Renovating Design Dilemma Bedrooms

loft conversion size

5 years ago

Hi Houzzers,
We are exploring the idea of converting our loft. It has a footprint of 6x8m with a height of 3.5m. Can anyone guide me on what size of finished master suite we could expect?
Many thanks
Chris

This is a rather difficult question to answer..Best way to go about it is to measure the size of the footprint with at least 1.5m head room from the floor..each roof pitch is different and therefore the area available will vary...

Also to bear in mind if you are doing it under Permitted Development rules, there are limitations as to how much space you can add:-

A loft conversion for your house is considered to be permitted development, not requiring an application for planning permission, subject to the following limits and conditions:
- A volume allowance of 40 cubic metres additional roof space for terraced houses*
- A volume allowance of 50 cubic metres additional roof space for detached and semi-detached houses*
- No extension beyond the plane of the existing roof slope of the principal elevation that fronts the highway
- No extension to be higher than the highest part of the roof
- Materials to be similar in appearance to the existing house
- No verandas, balconies or raised platforms
- Side-facing windows to be obscure-glazed; any opening to be 1.7m above the floor
- Roof extensions not to be permitted development in designated areas**
- Roof extensions, apart from hip to gable ones, to be set back, as far as practicable, at least 20cm from the original eaves
- The roof enlargement cannot overhang the outer face of the wall of the original house.
Please note: For an explanation of how to apply the 20cm set back condition please see pages 35-36 of 'Permitted development for householders - Technical guidance', see below.

*Bear in mind that any previous roof space additions must be included within the volume allowances listed above. Although you may not have created additional space a previous owner may have done so.

@Victoria, Well, now that you've asked... We got planning permission for the project back in November but the first builder we asked for a quote suggested that we were wasting a lot of potential by not putting another room up there (at the top/back of the first picture). So, I revised the drawing by adding another bedroom to the rear and putting another bathroom/en-suite where the void and resubmitting for planning. After some time, the structural engineer came up with drawings and calculations for the project and the builder's quote came in @ £125k. With VAT on top of that, we just can't justify spending that much and was expecting it to be less. So, the whole project is on hold while we consider our options... Thanks for your interest.

Extensions are a great way to tranform a house into more friendly living space. Bi-folding doors, a nice big dining table in the middle and some quirky scandi furniture look amazing in building extensions.
