These 'modern day' estates can be rather complex.
For instance, the estate I live on (where we hold the Wycombe meet) comprised originally of three farms. The development where I live, Manor Farm, was built first, and as Leasehold. All purchasers have to sign covenants, agreeing to things like, no outside aerials, no chickens to be kept, no noisy or dangerous animals, decorating to be every three years, etc etc.
There is a management company set up comprising home owners. They see to the estate on behalf of the Leaseholder. The leases are split into two...frontage and property/rear garden.
Most of us have brought the freehold. You can only buy the property freehold, but the frontage is what they call 'merged'. In a nutshell, you own the grass on top, but the original Leaseholder owns the ground below. And the covenants still apply. You still have to pay maintenance charges to have the grass cut, and general upkeep of the estate.
If you require to add an extension, the correct way is to submit plans, etc to the management committee for approval. If you skip this, and go straight to the council for planning permission, even if you get it, the management committee can overrule, (another covenant rule). One family in my road found out to their cost, as their proposed kitchen extension, although within the building land, would have encroutched onto the frontage. Therefore after ordering bricks etc, they all had to go.
As regards Jamie's point about aerials, people started putting dishes up around the estate. The Leaseholder then sold all remaining leases to a new Leaseholder from a company in London (the original fella actually lived on the estate, just near me.)
The New Leaseholder toured the estate, and started picking on lessee's about their aerials, and if anyone started kicking up, he tried to charge them a subsidy. He asked one householder for £40, was told to FO, so then charged £60 !!!! He even threatened to make people put their windows back to original spec. !!!
However, as I said earlier, the Estate is in three developments, and he started causing trouble with another management company, who held together, took legal advice. It all comes under such things as your human rights, to coin a phrase, and being allowed to live in peace. From what I gather, the court ruled in the management committee's favour, and its all gone quiet now.
Luckily, as the covenants and Leases are different for all three area, he has not chucked his weight around this side too much.
This is why it is so important that the legal team do thorough surveys when you buy a property.
Covenants and agreements stand today, as they did donkey's years ago.
Sorry if off the OP....but thought I needed to say a bit
