Sussex Garden Rooms

How We Work

The A-Z process for designing and building your annex.


Give us a call on 07899 961562 or email us regarding your potential project.


We’ll let you know approximate costs and can get you a sample proposal with previous designs and options available.


If you’re happy with that we can arrange an initial free of charge video consultation to assess the proposed location and discuss details around groundworks and foundations.


If for a garden room we can the send a detailed proposal with a full quotation.


If for an annex (which requires planning permission) we would then encourage you to purchase our Planning Package Service, which include the following:

  • In person site survey to assess and measure the site 
  • Provision of a full sales proposal for the annex including designs and animation 
  • Process the council application including the fee
  • Provide all associated drawings and plans.
  • All council liaisons 
  • Groundworks survey and quote

At this point we will also assign you a provisional build slot in our calendar. 

Cost of Planning Package Service: £1,500 inc VAT


When planning is approved we can then take a deposit for your build and confirm the build slot. We will order your structure and schedule the groundworks and book in the foundations installation.


We will put you in touch with Howdens to specify and ensign your kitchen. We will also let you know the Victoria Plum specification of the bathroom and confirm choices of panels and flooring.


We then come and build your annex which should take no more than 4-6 weeks to complete!


We handover the keys and your post build guarantee commences.
