This is dependant on the height of the roof ridge. If you were to stand in the centre of the roof and measure from the top of the existing ceiling joists to the ridge board at the apex of the roof and you have a minimum of 2.2 metres, then the loft can be converted.  We’d only be happy to discuss and advise you, and visit your home to undertake a free site survey.

All houses have permitted development rights from the local authority. If the property has never had an extension then a loft conversion may not need planning permission as no permitted development has been used. If the property has been extended then the extension would have to be calculated and subtracted from the permitted development allowance. If there is insufficient allowance, then planning permission will have to be applied for.  All proposed loft conversions will need to meet the latest building regulations. Everest Loft Conversions can help and advise you in all areas of planning permission.

Yes, this is needed by the local authority building regulations. All work must be verified by structural engineers and authority inspectors before construction can commence. Everest Loft Conversions again can manage all planning aspects of the project on your behalf. Roof enlargements and alterations such as loft conversion are permitted providing that they do not exceed the highest part of the existing roof and do not materially alter the shape of the dwelling.

A loft conversion will significantly add value to your home and is one of the best investments you can make to your property not to mention all the added extra room you will gain.

Typically loft conversions timescale will differ with each property and the complexity of the project. This is dependant on the size of the loft, type of conversion and any pre-maintenance work that will have to be carried out. The conversion will typically take place 4 to 6 weeks from date of permission is granted and the conversion itself should take approximately 6 weeks before being fully completed.

When we start any building work on your loft conversion it will depend on a few factors such as our current workflow and completion of any planning beforehand. Usually we can start work on your loft conversion within 3 months from the intial agreed proposal.

A building project such as a loft conversion will have some impact on the daily routine of the household at some stage depending on the scale and type of the project involved. The way we plan out our work schedules is to keep disruption at a minimum where possible. We will also keep you regularly informed and give good notice of major work and impact to prepare the household. We recognise that trust is important and will safeguard every client’s privacy and intrusion rights.

A deposit will be required to secure the loft conversion development, which will be 10% of the overall quoted price for the project. Then payments will be required on a step by step process as work is carried out and completed, so you can verify you’re happy with the progress made. Everything will be detailed in the initial proposal after we have assessed your property.

Permitted Development Rights come with most houses, and they enable you to build a certain additional volume without planning permission.

Permitted Development Rights enable you to extend up to 15% of the existing house in volume, or 70 cubic metres, whichever is greater. For terraced houses, this is reduced to 10% or 50m, in both cases, the maximum enlargement is 115 cubic metres, the volume is reduced to 10% or 50 cubic metres within a conservation area.

The extensions must be no higher than the existing house.

Roof enlargements and alterations such as loft conversion are permitted providing that they do not exceed the highest part of the existing roof and do not materially alter the shape of the dwelling.

Loft dormers are permitted if it adds less than 50 cubic metres to the volume of the roof space for detached and semi-detached houses (40 cubic metres in terraced houses). The dormer must not face the highway and it must not be higher than the existing roofline. If your planned loft does transgress on any of these points, it doesn’t mean that it is prohibited, but you will have to apply for planning permission.

Any previous roof space addition has to be included in the calculation and building control inspectorate will always be involved.
