House Extensions in Doncaster

City of Doncaster Council. They determine householder and full applications for the city and its outlying villages, and they apply their own local plan alongside national policy. We submit through the Planning Portal and correspond with the case officer directly.

Usually, provided the addition is not disproportionate over and above the original building. That test compares what you propose against the house as it originally stood, so any extension built by a previous owner counts towards the total. It is a narrower assessment than a normal householder application.

The dwelling as it stood at a fixed historical point set out in policy, not as it was when you bought it. That is why the planning history of the property matters. A conservatory or rear extension added in the 1990s reduces what is available to you now, even though you had nothing to do with it.

It is shown on the council's policies map, and we check it for your specific address as part of the first stage. It is not something you can judge from the look of the street, because the boundary often runs behind a row of ordinary suburban houses.

Not always. Many single storey rear extensions fall within householder permitted development, subject to limits on depth, height and garden coverage. Rights are reduced on designated land, do not apply to flats, and can be removed by an Article 4 direction or by a condition on the original permission.

Sometimes, but the existing garage foundations and walls were rarely designed to carry a floor and a wall above. An engineer assesses what is actually there, and the answer is to strengthen, to underpin or to rebuild the base. That assessment belongs before the price rather than after the design.

It depends what it is for. An annexe or outbuilding gives independence and can suit a family member or a home office better than an attached room. It has its own planning position, particularly around whether it is genuinely ancillary to the main house, and that is worth establishing before designing it.

They can be. Depth depends on the soil, on any mature trees near the excavation and on reaching a stable bearing, and shrinkable clay with trees nearby is the combination that pushes a trench deeper. Building control inspects the excavation before concrete goes in and that sets the depth in practice.

If the work cuts into a shared wall, is built up to the boundary line, or involves excavation close to a neighbour's foundations, the Party Wall etc. Act 1996 requires notice. Many neighbours consent in writing. The notice periods run into weeks, so they are served at design stage.

Yes. The outlying villages fall to the same authority, and we also work north towards Selby and Goole, which are decided by North Yorkshire Council and East Riding of Yorkshire Council respectively. Which authority applies is the first thing we confirm.

Yes. The architect who designs your extension oversees the build, so what is drawn is what gets constructed, and the build cost quoted at the outset is the one we stick to. There is no handover to a separate builder partway through.
