions perfectly for modern living while respecting the character of their established neighborhood.

Lessons Learned: What We'd Tell Other Homeowners

1. Consider the "Perimeter + Roof" Strategy for Mismatched Homes

If your home has solid exterior walls but a complicated, fragmented roof from multiple additions, this approach can be transformative. You get the benefits of new construction (unified design, modern systems, optimized layouts) at 60-70% of the cost.

2. Don't Be Afraid of Radical Solutions

Initially, the idea of removing the entire roof seemed extreme. But it was actually more cost-effective and less complicated than trying to work with the existing mismatched structure. Sometimes the bold move is the smart move.

3. Engineering Matters More Than Ever

With this approach, structural engineering is critical. We invested heavily in engineering to ensure the retained walls could support the new roof design and meet current codes. This isn't a place to cut corners.

4. Plan for Temporary Relocation

Unlike many renovations where you can live on-site, a roof removal requires planning for temporary housing during critical phases. Budget for this both financially and logistically.

5. The Payoff is Architectural Cohesion

The single biggest benefit wasn't any individual feature—it was the unified architectural language. The home finally makes sense as a complete composition rather than a collection of additions.

Could Your Mismatched Home Benefit from This Approach?

Not every older home is a good candidate for the roof removal strategy, but many mismatched properties have more potential than their owners realize. Here are signs your home might be perfect for this type of transformation:

Excellent candidates have:

  • Solid perimeter walls in good structural condition

  • Multiple additions creating mismatched roof lines

  • Varying ceiling heights between rooms

  • Desirable location where you want to stay long-term

  • Complicated roof geometry that's costly to maintain

  • Adequate lot size for modern indoor-outdoor living

  • Foundation and walls that meet (or can meet) current codes

This approach works especially well for:

  • 1920s-1950s homes with multiple additions

  • Bungalows or cottages expanded over time

  • Ranch homes with fragmented roof lines

  • Properties where full demolition seems like the only option

Consider other strategies if:

  • Perimeter walls have significant structural issues

  • Foundation problems would require extensive work regardless

  • Home is severely undersized for your needs

  • Local regulations make roof height increases difficult

  • Cost approaches new construction despite savings

The Decision Framework

Ask yourself:

  1. Are the existing walls worth keeping structurally?

  2. Is the current roof creating more problems than solutions?

  3. Do you need unified ceiling heights throughout?

  4. Would you rather renovate than relocate?

  5. Can you handle temporary displacement during construction?

If you answered yes to most of these questions, the perimeter + roof strategy might be perfect for your home.
