Our Design-Build Services

We’re Toronto’s preferred premier contractor for residential design-build services. We also offer complete property maintenance as an add-on service following project completion, particularly for larger residential properties. Here’s an overview of our top-tier residential services:

Custom Homes

We offer full custom home construction and design services, including site assessments, permit acquisition, architectural and engineering drawings, and interior design. We design and build large-scale and luxury homes, including custom homes with 8,000+ sq ft. 

Full Home Renovations

Client understanding is one of our top priorities from the start of every renovation. We make sure you have all the details, big and small, such as property utility capacity and zoning by-laws. We also offer assistance with service connections, builder’s risk insurance, and potential liabilities.

Home Additions

Each home addition includes drawings and layouts, material samples and shopping assistance, as well as options for budget-saving alternatives. Execution involves meticulous oversight, including protecting existing structures, dust control, and on-site project management. We use a CRM portal for progress tracking, with all trades uploading progress photos.

Basement Renovations

We handle basement finishing and renovation projects. This service includes on-site design consultations, project management, material sourcing, permit acquisition, and interior design. We work with licensed and experienced tradespeople to complete basement renovations skillfully with flawless execution.

We also offer optional 24/7 property maintenance services. The following is a detailed overview of our commercial services:

Do It Right the First Time

We have a project manager onsite to review, oversee, and serve as the primary contact. To make sure everything is in order, Ash Moeini, Founder and Creative Director, personally inspects each job site for quality, consistency, and accountability.

Communication

From day one, communication is our priority. We will always be transparent about the budget, feasibility and educating clients in long term solutions. Using our software management tool, we document progress, organize project photos, and keep clients updated throughout the build.

Our Design-Build
Process

More than your average custom home builders, we’re a full-service design-build firm. This means we take care of every detail from concept to completion. 



The following outlines of 4-step design-build process:

We begin with a phone consultation, then book an appointment for an onsite assessment. During this stage, we compile the necessary information, including measurements, layouts, photos, wishlist items, project needs, site conditions, and early feasibility considerations. Afterwards, we provide an estimated cost based on the initial scope.

We start the design stage by creating drawings and layouts. If 3D renderings are required for permits or improved visualization, we provide them.

Our team also helps curate material selection, samples, and shopping support, while coordinating with architects, engineers, and consultants where required.

Our team handles all permit application requirements and submissions. Once we put the design-build package together, we work with you to approve and order everything. Before construction begins, we thoroughly cover everything to protect against dust and damage, including finished surfaces where needed. During construction, we use a CRM portal to document progress and keep clients updated. Ash is also involved with each project personally inspecting job sites to ensure quality, consistency, and accountability.

After construction, we perform a walkthrough, schedule inspections, conduct a client satisfaction check, and go over warranty information. We also provide scheduled property management for large residential homes and commercial properties.
