Who do I need and what will it cost?

[partystress]

I am buying a small Victorian end-of-terrace. Location is perfect, but it is too small, and there is definite potential to extend. It’s in a conservation area, which I think means no permitted development rights, everything needs PP.

I want someone to help me weigh up the feasibility and pros and cons (including rough costs) of different options (eg double storey extension vs single + loft conversion) before I submit a request to the council for an informal opinion. Then I would get proper drawings done to apply for PP.

Is this a service an architect would offer, or do I need an architectural technician or simply a decent builder? And any idea of costs would be really helpful. Thank you.

Hi there,
You need an architect/structural engineer. Personally, set up an appointment with your councils planning office, take some photos of the property with you and use a dry wipe marker to show the planning office what you are looking for and if it would be feasible. The council may charge a fee around £150 for the service, make sure you leave with something in writing.
Have an architect design your dream but ensure they also do structural/building regs. This service as a whole should be from around £2 upwards.
As for the construction works, find a reputable builder, these are hard to come by (I was lucky after the 6th builder). Going rate is from £2k-3k per m² (lower - higher end) so if you are looking at an extension which is going out 4 meters and by 8 metres wide then 36m²x 2k you are looking at around £72k this would be for the shell. The kitchen for example would not be included.
Good luck, if you need any help just PM me directly.

Which area are you in?

Thanks @BMasters. I’m in the SE. Local council doesn’t seem to offer meetings, just a form-based informal opinion service.
