Hi folks,
I'm in the process of buying a first floor flat in SW London. It's a Victorian end-of-terrace house, about 950 sq ft, and it needs complete renovation. I'm planning to do a loft extension at the same time - to get everything done up front, before moving in, while it's an uninhabited building site.
When I say 'complete renovation' I mean it needs:
Loft extension (1x ensuite bedroom, likely a Mansard extension)
1x wall knocked down between kitchen and dining room
Gas central heating throughout (i.e. boiler, piping, radiators in every room)
Electrics (*)
1x bathroom completely replaced
1x kitchen completely replaced
1x functional fireplace removed and replaced with decorative fireplace
2x disused (boarded up) fireplaces uncovered and replaced with decorative fireplaces
Re-plastering
Painting
*I'm not sure what is needed from an electrical perspective since I have a "domestic electrical installation certificate" from NICEIC dated 2019 (which is reassuring) but there are hardly any sockets in the rooms and all the switches are very, very old looking. The consumer unit looks brand new, though.
Bearing in mind that I am a COMPLETE beginner, this is pretty scary/terrifying/exciting. You'll probably see a lot of posts from me in due course.
To begin with, I'm looking for help with a couple of questions around design and planning.
1. The neighbour submitted a successful planning permission application for the same extension in 2017. I have downloaded the application, including very useful technical drawings of the planned extension. Is it possible to re-use these to save me some money? (We have the same house, albeit mirror image). I'm wondering if it is possible to get bespoke versions created at a discount since the work has already been 'done' by the original architect / architectural technician / structural engineer. Also, which of these 3 professions is best suited to my needs? I struggle to understand the difference between them.
2. I know that in London, getting a loft extension has become 'productized' in that you can buy such extensions as packages from dedicated loft extension companies. However, since I'm looking for a loft extension AND an entire renovation of the underlying house, should I steer clear of these dedicated companies and go for another type of building company? I'm keen to keep the whole job centralized to one contractor organization, who then liases with all the subcontractors on my behalf. Any suggestions on where to look?
3. Are the neighbours' plans (from the planning website) sufficient to get a realistic 'quote' for my property, even if I don't end up using them and need to get my own designs made up. I'm keen to start the process of getting quotes immediately while the house purchase is processing.
Massive thanks for any input! I'll be sure to respond back.
