Closing in 2 storey hallway, to extend ensuite

Hi Helen, it helps if you can find find a local professional to take a look at the job. You will ideally need a feasibility study / building survey, Building Regulations Approval (architectural drawings) will be necessary and possibly also planning permission (drawing submission also) though only your local authority can confirm this. Your building a new load bearing floor and installing a bathroom so it also involves plumbing, drainage and electrical. Not straightforward but you just need to go through the process. Hope that helps.

It sounds a better use of space. Would basiclally require a measurement survey from someone like me to prepare drgs and calcs for building regs approval.

Hi Helen To start, you should hire a proffesioanl to visit the site and give you a feasibility report. If is possible to due the space, stairs location and layout, the proffesioanl will guide you into the process which includes a survey, proposed options, a possible planning application and last stage the construction docuemnts, including structural calcs and building regs. Hope ti helps you

Hi Helen, The first step would be to engage a professional (I would recommend an architect) to visit your property and advise on the feasibility of what you’re proposing. What you’re suggesting could be possible in principle, but it will very much depend on the specifics of your house: for example whether there is sufficient head height above the stairs. An architect would be able to guide you through the design process and explore different layout and design solutions with you. There may also be options to retain the existing windows in order to minimise alterations to the facade and save some money. You would also need input from a structural engineer to design the additional floor structure to support the shower tray, and to assess whether any walls being altered or removed are structural (including the need for a lintel if required). Finally, the architect and engineer would need prepare the drawings and structural calculations required for submission to Building Control before your builder can start on site.
