Architect plans for replacement garage and submission for Planning permission.
Sean provided a very professional service after we required an existing garage to be demolished and a plans for a replacement to be drawn up and submitted to our local council for permission. This was done in a very efficient manner and despite Covid intervening and delaying construction, we were very pleased with the way work progressed to completion and would have no hesitation in recommending Sean.

Garage conversion. Converted half of existing integrated double garage into office/spare room.
Used Sean for both architectural services and building project management and was happy with all services. Sean did all of the drawings and made all correspondence with the council to obtain the correct building warrant. He organised all building work and trades personnel. All work was carried out in the estimated time line, within budget and up to a good standard. Wouldn't hesitate to recommend or use again.

Garage conversion and utility extension
Sean came up with the drawings and then project managed all the work for our garage conversion and utility extension. The process was completely hassle-free for us. The builders and tradespeople were all excellent and turned up exactly when they should, did a great job and left everything clean and tidy. Sean kept us informed and carried out inspections regularly to check everything was on track. He was very easy to get in touch with and responded promptly to any queries. I would 100% recommend Sean. We are delighted with the work.

Rear open plan Kitchen, Dining, Living Extension.
The works were carried out as and when agreed, to a high standard. Sean was very helpful from start to finish . Including a complete change of layout mid construction.
Mr Melvin, Sunnyside Avenue, Drumoak, Aberdeenshire.
Extension to create a larger family room
Once project started the works took place smoothly with no real breaks in work, the works were planned well with extension more or less complete prior to the breakthrough meaning the disruption to the house was minimal. I was satisfied that all works were carried out to a high standard with any small snags dealt with in a timely manner.
Mr Lovie, Forest Park, Stonehaven, Aberdeenshire.
Sunroom extension designed and overseen
Sean designed and excellent sunroom within the criteria given, applied for and achieved planning/building warrants, helped to select the tradespeople, oversaw the work with periodic visits, signed it off when finished and finally submitted details for and obtained the completion certificate. I also requested some changes to the plans which turned out to be an error of judgement and Sean very professionally oversaw a mid-build change which completely saved the day, all without fuss and for which I am extremely grateful. A first class service service.

Mr & Mrs Sadler, Maidencraig View, Aberdeen.
Prepared plans and got planning approval for house extension. Sean successfully argued when plans queried that they were correct so we got the extension we wanted.
Sean is professional, helpful and offered practical suggestions about what would work for our extension. Total time from drawing up plans to getting building warrant approval took approx 6 weeks.
Mr & Mrs Glasgow, Oldfold Crescent, Milltimber, Aberdeen.
New extension - listed building
Sean designed a large extension (kitchen and utility room) for us. Our house is listed and in a conservation area so it was complex. He dealt with building inspectors/ council offices/ planning etc all with a professional and courteous manner. Very personable and competent architect.

Plans drawn up for garage conversion and co-ordination of builders
Sean came on recommendation from my sister (also for garage conversion). Sean was clear about costs Upfront and used trusted workmen to carry out the job (they were also reliable and did a great job). He sorted out the building warranty and then the work began. He insured quality inspections were carried out throughout the work as well as the end. Sean is very personable and professional and was easily contactable if a question arose.
