We know that it can be difficult for home owners to find an architectural designer, apply for planning permission and then find a reputable builder. The benefit of our service is that we do all of this for you.

We work directly with the architectural designer, so you only have to deal with us.

We are able to manage everything for you throughout the entire design and build process.

Our service is fully comprehensive, covering everything from your initial design ideas briefing, right through to the completion of your project.

Why are we different?

APT Renovation was born when we saw a gap in the housing market, with belief that we could make the whole building process easier and better. Our company specialises in designing and building the best basement conversion, extension, renovations and loft conversions with the highest attention to detail.

APT Renovation recruits experienced and creative architectural designers and Engineers from within the industry, as well as utilising the smart and efficient process to manage projects and client focused business models.

The result is easy access to your project information, better communication as well as seamless customer experience starting with conceptual project sketches to realistic 3D CAD designs and modelling to plan your future project for better design and budgeting.

Over the years of our existence we have been recommended and gained a remarkable reputation for our innovative basement and extensions designs to complement residential homes, we also had a positive impact on property value.
