Astaneh Construction For Your Next Custom Home and Major Renovations

We have planned and built custom homes, full-home renovations and major additions across Toronto and the GTA. Established in 2013, Astaneh Construction is a licensed and insured Toronto renovation company built around careful planning, honest communication, skilled execution, and founder-led project guidance.

We're HCRA-licensed and Tarion-registered, and our renovation work carries a one-year workmanship warranty after handover.

Best of Houzz named us for service in 2023 and again in 2024, and the Quality Business Awards recognized us as Toronto's Best General Contractor in 2024. Trusted industry recognition and affiliations include RenoMark, BILD, Tarion, Houzz, NKBA, WSIB, Top Choice Awards, and a Toronto Licensed Contractor badge supporting our work.

From the First Site Visit to Handover

Whether you’re building a custom home or making substantial changes to an existing house, the work starts with understanding the property and the decisions ahead.

1. Consultation & Feasibility

We start with a conversation about the property itself. Your goals, your must-haves and the scope you have in mind. This stage also includes an early feasibility review, so you know what the site can realistically support before we go further.

2. Design Development 

Once we understand the property and your goals, we develop the project around how you actually want your home to function. That covers layout, design direction and the major selections that shape the space, worked through together before anything moves into drawings or construction.

3. Budget & Timeline

With the design direction set, we define the proposed scope and prepare a budget proposal and timeline. This spells out what's included and what's excluded so there are no surprises once construction preparation begins.

4. Drawings, Permits & Pre-Construction 

Before work starts on site, we coordinate the drawings, required permits, and material selections that must be finalized in advance. This stage also covers any remaining preparation, so the project can move into construction without delays once everything is approved.

5. Construction & Project Management 

During construction, we keep the site, schedule, and trades and consultants aligned as the project moves forward. That means regular updates, clear communication, and one point of contact, so decisions are made quickly and work keeps moving without unnecessary delays.

6. Completion & Handover 

At the end of the project, we complete a final inspection and walkthrough together, addressing any finishing items you flag along the way. We'll also review your handover documents and warranty information, so you know exactly what's covered before you settle into the finished space.

One Coordinated Process, Start to Finish

Every major residential project involves decisions, timelines, and details that need to stay coordinated. We keep the process organized from early planning through construction and final handover.

Renovation Ideas That Fit Toronto Homes

Homeowners across Toronto are gravitating towards renovation ideas that combine elegance, comfort, and long-term value. Many of today’s most sought-after designs also support energy-efficient home renovation while maintaining a timeless aesthetic. And that’s what we offer at Astaneh Construction. We’re here to help you discover trends that provide a timeless aesthetic for your home renovation in Toronto.

This trend prioritizes simplicity over elaborate elements without feeling cold and uninviting. Clean lines, uncluttered spaces, and subtle textures create warm interiors that feel intentional, inviting, and easy to live in.

Natural, light-toned woods bring warmth and softness to kitchens and bathrooms. They pair beautifully with modern finishes while keeping spaces bright and visually open.

Brushed brass and champagne-toned metals add subtle luxury. These accents introduce contrast and depth that support both contemporary and transitional renovation designs.

A waterfall marble island creates a striking focal point in modern kitchens. The continuous stone surface adds visual interest and is stunning, giving your kitchen the wow factor you’ll appreciate for years to come.

Layered neutrals like soft whites, warm greys, and earthy tones add dimension without overpowering the space. This colour palette allows architectural details and finishes to stand out.

Questions About Custom Homes and Renovations

Our project management team in Toronto saves you the hassle and stress of coordinating with dozens of subcontractors and keeping track of multiple budgets. Working with a renovation company means you won’t have to find and negotiate with millwork companies, tile guys, painters, and everyone else by yourself. Our project management team ensures you experience a more efficient and cost-effective process.

Choosing a renovation company isn’t a decision you make lightly. Your choice can make or break your entire project in Toronto. First and foremost, you want to partner with a company that prioritizes quality. The following key aspects to look for are cost and customer experience. Check out the Astaneh Construction Price Guide page for more information.

