    Why Choose Us?

    Stunning Chelsea basement conversion, how the Greenlife Contractors Team work?

    Step 1. Planning & Design

    An initial consultation
    We’ll come to your home in Chelsea or you can drop into our office. This initial meeting will allow us to understand your goal, listen to your requirements and design the space you want. Our surveyor will then assess your property and discuss your needs briefly and the practicalities of the project. Within days of this initial consultation we will provide a detailed proposal with an estimated budget.

    Design and schematics:
    This is where your ideas start taking shape. The architectural designs and schematics will give you an accurate picture of how your basement will look. When you’re happy with the plans and have approved the budget, we can apply for the necessary permissions.

    These are important documents for you. Our team will always appreciate that this is your home and endeavour to minimise the impact the construction has on your life. A detailed schedule of works gives you an itemised list and costings of key features of your project. Finally, we will estimate the amount of each valuation and give you predictions of when these are to fall due.

    Planning and structural designs:
    Our team of Project managers, builders will manage this whole process: structural designs and calculations are drawn up to create a practical blueprint for your new living space and planning consents obtained for the Chelsea area so the construction can begin. This is the point your ideas take shape. GreenLife Contractors provides the structural designs and calculations to create a practical blue print for your new living space. When these detailed designs have been approved the job of construction can begin.

    Planned time frames:
    Successful project management is all about communication. Greenlife contractors are a tight knit and efficient team and while we’re in your home we make sure that you are kept up to date and happy with our progress. Efficient communication avoids problems and delays and is the best way to keep to budget and schedule.

    Step 2. Construction

    On site management
    The Chelsea builders team has skills and experience that general contractors don’t have. As such, it is common for us to undertake all the works for you, both above and below ground such as side extensions, floor renovations and even whole house refurbishments! However, if you have a current team we are pleased to undertake only the specialist (under)ground works if you wish.

    In the creation of basements in the Chelsea parts of London, it is common for us to be the sole contractor on projects.

    Specialist ground works
    We will include all excavation and removal of spoil, reinforced concrete and steel works, together with all temporary and permanent propping works, followed by the waterproofing and drainage that are so critical.
