We use premium exterior materials and work with experienced designers to ensure your addition matches your home’s original finishes – from rooflines and siding to windows and trims — creating visual harmony inside and out.

Our Proven Process for Home Additions

Our refined design-build approach – The Grindstone Way – ensures your Winnipeg home addition is beautifully executed, well-planned, and stress-free from start to finish.

Phase 1 - Design & Feasibility Planning
We begin with a deep understanding of your goals and lifestyle needs. Through site visits and collaborative planning, we develop conceptual designs, confirm zoning allowances, and outline a preliminary scope and investment estimate.
Phase 2 - Final Design & Fixed Pricing
All architectural plans, engineering, and permit requirements are finalized. We guide you through premium finish selections and provide detailed 2D or 3D renderings when applicable. You receive a comprehensive fixed-price proposal with a clear timeline and payment schedule – no surprises.
Phase 3 - Expert Construction Execution
Your project manager and site superintendent ensure every step of construction runs smoothly. From foundation and framing to roofing and finishing, our vetted trade partners and in-house craftsmen maintain the highest standards – while Buildertrend gives you full access to daily logs, progress photos, and timelines.
Phase 4 - Completion, Care & Warranty
We conduct a full walkthrough, activate your 3-year warranty, and deliver documentation and care guides. From day one to move-in day, our focus is delivering a stunning addition that blends perfectly with your home – and stands the test of time.