One of the best ways to assess renovation contractors’ quality of work is to look at their past and present projects. You can do this by visiting their active or completed construction sites. You can visit a project at any stage (whether it’s demolition, framing, or drywalling) and assess the quality of their workmanship. How a renovation contractor handles one job shows how they handle all jobs. You can also take a look at the Astaneh Construction portfolio to see finished projects in Toronto and Greater Toronto Area.

Yes, our renovation services are backed by a one-year workmanship warranty. If a problem arises or you have any concerns within the 12 months following project completion, you can give us a call and we’ll send a team to help. Customer satisfaction is a primary focus at Astaneh Construction and if you aren’t happy with our work then neither are we.

The first step is to call Astaneh Construction. We’ll schedule a free consultation and meet you at your home at a time that’s convenient for you. During the initial consultation, we’ll discuss projects details, talk about your goals, share design ideas, and take site measurements. Visit Our Process page to find out more. Read article Home Renovation Checklist Step-by-Step

We fill out the permit applications and submit them on your behalf. The permitting process in Toronto can be tedious, but our years of experience and extensive knowledge of zoning restrictions, building codes, and local by-laws guarantee a smooth process. Read more in article Renovating Your Home? Read First! Building Permits in Toronto

Possible complications that can occur during remodeling in Toronto include:

  • Unexpected costs
  • Timeline delays
  • Unforeseen plumbing, electrical, or structural
  • problems
  • On-the-job accidents or injuries
  • Design errors
  • Incorrect or undelivered materials
  • Fines for improper permitting

When you work with Astaneh Construction, you have peace of mind because we involve you in every stage of the process. As a customer-first renovation company, we provide you with regular progress updates. We also walk you through the site at various stages, including the demolition, framing, installation, and finishing phases. We make sure you’re comfortable and well-informed from start to finish.

Home renovation costs are based on a variety of factors, including size, scope, customization, labour rates, materials used, and project complexity. To budget for your renovation, you’ll need to account for each factor. Additionally, we recommend allocating up to 20% of your budget to a contingency fund for unexpected costs. Learn more about renovation budgeting by exploring the Astaneh Construction Price Guide.

Relocating during a renovation may be necessary if the project involves major structural, plumbing, and/or electrical work. If this is the case, you might consider staying in a hotel, with family, at an Airbnb, or with friends. However, if you’re having minor renovations performed, such as replacing flooring, repainting walls, or replacing cabinetry, you may be able to stay in your home throughout the renovation with minimal disruptions.

You may be able to claim up to $7,500 on your income tax and benefit return as part of Canada’s Multigenerational Home Renovation Tax Credit. This credit covers certain expenses for the creation of a self-contained secondary unit within your home. In order to qualify, this unit must be built for an adult or senior who receives the Canadian disability tax credit.

Yes. We can start with a review of your lot, goals and any existing drawings. Zoning, site access, servicing and the condition of an existing house all help determine the next steps for a new build.

A new house requires a building permit. The application includes drawings and information about the site, structure and proposed home, with other approvals depending on the property. Renovations and additions have their own permit requirements based on the work. Our team coordinates the drawings and applications within the agreed project scope.

Ontario’s statutory new-home warranty is provided by the builder and backed by Tarion. Coverage includes one year for defects in work and materials, two years for specified issues such as water penetration and defects in electrical, plumbing and heating distribution systems, and seven years for major structural defects. Limits and exclusions apply.

No. Our renovation work carries a one-year workmanship warranty after completion. Tarion’s statutory new-home coverage is a separate program and should not be assumed to cover an ordinary renovation or addition.

Yes. Share the plans and any approvals you already have, and we can review the proposed scope with you and your design team. We can also coordinate drawings and permit support if your project is at an earlier stage.

The decision depends on what the existing house and lot can support, the space you need and the budget for the work. A renovation may resolve layout and systems issues, an addition can create more room, and a custom rebuild allows you to plan a new house. We can discuss these options at the first property visit.

Yes. Our pre-purchase consultation helps you explore renovation or rebuilding potential and preliminary costs. It does not replace a home inspection, engineering assessment, property valuation, legal advice or municipal approval.

How much does it cost to renovate a house in Toronto?

Renovating a house in Toronto isn’t a one-size-fits-all price tag. Costs vary based on the size of your home, the condition it’s in, and how far you want to go — whether it’s surface updates or a full interior rebuild.
