Why Choose Promaester Ltd

When it comes to extending your home, choosing the right builder is crucial. At Promaester Ltd, we stand out for several key reasons.

Expert Project Management

Our approach to project management sets us apart.

Every extension project is meticulously managed from start to finish, ensuring smooth progress and adherence to timelines.

We provide detailed Gantt chart timelines for full visibility, and our daily updates keep you informed every step of the way.

Price Guarantee

Financial clarity and no surprises are central to our ethos.

The price quoted in our detailed, written quotations is guaranteed.
We adhere to the quoted price for the agreed scope of work, meaning no hidden costs or unexpected charges.

Customer-Centric Approach

Our business revolves around your needs and preferences.

We engage with you closely throughout the project, from initial design discussions to final touches, ensuring the end result aligns perfectly with your vision.

Your satisfaction is our top priority, and we're committed to turning your ideas into a reality.

Our Process

Here's a quick scenario that most of our clients take.

Step 1 - Get in touch

Give us a call or drop an email to book a site visit.

Step 2 - Initial site visit

Our process begins with a thorough consultation to understand your needs and preferences for the extension.

We discuss your goals, style preferences, and functional requirements.

At the same time, we assess the space and identify any potential challenges or limitations.

Step 3 - Design & Planning

If you already have an architect and drawings, that's good. We can skip this step and proceed to the next step.

If you don't have an architect, we can develop the plans and navigate the planning permission process for you.

If we can build under permitted development, you won't have to do any of the above.

Step 4 - Written Quotation

Once we have an idea what you're after, we take it back to the office and have a discussion with our quantity surveyor (QS).

Then, we proceed to working on your quote. We will submit a written quotation to you within 72 hours, or if you prefer, we come out again to see you in person, so we can go through the quote together line by line.

We get very detailed. Take a look at one of the recent quotations submitted to one of our clients below.

Step 5 - Contract

Upon agreement, a contract outlining the start date, scope of works, price guarantee, and timeline is signed by both parties.

Extension in Sutton Coldfield (Walmley)

Absolutely stunning single-storey rear, and double-storey side extension built in 2022 for our dear clients Geynor and Craig.

Measuring approximately 80 square metres, we've added a downstairs playroom, utility room, extended kitchen-diner area, upstairs bedroom and a spacious en-suite.

Lovely kitchen from Wren and floor tiles from Topps Tiles. Brilliant white Dulux on the walls and ceilings for a nice contrast with the blue accents.

Upstairs bedroom with in-built shelving units to the right.

And lastly, the front of the extension to the right. Classic uPVC cladding with a GRP flat roof and a bay window to match existing.

Extension in Worcester (Ronkswood)

Here we've also got a large double-storey side and a single-storey rear extension for our lovely clients Amanda and Kyle.

Measuring nearly 60 square metres, we've added a large kitchen to the back, an office, a utility with a WC downstairs as well as a bedroom with an en-suite upstairs.
