Xtra Space can turn our clients ideas into a reality, we can assist you in every aspect of the design process, with our in house design team.

We work with MG Architects (mgarchitects.org), our design team, who have many years of experience. They are a vibrant practice offering thoughtful and creative design, with an in depth variety of experience combined with fresh thinking.

We believe in simple design solutions based upon an understanding of traditional and new materials, their suitability and how they can be sensitively brought together. Good architecture is founded in a multi talented team and we believe the starting point to any project is a detailed understanding of context and brief. We are excited by new challenges.

Xtra Space offers our clients a turn key process from the initial consultation and feasibility though to gaining planning consent.

Our in house design team has a wealth of experience and over the years have built up a good relationship with many local planners and will guide you through the whole process.

Residential conversions, extensions and basements come in a variety of styles and specifications depending on individual needs, and we are here to advise and handle all your building permit and building control requirements. Once we have agreed the design of your project, we will manage the planning applications and lead you through each step of the process.

It is important to bear in mind that statutory consents are the necessary permissions required when making changes to a property and that homeowners have a responsibility to comply with relevant and current planning legislation. Therefore some, or all, of the following may apply:

  • License to alter
  • Pre applications
  • Landlords consent
  • Party wall agreements
  • Certificate of lawful development (permitted development)
  • Planning permissions
  • Conservation area consent
  • Listed building consent
  • Building regulations approval

Our project managers work closely with the clients and the tradesmen to ensure fluent continuity from start to finish, while managing clients expectations and quality control.

Our own internal Xtra Space architects will work on everything from planning permission to ensuring the house renovation is built to the latest building regulations.
