Why Clients Hire Design by Teresa
Thoughtful Planning Before Construction Begins
Every successful renovation starts with a clear plan. We help homeowners make confident decisions before construction begins, reducing costly changes and unnecessary surprises later.
Guidance Through Complex Renovations
From layout changes to permits and construction coordination, we help simplify a process that can often feel overwhelming.
We know that a renovation is more than a construction project.
It is an investment in how you and your family will live for years to come.
That is why we approach every project with professionalism, genuine care, and a passion for creating homes that work beautifully in everyday life.
A house can look impressive.
A home should feel right.
Professional
A successful renovation involves far more than selecting finishes and furniture. It requires careful planning, technical knowledge, and the ability to see the bigger picture before construction begins. From space planning and layout design to material selections and project coordination, we help homeowners make informed decisions that reduce costly mistakes and create long-term value. Our clients trust us to bring clarity and direction to what can often feel like an overwhelming process.
Personal
Every family is different, and every home tells a different story. We take the time to understand our clients' goals, concerns, and priorities because good design is never just about the space itself. It is about the people who live in it. We believe a successful project is built on communication, trust, and genuine care. Our clients are not simply another project on a schedule—they are families creating a home for the next chapter of their lives.
Passionate
Design is not just what we do—it is what we love. We are passionate about finding opportunities others may overlook, solving challenges creatively, and transforming spaces into homes that truly support everyday living. Whether it is reimagining a floor plan, improving functionality, or helping clients make confident decisions, we approach every project with the same goal: creating a home that feels beautiful, practical, and deeply personal.
Why Hire an Interior Designer for Your Renovation?
Most people think interior design is about choosing materials, colours, and furniture.
In reality, the most important design decisions happen long before any of those selections are made.
Great design is about creating a home that functions better, feels more natural, and supports the people living in it. Through thoughtful planning, better space utilization, and strategic decision-making, interior design helps homeowners invest their renovation budget where it matters most.
Design Is Not an Expense — It Is a Strategy
Many homeowners hesitate to hire an interior designer because they see it as an additional cost. In reality, thoughtful design often saves money by preventing expensive changes later. The most successful renovations are rarely the ones with the biggest budgets. They are the ones where every decision is made with purpose. Good design helps homeowners understand where to invest, where to simplify, and how to maximize the value of every dollar spent.
Better Space Planning Creates Better Living
Most renovation projects focus on what people can see — flooring, cabinetry, lighting, and finishes.
What often has the greatest impact, however, is what people don't immediately notice: how a space flows, how rooms connect, and how comfortably a family can live within it.
A thoughtful floor plan can make a home feel larger, brighter, and more functional without adding a single square foot.
A Home Should Work for You
At Design by Teresa, we believe a home should adapt to the people living in it—not the other way around. Beautiful finishes and carefully selected furnishings are important, but they should support a larger purpose. The goal is to create spaces that feel natural, comfortable, and effortless to live in. When thoughtful planning comes first, the result is more than a beautiful home.
A beautiful home is easy to photograph.
A well-designed home is one you enjoy living in every single day.
Before You Start Renovating: 3 Decisions That Shape Everything
Same footprint. A completely different way of living.
Every successful renovation begins long before construction starts.
Long before materials are selected or walls come down, the most important decisions have already been made. A well-designed home begins with understanding how you live, what your family needs, and how every space should support daily life. When those decisions come first, the entire renovation becomes more intentional, more enjoyable, and far more rewarding.
1. A Beautiful Home Begins With the Way You Live
It's easy to fall in love with beautiful cabinetry, countertops, and lighting.
But before choosing finishes, take a step back.
Think about how the home functions every day.
Where does the family naturally gather?
What feels inconvenient?
What would make everyday life easier?
When the layout is right, every design decision becomes much clearer.
2. The Right Team Shapes Every Decision That Follows
Beautiful materials alone don't create a successful renovation.
Behind every well-designed home is a team that understands planning, communication, craftsmanship, and execution.
The earlier the right professionals become involved, the easier it is to solve problems before construction begins—not after.
