Impeccable Design

Cosy Conversions

Spacious Extensions


Building is scary, but not with us!

We provide everything you need to know up-front and before the job starts, so you know exactly what’s involved. We also offer regular updates on the progress of the job, and are always on the other end of the phone should you have any questions.

When it comes to the build itself, we are specialists at what we do. We’re like a transformer that can complete any mission in record time, then clean up afterwards. Eat your heart out, Optimus Prime.


Want more space? We offer a range of extensions including:

  • Single storey back or side extensions
  • Double and triple storey extensions
  • Conservatories, outhouses and orangeries
  • Garages
  • Loft or attic conversions (see next section)

Book a site visit today and we’ll provide a quote and a good chin wag.


Recent research by Nationwide Building Society has estimated that a loft conversion could add 20% to the market value of your home.

But why sell at all when you can make extra space for your new baby, coming-of-age teen, or let’s face it, your own office, study or games room?

Many loft conversions utilise the space that is already available, so give us a call and we’ll dust off the cobwebs. It’s a secret place you never even knew you had.


Pick this service if you want to avoid structural changes, but still provide your home with some needed TLC.  We can replace tired decor and neglected fixtures and fittings with an elegant new look.

So go ahead and spruce up your living space with a renovation or refurbishment.

And yes, you can finally get those rusty taps replaced. A new bathroom and kitchen will make you a happier human.

Site visit, consultation & quote

Sometimes it’s easier to talk about what you want if you’re standing in the space you want to change. We offer a 30-45 minute consultation at your home or premises. Put the kettle on and enjoy a meeting of minds as we explore different options and cost breakdowns for your project. We always take the time and care to listen to questions and concerns, and communicate our answers in plain English. We will even draw you a sketch or two so you can visualise your project coming to life.

Got questions? We respond to every query within 48 hours.


Augment (that’s us) have been in the building business for over a decade. We provide building, renovations, extensions and conversions to homes and businesses in London, and the surrounding counties.

The team is led by architect and builder Jay Gasson, a gent with a lot of letters after his name. Jay has a holistic approach, which means he can understand everything from the technical structure of a building, to the breathability and sustainability of the materials used. He also has the hands-on experience to communicate with our network of skilled labourers, and ensure a quality finish.

We’ve had a lot of hugs, handshakes and atta-boy’s from our customers, so we’re confident that you will find our design intelligent, functional and long-lasting. But don’t just take our word for it, read our customer testimonials below, or get in touch for a free, no-obligation chat about your project.

We respond to every query within two working days.
