Needing expert architect drawings for a driveway we couldn’t have chosen a better, more professional, friendly company than DSB. They’ve supported us, explained things and kept us informed every step of the way. If we ever need anything again, they will be our Number 1 choice. Thankyou to all you. More...

DSB did an excellent job with the planning and Building Control stage of our project, which was a rear extension, completing all the required forms and submissions for approval - this was completely touch free for us. We were kept constantly informed of where we were in the process. Our builder commented that the technical plans were some of the best he had seen. We would definitely recommend Dave. More...

On recommendation we contacted DSB to help us design a new open-plan kitchen and living room. We had previously been told elsewhere that certain aspects we wanted weren’t possible. Not only did Dave help us to achieve our original aim he improved our plan with very helpful suggestions. We are delighted with the outcome!Every stage of the process was explained in detail at the outset and followed throughout. We certainly will recommend Dave Blacker to anyone. More...

I found Dave to be both personable and professional. I was having a re-modelling a of a bungalow including a loft conversion. He spent a morning explaining what he would provide, with examples, and finding out what I wanted to do with the house, all under no obligation.
Once the contract was confirmed, he visited again with the surveying equipment, and spent several hours mapping the house out. He explained what would happen at each stage and the expected timeline involved. I received a PDF of the draft plans, which I proofed, and after a few corrections, which Dave did quickly with no fuss, submitted for the certificate of lawful development. This went through without a hitch, and once received, he drew up the building regs plans, which again once submitted passed.
I would highly recommend DSB Property designs as Dave ensured the process was stress free. Every time I needed to contact him I either got straight through to him, or his associate, or left a message which was always returned either the same day or the day after.


Each case differs so without a site visit it is difficult to say but in general the main points to look for are as follows: -

1) What is the the existing head room available, the headroom available will normally be reduced as the floors levels may need to be built up to
match those of the house. Where this is not achievable it may be necessary to raise the roof.
2) Does the level difference allow the build up of insulation and floor finishes required to allow suitable remaining headroom and matching floor
levels with the house where required. There are various insulation solutions so levels required will vary.

We can provide an initial free site visit to establish whether are not it is possible to convert the garage as it is or whether you will need to make other alterations to make it work.

The initial stage will consist of us visiting your property, we will advise you what is possible and what is required. We will then provide you with a detailed quotation listing third party fee's such as Planning permission and Building regulations approval costs. Should you decide to proceed with our quotation we will then conduct a detailed measured survey of the existing property using Total stations and laser measure all linked to a tablet PC. Once we have this information we will prepare detailed plans for you to consider. Once the final design has been agreed, we will then finalise the plans and apply for Planning Permission or a lawful development certificate on your behalf. (subject to which applies to your scheme). The required consultation period for Planning Applications is normally eight weeks, during which time the local authority will publicise details of the project for public comment. The council fee is paid direct to the Council we will provide you with a reference number and covering letter at this stage. Many Garage conversions may not need planning but in some cases permitted development rights may have been removed as a condition of the original planning in which case a planning application will be required.

Assuming Planning permission is granted the next stage is the Building regulations process. We will prepare the plans in accordance with the regulations and send the plans to our structural engineer to calculate any structural works, a cost will be obtained from the engineer separately, (The Structural Engineer we use is a Chartered Engineer with over 40 years experience and holds Professional Indemnity insurance) a Building Regulations application will then be submitted to the council. Once approved they will check the works on site once works begin.

As with any alterations each case varies and we will be able to advise you when visiting your property for a free no obligation quotation but as a general guide, the main constraint for a loft conversion is the clear headroom required above an existing and proposed staircase, a minimum 2.0m headroom will be required and your existing ridge height will normally determine this for the proposed staircase. We suggest a minimum existing clearance of 2.250m from top of joists to underside of ridge will be required assuming the existing joists are a minimum 100mm, this will normally give you a 2.0m clear head height once converted after joists are upgraded and new insulation is installed, you will most likely require a dormer if the space is tight.

The type of roof whether it is trussed or traditional will also determine how expensive the conversion will be. Trussed roofs can be converted but will require more alterations and additional supports, in some cases ceiling may need to be dropped or the pitched raised to achieve suitable headroom but this may not always be possible. Traditional hand cut roofs are normally easier to convert.

The location of the staircase will play a fundamental part in the design, in some cases you may need to lose part of a room to fit the new staircase in.
