Kitchen Bump Out Excellence
Strategic kitchen bump out projects transform cramped cooking spaces into functional culinary areas.

Our bump out addition specialists analyze existing layouts, determine optimal extension dimensions, and design small home extension projects providing maximum functionality per square foot.
Beyond islands, kitchen bump out projects accommodate expanded appliance areas, additional cabinetry, breakfast nooks, or improved traffic patterns. Many Toronto homes have narrow kitchens preventing island installation—a modest bathroom expansion or kitchen extension solves this efficiently. Our contractors ensure seamless integration matching existing architecture.

Small extensions (typically 4-6 feet) provide space for walk-in showers, double vanities, soaking tubs, or improved storage. Our bump out addition team understands that modest square footage gains dramatically improve bathroom functionality and luxury.
Bathroom renovations combined with strategic bump outs deliver exceptional results. We design bathroom expansion projects optimizing layouts, improving plumbing configurations, and creating beautiful, functional spaces.

Our Bump Out Addition Process
From planning through completion, our small home extension experts deliver exceptional results efficiently
1. Needs Assessment & Design
Every successful bump out addition begins with understanding what you hope to achieve. Our team evaluates how you currently use spaces, what functions feel cramped, and what specific improvements would make the biggest impact. We measure existing areas, assess lot dimensions, review zoning requirements, and identify the optimal small home extension approach solving your challenges efficiently.
Design development transforms needs assessment into detailed plans for your kitchen bump out or bathroom expansion. We create layouts optimizing every square inch, ensuring extensions provide exactly the space needed—no more, no less. Our designers present options at various investment levels, explaining how different extension sizes and configurations affect functionality, cost, and construction timeline. We help you understand bump out addition cost factors.
Permit preparation includes architectural drawings, structural engineering calculations, and site plans. Our Toronto renovation team has excellent relationships with building departments across Toronto, Mississauga, and GTA municipalities, enabling efficient permit processing for your small home extension.
2. Foundation & Structural Work
Proper foundation work represents the most critical aspect of bump out addition construction. Our team excavates carefully, installs footings sized by engineering calculations, pours foundation walls or slab-on-grade systems appropriate to project requirements, and ensures proper drainage and waterproofing protecting your investment. Foundation work typically requires 1-2 weeks depending on weather and soil conditions.
Structural framing builds upon foundation systems, creating the skeleton of your kitchen bump out or bathroom expansion. We install pressure-treated plates, wall framing matching existing construction, engineered floor joists spanning between new and existing foundations, and roof systems integrating seamlessly with existing roofs. Our small home extension specialists use quality materials and proven construction techniques ensuring durability.
Structural connections between new and existing construction require particular attention. We install proper tie-downs, bolts, and fasteners creating secure connections. Roof integration involves carefully removing existing roofing where connections occur, installing proper flashing preventing water infiltration, and matching roofing materials for visual continuity. Our bump out addition contractors never cut corners on structural integrity.
3. Systems & Finishing
Mechanical, electrical, and plumbing installations transform framed structures into functional living spaces. Small home extension projects require extending HVAC ductwork, electrical circuits, and plumbing lines from existing systems into new spaces. Our team coordinates all trades efficiently, ensuring proper sizing for extended loads, code-compliant installations, and convenient fixture locations within your kitchen bump out or bathroom expansion.
Insulation installation significantly impacts comfort and energy efficiency in your bump out addition. We exceed minimum code requirements, typically installing R-20 wall insulation and proper air sealing preventing drafts and heat loss. We use products from Owens Corning Canada, ensuring thermal performance and long-term durability. Proper insulation also provides sound control, reducing noise transmission between indoor and outdoor environments.
Interior finishing completes your bump out addition transformation. Drywall installation with proper taping and finishing creates smooth walls ready for painting. Flooring installation—hardwood, tile, or laminate—creates seamless transitions between existing and new spaces. Our contractors match existing trim, select complementary finishes, and ensure beautiful results looking original to your home.
4. Exterior Finishing & Integration
Exterior finishing ensures your small home extension enhances curb appeal and weathers beautifully. We match existing siding materials—vinyl, brick, stucco, or wood—creating seamless transitions between new and original construction. Window installations match existing styles, grille patterns, and proportions maintaining architectural harmony. Roof materials blend perfectly, making kitchen bump out additions look original to the home.
Exterior details complete the integration—soffits, fascia, gutters, downspouts, and proper grading ensuring water drainage away from structures. Landscaping restoration addresses any disturbance during construction, regrading, planting grass or gardens, and creating attractive transitions between bathroom expansion areas and existing outdoor spaces.
Final inspections verify that your bump out addition meets all Ontario Building Code requirements and municipal bylaws. We schedule framing inspections, electrical inspections, plumbing inspections, HVAC verification, and final occupancy inspections. Because we build to exceed minimum standards, our small home extension projects consistently pass inspections without requiring corrective work.
