Bungalows - roof conversion or huge extension

[JP_]

I am looking to buy a 3 bed bungalow. It is a long one (6m wide, but with entrance middle side, two bedrooms to the front), but a 30m (100ft) long garden.
Neighbour has done a roof conversion with 3 or 4 bedrooms (I would only put 3 in). I want to make it a 3 bed + office + play room bungalow (so, 5 bed) -and get another shower/WC in there, maybe an ensuite too!

I am trying to weigh up what I would do if I bought it, so just throwing this out there.

Option 1: convert loft space to create new rooms, then add a nice living room at the back.

Option 2: Build a huge rear extension - say, 10m long. there is possible space to build a 3m wide room next to a 4m wide room, which would allow both kitchen and living rooms to face the garden. Then could have two small bedrooms with side windows between current house and those rooms.

I am guessing that the big extension downstairs will be the cheapest, fastest and least disruptive option, but might be trickier with planning permission?

Just wondering if anybody has had this dilemma, and how it went. Ta!

It's it just a design/layout question and you're fairly sure planning permission will be forthcoming?

If not you may have a option c) what would I do if my grand plan is considered overdevelopment and I have to work within a modest planning addition followed by maxing out my PD.

Have you got an approx floorplan? What could you do under PD - as that will be your fallback if PP not forthcoming?
i.e. Dormers upstairs plus large (8m) rear extension.

That's a good point. I have a rough idea of what I would do for a ground floor extension, and this should be less than 8m, I think. Maybe more from original house, but less from the end of the kitchen extension that was done in 1976.

Looking at the place in a couple of hours.....

Well, I looked at the house, and I like it. Now the fun and games begin....

It has a nice tall loft space - lots of room! And the garage, which I was going to knock down, actually looks pretty good - long, solid, nice roof structure - easy to convert into a useful room ...

Just need to buy the damn thing now!

What did the rest of the street look like? Similar bungalows? Any of them developed?

All different really, although the neighbour has the same house, and is in the process of a loft conversion with additional downstairs space, and have moved the garage. 2 doors down they have a side dormer.



The back garden is about 30m long and no house behind it

This is what the neighbour is currently doing:

Re-thought the garage situation. New plan. Does this look like it will come under PD?
