Architects in Chelsea

Every architectural design and management project consists of the following four stages:


The feasibility stage comes before the design planning stage. It is where our architects will evaluate your residential or commercial property to determine if it can sustain your architectural design requirements.

For instance, our architects will review the entire property’s history to learn about the buildings, renovations, and demolitions that may have occurred in the past. In addition, we’ll examine the soil and ground to see if it can withstand the type of building structure you want to construct on it.

The feasibility stage will avoid any costly and time-consuming setbacks in the future. Once we verify that your property can accommodate your project requirements, we can proceed to the planning stage.


The planning stage is where we begin planning the details and framework of your architectural project. First, our architectural team will sketch concept designs and plans for the particular structure you would like to construct. After that, we’ll submit those sketches and plans to your Local Authority for approval.

The Local Authority is the governing agency that must ensure your architectural project complies with local building codes and regulations. For this reason, they’ll want to see planning documents and sketches of the proposed structure to determine whether it violates any building codes or regulations. If the Local Authority finds no violation, it will approve your project for construction.

Technical Design

Modern building developments are complex in design and management. The technical design stage is where our architects use our advanced skills, tools, materials, and knowledge to create effective construction methods for overcoming challenging architectural design tasks. Our knowledge consists of high-level architecture, building science, and engineering skills.


We will work with you in the construction stage to find the best contractors to build your structure. Our team will connect with the most reputable licensed contractors and require price quotes for their building development services. Once we gather this information, we’ll share it with you and recommend who to hire.
