Who we are

Hammerhead General Contractors Ltd was founded by Emil Waszkiewicz in 2010 and works throughout London and the Home Counties.

After an early career as a fine dining chef, Emil launched Hammerhead GC; a bespoke one-stop-shop design and build company for residential and commercial projects. He provides unparalleled attention to detail, whether it be during the original design phase, throughout a build or during decorative projects.

Hammerhead covers both the domestic and commercial markets, and ranges from loft and basement conversions to new build projects, renovations and everything else in between.

He works regularly with a select team of tried and tested, specialist contractors, as well as regular collaborations with a number of leading west London architects and design companies.

Emil prides himself having created a design and build company that is fully transparent and excels at collaborating, liaising and communicating fully with clients at every stage of the project.

What we do

Hammerhead is a one stop shop for domestic and commercial building projects. Our range of experience and expertise enables practical inspiration, bespoke creativity and flexibility for each project, whilst adhering to client budget.

Hammerhead has been responsible for several new build projects, loft and basement extensions as well as house and commercial property renovations. We also work on smaller standalone projects such as bathroom and kitchen refurbishments.

With our combined expertise in all aspects of construction, extensions, renovations and alterations we will help with all aspects of a building project. We are fully insured for your peace of mind.

Since launching we have also been called in to rescue several failed projects where clients have been left in the lurch by other contractors and have been responsible for turning these around to a successful conclusion.

We always provide prospective clients with at least two references and can arrange for site visits on request.

At Hammerhead, we believe that everything is possible – whatever your concerns, physical constraints or budgetary boundaries, we will do our best to find a solution…. but don’t take our word for it.. take a look at our testimonials to see what our clients say about us.

Our Ethos

Hammerhead has the expertise, experience and scale to undertake large domestic and commercial projects but is still small enough to care about each individual client.

We pride ourselves on understanding the stresses associated with carrying out building works of any kind. It goes without saying that choosing the right builder is crucial in minimizing that stress and for us, it’s all about collaboration and communication. We will take you through each stage from the initial meeting through to handing over the key of the door to a new property.

After six years, Hammerhead has built up a solid reputation – most of our projects come through personal recommendation. Several clients have also engaged Hammerhead for multiple projects, testimony to our attention to detail to the very end of each project.
