Timber Frame Building Design

1. Receipt of Building Regulations drawings package.

Upon receipt of your frozen design package, we will review the content to ensure that this matches our scope of supply and estimate documents, at which point we will get our design team to commence design on the project.

Drawings required from yourself typically are building regulations standard or construction issue in both PDF and DWG formats;

  • Plans showing full build ups and Timber Frame positioning.

  • Sections showing full build ups and Timber Frame positioning.

  • Build up details and specifications.

  • Any information available in terms of utilised systems such as MVHR, underfloor heating, Solar etc – their locations, weights, and specifications.

The above helps us set the parameters accurately for design setting out, whilst also being able to value engineer your project by accurately allowing for the loadings required and not going above and beyond in engineering.  Often ensuring we have information about underfloor heating for example allows us to engineer and avoid rework later down the line.

Something we do get asked on occasions is ‘future allowance’. Even if you do not intend to install the likes of a lift for instance through the floor zone, or solar panels at the point of yourself building the project, it may be a good consideration to include the loading for such, in the event that future residents may consider this.

The first issue of design co-ordination from ourselves at FBUK would be the engineered line and point loads. The issue of these will form a large part of your structural design below ground and within your structural slab ahead of our commencement on site. It is imperative that these are issued to your structural engineer and that all loads are catered for within your foundation and substructure arrangement.

Please note that we are not responsible for your foundation and slab engineering and detailing.

3. Preliminary design issue.

Once we have the line and point loads we are able to apply these to our initial designs and in turn issue to yourself for review, comment and approval where relevant. This initial issue will be titled P1 (preliminary 1).

In terms of your review, we will request that you in turn look through each individual document issue, mark up any specifics for comment, amendment or in the case of approval, stamp the drawings by means of status A,B or C.

Let’s dive into the details!

The time it takes for  architectural plans to reach the design stage can vary depending on a variety of factors. However, on average, the duration can range from a few weeks to several months. The timeline primarily depends on the complexity and scale of the project, the level of detail required, and the collaboration between the architect and the client.
