APT Renovation Design & Build are a premier construction company based Balham, South-West London. We have an outstanding team of first-class architectural designers, interior designers and builders that will cover every facet of property refurbishment to create your dream home.
You can relax knowing that your home will be constructed to the highest standard and we always make sure that everything is done within the letter of the law, giving you full peace of mind. Whether it's a house extension, basement conversion or house renovation, from first consultation through to the final completion and handover, our team are totally dedicated to your success.
We are one of the very few firms who choose not to ask for deposits or upfront payments. We get work started for you (including scaffolding, skips and purchase of materials), and you only start making payments to us once we are underway and you are happy with the progress so far.
Our construction team will be at hand for you every step of the way to ensure that your project runs smoothly, and in the way that you envisioned, offering full transparency in the process. The happiness of our customers is of paramount importance to us, which is why pride ourselves in bespoke customer care, and attention to all the fine details.
We are happy to work on projects across London from as little as £50,000 and are able to provide a full service for jobs right up to £3m+. We also offer a comprehensive architectural design and visualisation service.
Our team includes:
Project managers
Pre-contract & contract managers
Architectural designers
Design consultants
Quantity Surveyors
Structural Engineers
Professional Builders.
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.
