Homes in the East of England

Housing in the East of England ranges from post-war estates and modern developments to timber-framed and period homes in historic towns, so permitted development checks and conservation controls both feature regularly.

What goes into a double-storey extension?

Two-storey work has to sit comfortably with the house and the neighbours, so most of the design effort goes into the roofline, window positions and how the new first floor connects to the landing. We handle the planning application, the structural design and the building control process, then build, roof and finish both floors.

  • Measured survey, design and planning drawings
  • Foundations, steelwork, brick and block walls, roof
  • Joining the new first floor to the existing landing

What is the guide price for a double-storey extension in Hoddesdon?

What approvals does a double-storey extension need in England?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

Two-storey rear extensions can sometimes be permitted development in England (no more than 3 m deep, at least 7 m from the rear boundary, roof pitch to match), but most two-storey and all two-storey side extensions need householder planning permission.

What can affect a double-storey extension?

  • Neighbours’ light is assessed using the 45-degree guide many councils use.
  • The first-floor link can mean moving a bathroom or reshaping the landing.

What people ask before starting

How long does a two-storey extension take?

Around 14 to 24 weeks on site, plus the planning period before that.

Most people stay. The noisiest stage is when we break through into the existing first floor, which we plan for a short window.

Who deals with the council for a project in Hoddesdon?

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
