A local family run business, with over
30 years’ experience in extensions,
refurbishments and new builds covering

The company is run by myself and my step father who are both carpenters by trade.

We are a well-established team and we also work closely with an excellent team of sub-contractors, who each specialise in their own trade to turn your vision into reality. We support and run an apprenticeship scheme to pass our experience and quality onto future generations.

We pride ourselves on giving accurate, detailed and itemised quotations to ensure there are no nasty hidden extras on your project. We also listen carefully to your requirements and will offer guidance if you would like it.

We provide a professional, reliable and efficient service from your initial quotation, through project and post completion with any further queries you may have.

We are fully insured to undertake any jobs and all our works come with a guarantee.

  • I am more than happy to recommend JM Construction following the excellent results delivered with our Kitchen/Diner extension. From the very first visit the service was first class. James's knowledge and imagination helped us right from the start. Fresh ideas improved upon our drawings and helping us achieve these changes whilst working within our tight budget was very satisfying. The quotation was clear, the stage payments were always for work completed and the final price was kept in budget.

    The site was cleared at the end of every day. The guys on site were polite and very helpful, it felt more like having friends around. A concerted effort was made to avoid nuisance to my neighbours who also were very impressed with the service. The quality of finish was superb and I consider myself quite fussy. James has an answer for every question before it is even asked, always at least one step ahead of things. When telephoned with queries a response was always immediate. I was kept informed of the schedule and targets were always met.

    I am over the moon with what we have been achieved here at the cottage and cannot recommend JM Construction enough.

  • We wish to put on record for you to use as you see fit in support of your promotions for your building works our satisfaction with the entire project undertaken by you and your team. During the entire 5. months that the project was on going at no time did you ever leave us unsupported, or without a kitchen facility, heating, water, electricity, and when we were away you saw to it that the house was fully secured at all stages.

    Your team of craftsmen were always good natured and worked around our rather complicated life style without fuss. The quality of work done, and the problem-solving skills they applied to overcome the rather inadequate support by our other suppliers and their un fathomable instructions was quite frankly amazing.

    We are absolutely delighted with the end result.

  • We would recommend JMC without hesitation. James and his team have recently completed an extension on our house, and we have been impressed with the high quality of work and the excellent communication throughout the project.

    The work involved a double storey extension plus structural work within the existing house. We particularly liked the fact that JMC made our house habitable throughout, as well as the continuity of the teams James uses - when the electricians, plumbers, groundworkers, plasterers, carpenters etc etc are due back, it is reassuring to know they will be same people rather than a string of unknown tradespeople. JMC brought the project in to time and to budget, and also offered advice at the start on ways to save costs with suggestions on our plans. In summary, we couldn’t fault the project and thoroughly recommend JMC.

    Mr & Mrs Holland (Stratford)

  • Fantastic, professional and always courteous. We are SO pleased with the results.

    We found the whole team trustworthy and reliable and happily adjusted their working day to accommodate our young family’s needs.

    Would highly recommend.

    Mrs Keel (Milverton)

  • I am so happy with the work that James Mann has done on my house. From start to finish, everything ran smoothly, on time and within budget"

    James has always been available to contact, and endeavoured to complete extra tasks when I requested them.

    Pleasure to work with. Thank you!

From small porches to 2 storey extensions, we can quote for a wide range of building works.

We work closely with select local architects who can help realise your vision. We can offer advice from the design and planning stage right through to the construction and those all-important finishing touches.

Extensions under permitted development

With house prices going up and up, taking advantage of the relaxed planning laws is often the best way of creating your dream home. Check out the link to the planning portal mini guides to see what you can and can’t do; www.planningportal.co.uk

Loft Conversions

Whether it’s a hip to gable with a full dormer or just a simple conversion. James Mann Construction can help you to achieve the extra space you require. From simply converting the loft space you already have; to making the most out of your loft with full dormer conversions.

Using your loft is a really cost effect way of gaining an extra room without having to do an extension. Now with new relaxed planning laws you can often do this under permitted development saving the additional time and stress of applying for planning permission.