3. True Value Goes Beyond the Price Tag
The lowest quotation isn't always the best value.
Every proposal includes different scopes of work, different materials, different levels of craftsmanship, and different standards of project management.
Understanding what's included often matters far more than comparing the final number.
A renovation isn't simply about completing construction—it's about creating a home that continues to serve the family for years to come.
Interior Design FAQ
How much does a whole-home renovation cost in the GTA?
It depends on the size of your home, the scope of work, and the level of finishes. As a planning guide, GTA homeowners often budget roughly $150–$350 per square foot for a whole-home renovation with quality finishes, with kitchens and bathrooms costing more per square foot than living areas. Structural changes, permit requirements and material selections move the number up or down — which is why we start with a consultation and a clear design plan before any construction pricing is finalized.
How long does a whole-home renovation take?
For most projects, the design phase — consultation, floor plans, selections and 3D visualization — takes several weeks, and construction typically runs three to six months depending on scope and permits. A realistic timeline is set after we see your home and understand the full scope; we would rather give you an honest schedule than an optimistic one.
Do I need a building permit for my renovation?
Often, yes. In Ontario, renovations that change structure (such as removing a load-bearing wall), relocate plumbing or electrical, finish a basement, or alter the layout generally require a building permit and technical drawings. Cosmetic updates like painting and replacing finishes usually do not. Our service includes permit and technical drawings, and we confirm what your specific project requires during the consultation.
How are your design fees structured?
After the initial consultation, design services are quoted as one fixed fee based on the scope of your project — you know the full design cost before we begin, with no hourly surprises. The proposal sets out exactly what is included: space planning, design development, 3D visualization, drawings, and the level of on-site support you choose.
What does the $499 consultation include?
The consultation is an on-site visit to your home: we review your space, listen to how you live and what you want to change, and give you honest, professional guidance on feasibility, budget and next steps. If you move forward with a full design engagement, the $499 consultation fee is fully deducted from your design fee.
Which areas do you serve?
We are based in Richmond Hill and serve homeowners across the Greater Toronto Area — including Markham, Vaughan, North York, Toronto, Aurora, Newmarket, King City, Mississauga and Oakville.
Are 3D renderings included in the design service?
Yes. For full design projects, 3D renderings and panoramic visualization are part of the process — you can walk through your future home and make confident decisions before construction begins. It is one of the best ways to avoid costly changes on site.
I already have my own contractor. Can I hire you for design management only?
Yes. Many clients come to us with their own contractor and hire us for design and on-site support: design direction, on-site consultations, coordination with your contractor and trades, site reviews, and verification that the finished work matches the design. You keep your team — we make sure the result is the home you planned.
How much does a kitchen renovation cost in the GTA?
Most full kitchen renovations in the GTA fall between $60,000 and $150,000 or more, depending on the size of the kitchen, whether the layout changes, and the level of cabinetry and finishes. Custom cabinetry, natural stone countertops, panel-ready appliances, and moving plumbing or walls move the budget up; keeping the existing layout and refreshing the finishes brings it down. In our design process, selections are made and priced before construction begins — so your kitchen budget is a plan, not a guess.
Can I live in my home during the renovation?
Sometimes — it depends on the scope. For a single-area project, such as one bathroom or a basement, most families stay in the home while the work is underway. For a whole-home renovation — especially when the kitchen and bathrooms are out of service, or structural work is involved — most families move out for at least the heaviest phase. During the design phase, we plan the sequence of work around your family, keeping one bathroom functional where possible, and we will tell you honestly, before construction starts, whether staying is realistic for your project.
How far in advance should I start talking to a designer?
Earlier than most people expect — ideally, start the design conversation three to six months before you want construction to begin. The design phase itself takes several weeks: consultation, floor plans, selections, 3D visualization and permit drawings. After that, permit approval adds municipal review time, custom cabinetry and stone are made to order, and good contractors book months ahead. If you hope to start construction in the spring, the time to start designing is the winter before. Starting early is what keeps a project calm — and keeps your budget and timeline under control.
