Extensions & Loft Conversions in Upminster
In Upminster and across Havering we are most often asked for two-storey side extensions and rear extensions and kitchen remodelling. Around half the borough feels semi-rural and much of that is Green Belt, which limits how far houses there can be enlarged. Gidea Park and Emerson Park have their own conservation or special character policies, including on front boundaries and plot coverage.

FAQ
Extensions & Lofts in Upminster
Not answered here? Call 07595 386864 and ask us directly.
Do you carry out extensions & loft conversions in Upminster?
Yes. Upminster is in Havering, where we work every week alongside Romford, Hornchurch, Rainham and Harold Wood.
Do I need planning permission for an extension?
Not always. Many single-storey rear extensions and loft conversions fall under permitted development, which has size limits and does not apply to flats, maisonettes or some conservation areas. We check your property at the site visit and tell you which route applies before you spend anything on drawings.
How long does an extension take?
A typical single-storey rear extension takes around 10 to 14 weeks on site once approvals are in place. A loft conversion is usually 8 to 12 weeks. We give you a written programme with the quote so you know what happens each week.
Can we live in the house during the work?
Usually yes. We seal off the working area, keep a kitchen and bathroom running wherever possible, and agree the noisy or dusty days with you in advance.
